For my first post, I’m sharing a letter @NVIDIA signed on why open models matter. AI will transform every industry, power every company, and be built by every country. Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty. The world needs both frontier closed models and frontier open models. https://t.co/AUKzoQ5Ikb

Some observations on Kimi: 1. It's a very good model! I don't think its performance can be explained away by distillation or anything like that. In agentic coding sessions, it seems pretty much on par with the best public models of Q1 2026. In my fairly limited use, it also seemed very token hungry. It's not obvious to me that this model is actually that cheap to run. 2. I am personally surprised the Chinese state continues to allow the open sourcing of models this good, given potential risks. To be clear, I *myself* might be fine with models presenting this level of marginal risk being open weight, but I am surprised that China is fine with it. I suspect the reason they are is 75% explained by strategic blindness/lack of AGI-pilledness (the CCP is very Yann Lecun-y in its views of AI). The other 25% or so is their lack of compute for customer inference (making China's open-weight strategy an unintended byproduct of US export controls) and the normal Chinese strategy of aggressive exports. For the companies, as opposed to the government, the decision to open source is partially ideological and partially because they are behind, and they know that very few people would pay for sub-frontier models from China. 3. Open-weight models are inherently decelerationist, and I'm continually surprised to see the so-called "accelerationists" so excited about open-weight models. I suspect the reason they are is that they know open-weight models are effectively ungovernable, and they simply like the overall cloak of ungovernability open-weight models create over the whole of AI. It's not a bad strategy; it reminds me of James Scott's recounting of the hill people in "the art of not being governed." Still, in the end, open-weight models deter further AI capex. 4. One probable outcome of an open-weight-model-dominant world is full AI communism, which is precisely what China proposes: rather than a market product, AI is a "public good" which will ultimately be provided by the state as a kind of "digital public infrastructure." This future strikes me as a dystopian hellscape, but I've never met an open-weight models advocate who doesn't ultimately concede this is where things end. You'd be surprised how many 'accelerationists' lobbied me, while I was in government, to support an eleven or twelve-figure federally funded data center so that startups could train models at a subsidy and then give them away for free. There was no other way for AI to progress, they said. Perhaps this is the logical end state of things. Nonetheless, I find myself surprised to see supposed accelerationists excited about such an outcome. I think many of them just don't know what they're doing. Many accelerationists do not view the creation and serving of frontier models as a legitimate business. 5. I would guess that the Trump Administration will at some point realize that their best strategy here would be to create large amounts of regulatory risk around the use of open-weight Chinese models. You don't need to "ban open source" (one of the dumber motifs of AI policy discussion). You just need to direct every agency to issue soft law that creates FUD. "A Federal Reserve Advisory Bulletin found that there may be backdoors in Chinese AI models." It needn't be that well justified. You just create enough regulatory risk that every regulated enterprise backs off. You probably don't want to create so much regulatory risk that you scare off the hyperscalers from serving Chinese models; this will just drive startups to sketchier providers. There's a happy middle ground here. I'd assume they will do some version of this. 6. It's probably true that open-weight models of this capability make the world a bit more dangerous, but not so much more that you'll really notice. At some point the models will be capable enough that you will notice. "A nonliving, invisible, dangerous, and infinitely self-replicating agent escaped from a Chinese lab," you say? Color me shocked.

China just released an open source AI model that matches the best closed models from OpenAI and Anthropic. Gavin Baker explained exactly how they did it and the answer should concern every American AI lab. The model is called GLM 5.2. It was built by Z. AI. You get 744 billion parameters, 1 million token context window and its MIT license, meaning anyone can download it, fork it, build a company on it, with no restrictions and no Dario. It scored 51 points on the artificial analysis intelligence index. The highest score any open weight model has ever achieved. It beat GPT 5.5 on the frontier software engineering benchmark. It trails Claude Opus 4.8 by less than one percentage point. And it costs 85% less to run than GPT 5.5 for comparable performance. Gavin Baker said on the All-In podcast that this model has challenged some of his beliefs. Then he explained how China built it. The method is called distillation. Just think of tens of thousands of phones and computers running simultaneously, all hitting the frontier model APIs through masked accounts, asking specific questions, and harvesting what happens inside the model when it answers. Every reasoning step, every token. The entire thinking process gets recorded and fed back into the Chinese model during training. It is a cheat sheet. It is the answer key to the exam. And here is the part that should worry everyone. Sacks said it plainly. China was already nine months behind American models. But now that GLM 5.2 is good enough to run its own reinforcement learning, it can improve itself without needing to distill from American models anymore. The cheat sheet let them get close enough to start writing their own answers. Sacks said we are six months behind on the model and 24 months behind on silicon and they are only a few months behind in total. The Z. AI founder told Elon Musk directly that open weight fable-level capability will be here before Q1 2027. Every restriction Anthropic lobbied for, every self-imposed safety guardrail, every month of delay in releasing American frontier models accelerated this. The Chinese labs were not under those restrictions. They were not going to wait. The composable model future Gavin described, where every enterprise runs a frontier model alongside their own fine-tuned open weight model, is coming regardless of what American labs do next. The question is just whether the open weight half of that stack is American or Chinese. Right now it is Chinese. WATCH THE FULL PODCAST ON @theallinpod

I spent some time trying to distill all the complex factors impacting open models -- economics, capabilities, distribution, policy, etc. -- into a clear list of beliefs. Here they are in full. 1. It’s surprising that the top closed models did not show a growing capability margin over open models, based on compute differences for training and research, especially in the second half of 2025 and through today.

It is clear open source models and harnesses are having a moment. There's a few factors at work 1/ It is now obvious that you can catch up to near-SOTA performance and do so with a clear training lineage. See:@thinkymachines Inkling launch today. 2/ There are several well-funded, talented teams building open weight models now in the US and abroad. Along with the explosing of other near SOTA models (Grok/Cursor, Muse Spark), it is clear we are going to have a diverse ecosystem of models atleast on coding and agentic use. 3/ Organizations are increasingly looking for control over how their data is used and are willing to trade off some access to frontier level tokens for this control. Organizations and countries are increasingly nervous about the frontier labs potentially competing with them down the road and don't want their data to enable a future competitor. 4/ Open source is a slider: you could bring your own open harness, your evals, your business context and are free to pick and choose your model of choice. 5/ Companies have now actively shifted from "how do we get our people to use tokens" to being uncomfortable with their token cost ballooning without a clear line to revenue. 6/ Geo-politically, countries will be weighing open weight models as a way to get frontier-level tokens inside controlled environments that may not be otherwise possible. All of this leads to more choice for all of us !

Xi Jinping used his first-ever appearance at China’s World AI Conference to present Beijing’s vision for a new global AI order. He said AI has entered an "unprecedented" period of innovation, bringing enormous opportunities alongside new governance challenges. China’s proposed direction: -Open-source AI to promote "openness and win-win cooperation" -Opposition to countries "overstretching" national security and placing their own security above others (ofc he is referring to the USA) -Preventing unequal AI access from creating "new historical injustices" (He probably means that China should never again be historically left behind.) -5,000 AI training and seminar opportunities for developing countries over the next five years -New cooperation centers with ASEAN, the Arab League, African Union, CELAC, SCO and BRICS Xi also called for AI to remain under human control and for mechanisms addressing loss-of-control risks. This is an AI foreign-policy doctrine: open models as public goods, training as soft power and technical standards as geopolitical influence. tl;dr China sees AI and Open Source as its historical path to becoming a global superpower and says the USA, with its closed source technology, is trying to push China and its competitors behind an iron curtain.

Sundar Pichai just reminded everyone that Google was built on open source. He personally worked on Chromium, Android, and Kubernetes before becoming CEO. Three systems that power billions of devices today. Now Google is applying the same philosophy to AI. Their Gemma models are updated year after year, designed to run on edge devices rather than requiring massive cloud infrastructure. The question he got was why not release a large open source frontier model. His answer was revealing: frontier training requires enormous capex investment, and Google is putting billions into R&D to stay at the frontier. The open source AI landscape is quietly consolidating around a few players who can sustain the investment. Google's two decades of open source credibility gives them a position that's hard to replicate.

Nobody is talking about this. There's an open-source AI platform with 17.3K stars that connects to 40+ of your internal tools and runs completely on your own servers. It's called Onyx. Most companies using ChatGPT Enterprise are feeding sensitive internal data to OpenAI's cloud every single day. Onyx flips that. You self-host it. You control the LLM. Your documents, Slack messages, Notion pages, and Jira tickets stay on your infrastructure. The connectors are the killer feature. Onyx pulls live knowledge from Slack, Notion, Google Drive, Confluence, GitHub, Jira, and 35+ more then indexes everything with hybrid search and a knowledge graph that stays accurate at tens of millions of documents. Document permissioning mirrors your existing access controls automatically. If someone doesn't have access to a Confluence page, the AI won't surface it to them in answers. No extra config. No permission rebuilds. Everything else: → Custom agents with unique instructions and MCP tool access → Deep Research for complex multi-step questions → Code interpreter, image generation, web search → SSO, RBAC, full enterprise security stack → Docker, Kubernetes, Terraform full deployment flexibility MIT License on Community Edition. 17.3K stars. 2.3K forks. 192 contributors.

Cursor’s Composer 2 is likely built on Kimi K2.5. The model URL + tokenizer are strong signals. I love this direction: companies mid-train and post-train on top of OSS LLMs. Prediction: open-source model labs will monetize by taking a cut when others build on top of their models and scale to millions of real users. They will enforce this via licensing. That’s the flywheel. That’s how open-source AI thrives.
@VadimStrizheus ·
Dario is right about one thing. Open-source AI is not a magic button. > You still need chips. > You still need inference. > You still need someone to make it fast. But he skips the part builders care about. I don’t want local models because they are perfect. I want them because nobody can revoke them. If the best AI becomes an approval-list product, you need a way out. you need to own your own intelligence.

This is not another AI slop model. Don’t ignore it. I spent the last few hours playing with GLM 5.2 after a few friends told me I should pay closer attention. I was skeptical, as I usually am with open models. Most of the time, I find them way behind frontier labs. Not really comparable. But today felt different. I’m not saying it’s perfect, and I didn’t run some comprehensive benchmark suite. But across different domains and tasks, this is the first public open model that felt genuinely close to something like Opus 4.6. That is a crazy breakthrough. This feels like a ChatGPT moment for public open models. The catch: running it properly is still expensive. You probably need something like 8 Nvidia H200 GPUs, which means roughly $400K to buy or around $20K/month to rent. Not cheap. But for enterprises currently paying millions per month to Anthropic or OpenAI, this could become a serious disruption. Open models just got much harder to ignore.

Onyx just hit #1 on GitHub trending. Open source AI platform — self-hostable, works with every major LLM provider, and ships with: - Agentic RAG - Deep research mode - Custom agents - Web search - Code execution - Voice mode - Image generation - 50+ connectors out of the box This is what a self-hosted AI stack is starting to look like.

playing around with local AI models after I recently built out my home lab (DGX spark, mac mini, 5090 eGPU, strix halo framework, jet KVM etc). Running both Openclaw and Hermes Agent now. It’s super fun, def recommend! Lets you geek out, learn about AI, and also buy lots of gadgets lol a few observations: - it’s great for learning about AI. Now I actually care and will try out all the new models as they come out - Qwen 3.6, Gemma 4, etc. When there’s new tech like TurboQuant and DFlash, you can run them on your machine and see how it changes the performance profile - the software stack is interesting. You can use ollama/LM studio to just dabble, but over time I have things set up with LiteLLM (as a local router for LLM queries, depending on their complexity) going to VLLM. I have a faster model (35B MoE) and then a better model (122B) depending on what I’m using it for - the “big” local models (120B+ parameter) are slow unless you have a souped up GPU card. And not as good as the cloud LLMs. So as you tune your setup for maxing out tokens/s to make it as usable and responsive, you get a much better sense for all the tradeoffs - context window, KV cache, mem usage, mem bandwidth, parameter size, TTFT, etc - for those (like me) coming from SOTA cloud LLMs, you can’t help but compare. The open weight models are all about a year behind, but even then, as a consumer, you are generally running much smaller versions of the best local models. You probably won’t use anything bigger than a ~120B parameter model (GPT OSS 120B or Qwen 3.6 122B). Local AI models running on consumer hardware have 1/100th the size, are much slower (often 30-50 tok/s versus 100+ to be usable) - but because it’s been ~1year behind, it seems remarkable to think that we might be able to run Opus level local models in 2027. The latest open weight models are already pretty usable (just look at Qwen 3.6 27B dense) but its remarkable that it’ll keep improving - the hardware side is interesting. I started out with a Mac Mini, then a Nvidia DGX Spark. I also have a gaming rig. It turns out that the Mac hardware stack (particularly Mac Studios) are really good since they have pretty high bandwidth and large amounts of unified memory so you can run big models. (BUT GOOD LUCK GETTING A MAC STUDIO!). Shortages like crazy, and memory size cuts left and right. GPU cards are very fast, but only run much smaller models (24GB and 32GB are the popular consumer sizes for graphics cards), plus you have to put them in a big PC box. I got a 5090 eGPU but lots of issues with it :(. The new GB10/DGX Spark family of devices have big memory but relatively low memory bandwidth (so not the fastest tok/s) but you get CUDA and the whole ecosystem there - the biggest use case I’ve found with my local AI setup has been simple: lots of summarization and analysis. I’ve dumped all my personal emails and blog posts and google data and created detailed month-by-month markdown files that can then be queries. Every article I bookmark or every YouTube channel I subscribe to is summarized. for me the sweetspot has been low-ish priority, asynch, and where the problem doesn’t require SOTA You could argue that this is a lot of effort and $ for something that could probably be covered by my monthly GPT/Claude subscription. And that’s true! But the learning is the point :) so what’s a good way to start? I think you start with whatever you have. Ideally a nice Mac M5 laptop or a gaming PC that already has a good GPU. Just set it up so it stays on, and then point some set of Openclaw jobs at it. Or if you want to invest in a new piece of hardware, the DGX Spark or Strix Halo systems are nice to be able to try out bigger models, or you can go down the rabbit hole setting up racks with GPUs etc. Either way, super fun- highly recommend

MiniMax has open sourced M2.7, their open-source model designed "for agent-based workflows, complex reasoning, and real-world engineering tasks." It introduces self-evolution capabilities, where the model improves itself through iterative experimentation, achieving 30% performance gains and a 66.6% ML competition medal rate. Honestly, this is more impactful than expected. On the performance side, M2.7 delivers strong software engineering results (56.22% SWE-Pro), near top-tier benchmarks, and excels in multi-agent collaboration, tool use, and productivity tasks like document editing. With high ELO scores, fast incident recovery (<3 min), and 97% skill compliance, it positions itself as one of the most capable open-source AI systems right now.

The biggest threat to AI subscriptions... wasn't built by OpenAI. AI companies spent years convincing us that intelligence should live in the cloud. Pay every month. Stay online. Own nothing. Then one engineer quietly shipped something that broke the entire model. In 2026, most people are paying monthly for AI. Justine Tunney built an AI that runs from a single file. Download it. Double-click it. Start chatting. No installation. No cloud. No internet. No subscription. It's called llamafile. One executable bundles everything: • Model weights • Inference engine • Chat interface • Local web server • OpenAI-compatible API She even wrote 84 optimized CPU kernels, making local AI dramatically faster—even on hardware like the Raspberry Pi 5. The project returned stronger than ever in 2026 with: → GPU support → Multimodal input → Terminal UI → whisperfile for offline speech-to-text Over 25K GitHub stars. Apache 2.0. Runs open models from 0.6B to 27B parameters. While everyone else is renting AI... This project reminds us that sometimes the best software is the one you own. Open source keeps winning. Repo👇

Dario just declared war on open-source. Anthropic's message is clear: open source could destroy the entire AI business model, and Chinese open-source models are the cause. I sat down with @jasonlk & @rodriscoll to discuss it, along with the biggest news in tech this week: - Anthropic & Dario Declare War on Open-Source - Coinbase Slashes AI Spend 50%: Is the Token Bubble Bursting? - Kalshi's $40BN Valuation & Impending IPO - Bending Spoons: The Smartest IPO of 2026 & the $100BN SaaS Roll-Up Play My notes below: 1. Anthropic Is Laying the Foundation for a Deal With the U.S. Government on Chinese Models Anthropic accused Chinese open-source AI competitors of “brazen theft” through model distillation that violates its terms of service. Rory noted the hypocrisy, given that U.S. frontier models originally scraped external IP. Still, Anthropic appears to be laying the groundwork for a regulatory trade: complying with domestic access restrictions in exchange for a federal ban on distilled Chinese models. 2. Jason Lemkin’s Response to Brian Armstrong’s AI Tweet Jason dismissed Coinbase CEO Brian Armstrong’s 50% LLM cost-cutting post as “performative social media,” arguing that savings matter little if core revenue is flat or shrinking. He believes AI must actively drive top-line growth. Rory defended the move as “cost management 101,” saying cash-conscious enterprise executives will quickly emulate it to curb runaway frontier model fees. 3. CEOs Are Struggling to See the ROI From AI Massive enterprise spending on AI tokens is failing to deliver the expected revenue or productivity gains, leaving CFOs searching for measurable operational lift. Jason noted that adding millions in AI spend can still produce the same growth rates as prior quarters. Rory argued that AI spending must clearly accelerate software delivery or create definitive bottom-line savings as boards push back on reckless “token maxing.” 4. We Are All So Aligned in Wanting AI to Win Jason warned that the U.S. economy is structurally addicted to AI, with 40% of the S&P 500 tied to the boom, making society eager to prop it up to protect 401(k) portfolios. Rory countered that protectionism artificially inflates intelligence costs for the broader economy. He compared it to banning IBM PC clones in the 1980s just to protect IBM’s stock price, calling the blocking of low-cost open-source alternatives “fricking dumb.” 5. Bending Spoons and the New Playbook for B2B Revenue Arbitrage Bending Spoons’ $20 billion public valuation marks a shift toward tech roll-ups that drive profitability through price hikes and cost-cutting rather than organic user growth. Jason predicts this playbook will expand into mature B2B SaaS. By acquiring sticky but underperforming platforms like Marketo, Asana, or PagerDuty and injecting hungry talent, operators can rapidly improve retention and capture massive revenue arbitrage.

Stumbled across Everything Claude Code today and this might be one of the most ambitious open-source AI engineering repos I’ve seen in a while. Most repos give you prompts. Most frameworks give you agents. This thing feels like someone tried to package an entire AI engineering operating system 😭 - 30+ specialized agents - 60+ built-in skills - Planning, TDD, reviews, debugging, refactoring workflows - AgentShield security testing with 1,282 integrated tests - Memory systems, hooks, commands, orchestration setups - Support for Claude Code, Cursor, Codex CLI, OpenCode, etc. Getting value from coding agents isn’t just about using a stronger model. It’s about workflows, memory, delegation, context management, security, planning, and repeatable systems around the model. This repo is trying to solve exactly that. Definitely testing parts of it on future projects.

This is not another AI slop model. Don’t ignore GLM 5.2. I spent the last few hours testing it after a few smart friends told me I was sleeping on it. I was skeptical. I’m usually very cynical about open models because, in practice, most of them feel miles behind the frontier labs. Useful? Sure. Comparable? Not really. But this one felt different. I’m not saying it’s perfect. I didn’t run a full benchmark suite. But across writing, reasoning, coding, analysis, and messy real-world tasks, this is the first public open model that felt surprisingly close to something like Opus 4.6. That is a massive deal. It genuinely feels like a ChatGPT moment for public open models. The catch: running it properly is still expensive. Think something like 8 Nvidia H200s, roughly $400K to buy or around $20K/month to rent. Not cheap. But if you’re an enterprise spending millions a month on Anthropic/OpenAI, this is suddenly very interesting. Open models just became impossible to dismiss.

🚨 China considers BLOCKING external access to its top AI models. This is concerning for U.S. companies, as various frontier and highly specialized agentic AI use cases today rely on open-source AI models, often Chinese ones. The adolescence of AI policy is here, triggered by the release of Mythos and increased control over what gets out to the public. We might be entering a Cold War-like era of AI. My full article below.

I tested 10 open source AI tools this week. I didn't write a single line of code for any of them. I gave Codex the repo link, said install this, and it picked the folder, checked my disk space and opened the app when it was done. That's the actual story. The tools are just the proof. → OpenMontage, the first open source agentic video production system. One sentence in. It ran the research, went and found real footage, cut it into a timeline, graded it, then wrote and voiced its own narration on top. It was the #1 trending repo on GitHub the day it launched. → Voicebox, MIT licensed, built on Qwen3-TTS. Cloned my voice off a short sample in about a minute. This is what you're paying ElevenLabs for every month, except your voice never leaves your machine. → HyperFrames from HeyGen. Your agent writes HTML and CSS, Chrome and FFmpeg turn it into a deterministic MP4. I asked for liquid glass and chrome ribbons colliding in slow motion. What came back looks like a week of someone's life in After Effects. Apache 2.0, 32,000+ stars. → Nemotron 3 Ultra, NVIDIA's largest open model. 550B total, 55B active, with weights and training data and recipes all published. I pointed a coding agent at it and asked for an EMI calculator in one file. It built it, then reviewed its own output, caught a bug and rebuilt it before it showed me anything. Six more in the video, including a meeting notetaker that never sends your audio anywhere. Installing used to be the hard part. Now it's the part you delegate.

Sam Altman just said something that should worry you more than excite you: "AI is close to creating a genie that can grant any wish." This is EXACTLY why open-source AI matters - and this was Elon's original thesis when he was at OpenAI. Right now, the future of all AI power sits with a handful of companies. Think: OpenAI, Anthropic, Google, Meta. They decide who gets access, at what price, under what rules, and on what timeline. Open-weight models are the only solution to ensuring this "genius in a bottle" power is in check. Ultimately, this is also why it matters that NVIDIA, Microsoft, Hugging Face, and dozens of others just signed a joint letter arguing that we need to pivot towards open-weight AI. The most powerful technology in human history should not be something a handful of executives dole out to the world on their own terms. The bull case for open-source AI is simple: don't let five companies hold all the leverage over everyone else.

“don’t bet against AI models improving dramatically over time” used to be something you’d say in support of the frontier labs winning it all Equally interesting is this phrase applied to local / open weight models. They are getting better and faster dramatically too, just months behind the frontier It might be that frontier models won’t be needed for 90%+ of consumer/prosumer use cases. The arms race is for the remaining high-value 10% - coding, science, math, robotics. But by volume, everyone else will run on cheap open models

open-source AI must win at all costs and this week, we got two major open model releases: glm-5.2: latest open-source MoE model (744b total parameters, 40b active parameters) best for coding, reasoning, and agentic tasks with 1m-token context window kimi k2.7-code: open-weight coding/agentic MoE model (1t total parameters and 32b active parameters) focused on multimodal, long-horizon SWE tasks
@milesdeutscher ·
The future of AI is undoubtedly open-sourced. For 99% of people, the top open-weight models can already handle all your daily needs. Imo, the best thing you can do right now is run a "barbell" approach for your AI usage: Intial 10% and planning phase: Use frontier intelligence (Opus/GPT) Gruntwork and the middle 80%: Switch to open-weight model (GLM, Kimi) Final 10% and review: Switch back to froniter intelligence to verify Best of both worlds - cost efficiency + intelligence.

NVIDIA's Open Models in 1 Diagram You probably know NVIDIA as the company that sells GPUs. But it’s also the world’s largest publisher of open AI models (@NVIDIAAI), with a lineup that goes far beyond chatbots. We wanted to understand how a company best known for hardware builds so many high quality models, and why it gives them away for free. So we spoke with @ctnzr, VP of Applied Deep Learning Research at NVIDIA. He walked us through the full lineup and the ideas behind it, summarized in the diagram below. 1. Reasoning: Nemotron is NVIDIA's family of LLMs that think before they answer. The line started in 2023 and the current generation, Nemotron 3, is a hybrid + MoE model that comes in three sizes: Nano for fast simple tasks, Super for harder planning, and Ultra for the heaviest reasoning. 2. World models: Cosmos predicts the next state of the physical world, not the next word. Cosmos 3 is one omni-model that can generate plausible video of a scene, reason about what is happening, and predict what comes next. 3. Robotics: Isaac GROOT is the first open humanoid foundation model. GROOT 1.7 takes camera frames and an instruction in, and outputs motor commands in real time. Its reasoning core is Cosmos Reason. 4. Production: safety, speech, and vision models. These are the building blocks that make AI usable in real applications. 5. Specialized domains: BioNeMo for biology and drug discovery, Alpamayo for self-driving cars that explain each decision, NVIDIA Ising for quantum computing, and Earth-2 for weather and climate modeling. Read the full breakdown here: https://t.co/XQk33bNqCj

Just finished listening to latest @theallinpod which had a discussion on the “rant” by Alex Karp that went viral this week The biggest realization that everyone is waking up to is the *lack* of competitive edge when using frontier models If all your competitors use them, you have no differentiation Worse yet, using those models could subject you to competitive risk if the labs decide to take your data and make products that compete with you (just ask Figma) The crazy icing on the cake is that these models are 5-100x more expensive than alternatives that can be made just as good with the right implementation So not only do you lose differentiation, you pay heavily to lose it These are themes that those of us who have been proponents of open source AI have been saying for some time, glad to see it becoming more consensus But now the real challenge begins - in many ways using Anthropic or OpenAI is like pushing the easy button The products are great and they really work, and the new “deploycos” will happily embed them in your org so you don’t have to think to hard about how to use them But building sovereign AI with your data and open source models takes more skill, it’s not as easy Companies that make this easy for enterprises are going to do really well in the coming years

Two weeks ago Hugging Face got hacked by an autonomous AI agent. Their security team tried using an American AI model to investigate the attack. It refused. Safety filters couldn't tell a defender from an attacker. The only model that helped? An open-source Chinese one. That's what they used to run their forensics and figure out what happened. Now 26 of the most powerful companies in tech just signed a letter to Congress saying: do not ban open-weight AI models. NVIDIA. Microsoft. Meta. Dell. Palantir. Hugging Face. Y Combinator. a16z. IBM. CrowdStrike. Mistral. Mozilla. Replit. Perplexity. Jensen Huang wrote his first ever post on X to share this letter. Satya Nadella shared it from his personal account. Michael Dell co-signed it. You know who didn't sign? OpenAI and Anthropic. Both preparing massive IPOs. Both lobbying to restrict the open models that compete with theirs. Here's the core argument of the letter: Open-weight models are the ones anyone can download, run on their own servers, and modify. No subscription. No API bill. No lock-in. They cost $1-2 per million tokens. Closed US models cost $25-50 for the same work. If these get restricted, every American company pays 10-20x more for AI while the rest of the world uses them freely and builds faster. The letter says what most people aren't saying out loud: concentrating all AI behind 3-4 closed providers is itself a security risk. Fewer people finding bugs. Less competition. Higher prices. More single points of failure. Hugging Face already lived this. The closed model couldn't help them. The open one saved them. Open source didn't kill the software industry. It built the internet. The question is whether America learns that lesson again.

Enterprises will relentlessly cost-rationalize their AI stack. That is why the next wave may belong to open source. The entire open-source AI ecosystem could see a surge over the next 12–24 months: 1. Models: Mistral, DeepSeek, Moonshot become viable defaults 2. Inference: Groq, Together, Fireworks absorb growing volume 3. Deployment: Modal, Replicate power custom AI applications 4. Orchestration: Portkey, Maxim route traffic across a multi-model world 5. Observability: Langfuse, Braintrust help teams monitor AI systems 6. Dev tooling: LangChain, Instructor become critical infrastructure The first phase of AI rewarded model creators. The next phase may reward the picks-and-shovels powering an increasingly open AI stack.

Overleaf’s AI competitor is now open-source. Until now, writing LaTeX meant keeping 4 tabs open: One for the editor. One for ChatGPT. One for compile errors. One for Stack Overflow because LaTeX decided your table was a crime. Octree just shipped an open-source AI LaTeX editor that puts the whole workflow in one place. You write LaTeX in a Monaco-based editor, chat with Claude inside the workspace, and compile the final document to PDF without leaving the app. So instead of asking AI for LaTeX in one tab, copying it into another, breaking the formatting, then begging Google to explain the error… The AI sits next to the document and helps you build it directly. It can help generate sections, clean up equations, fix syntax, improve structure, and assist with technical writing while you are still inside the editor. The stack is built with Next.js, React, TypeScript, Supabase, Vercel AI SDK, Claude API, Monaco Editor, Stripe, Tailwind, and shadcn/ui. And it even includes a standalone AI agent server, which means the AI layer is not just a chatbot glued onto a text box. This matters because academic writing is not normal writing. It has citations, equations, figures, tables, formatting rules, compile errors, and final PDFs. A regular chatbot does not understand that workflow. Octree is trying to make the writing environment itself AI-native. Open-source. Self-hostable. Built for researchers, students, and technical writers. I shared the GitHub repo in the replies.

Open source model caught up very fast. Over 3 years, Arena data shows open models moved much closer: the top-20% gap shrank from 100–150 points to ~50 by late 2024. And since Jan 2025, both open & proprietary models improved in parallel.

OpenAI and Anthropic compete for every customer they've got. But this week, they just found the one thing they agree on: warning regulators about open-weight AI. Dario's argument is that open-weight is dangerous because once the weights are out, nobody can revoke access or patch the guardrails. Even a Trump adviser isn't buying it. David Sacks called this exact move what it is: regulatory capture. Safety framing that just happens to lock out every competitor who isn't already a $100B lab. Told you. As soon as the model stopped being the moat, the lobbyists became the business.

Open source had an insane last 3 days... Kimi released the biggest open source model ever. And now you can run a 27b local model 90% on your PHONE. First, the top end. Moonshot released Kimi K3 yesterday. It's 2.8 trillion parameters. Open weights come July 27, so soon you can download the whole thing. And it's not just big. It opened at number one on the Arena frontend coding leaderboard at 1,679, ahead of Fable 5 at 1,631 and GPT-5.6 Sol at 1,618. That's blind human voting on who builds a better frontend, and an open Chinese model just beat both. On overall performance Moonshot admits K3 still sits behind Fable, and a lot of the numbers are self reported until the weights are public. So it's not "better than Fable" across the board. it wins some, it trails on others. But look at the price… K3 runs about $3 in and $15 out per million tokens. Fable 5 is $10 and $50. So you're getting a model that trades blows with the frontier for roughly a third of the cost. Now to the local 27b model. A startup called PrismML took Qwen3.6 27B, the same model I run locally as my operator, and compressed it down to 3.9 gigabytes. Small enough to run on an iPhone. It keeps around 90% of the full model's performance in the 1 bit version and about 95% in the slightly bigger one. Completely free under Apache 2.0. A capable 27B model, running in your pocket, for nothing. Put those two together and you can see where this is going. Open models are trading blows with the best closed model on earth for a third of the price. And a real one now fits on a phone with no cloud behind it at all. The whole idea that you need a giant lab and a data center to touch this level of AI is falling apart on both ends at once.

What if I told you the most-starred AI agent framework might not be the best one? This new research analyzed the health of 15 major open-source AI agent frameworks over 3+ years using: • 808,042 GitHub stars • 73,997 pull requests • 86,241 commits • 987,330 GitHub profiles The findings challenge one of the biggest assumptions in open source. Here are the highlights: • AutoGPT gained 111K+ stars in a single month, but converted fewer than 9 contributors per 1,000 stars. • Pydantic-AI had far fewer stars, yet a much stronger contributor density—showing deeper real-world adoption. • LangChain attracted 82.5% of developers who contributed across multiple AI agent frameworks, making it the ecosystem's shared infrastructure. • The biggest contributor drop happens within the first 30 days. Projects that retain contributors beyond 90 days build much healthier communities. The authors argue that GitHub stars are a popularity metric—not an ecosystem metric. Instead, they recommend evaluating projects based on: • Contributor density • Cross-ecosystem engagement • Long-term contributor retention This is one of the most insightful studies on the AI agent ecosystem I've seen. It changes how we should evaluate open-source projects. Paper link👇
@adxtyahq ·
Why does Dario always disagree with open source? • "You can't see inside the model." - Open-weight models exist. • "Open source doesn't benefit from community contributions the same way." - Fine-tunes and quantizations prove otherwise. • "You'll have to use the cloud." - Plenty of models run locally. Am I missing something, or is he arguing against what open source looked like a few years ago?

seems likely AI evolves to become a banking-like industry the biggest labs achieve regulatory capture in the US Chinese open-weights models are blocked via some BS rules ("safety") maybe even KYC this could be the only way to achieve the revenue projections of American AI companies, which the entire US economy depends on at this point in that world, open source AI becomes the "crypto industry" of AI
@cyrilgupta ·
Jensen Huang shared a joint industry letter signed by NVIDIA and other leading tech companies on why open-weight AI models matter. Open models aren't just about transparency, they're about opportunity. For small business owners, they mean: • Lower AI costs • Faster innovation • Less dependence on a single vendor • The ability to build custom solutions without enterprise-sized budgets For SaaS founders and builders, open models unlock: • Faster product development • Greater flexibility to fine-tune models • Better control over performance, privacy, and deployment • More room to experiment without worrying about API pricing alone The next generation of successful businesses won't just use AI, they'll build unique products and workflows on top of it. Open models make that future accessible to everyone, not just the biggest tech companies. That's a win for innovation, competition, and entrepreneurship.

Open source AI is having a moment. And it's not happening by accident. Here's why: 1/ It's now clear you can get close to frontier-level performance while keeping a transparent training pipeline. Today's Inkling launch from @thinkymachines is another strong example. 2/ More well-funded teams are building open-weight models than ever before. With models like Grok, Cursor, Muse Spark and others entering the space, we're heading toward a much more diverse ecosystem for coding and AI agents. 3/ Companies want more control over their data. Many are willing to trade a bit of frontier performance in exchange for privacy, ownership and not helping train a future competitor. 4/ Open source gives you flexibility. Bring your own model, evaluation stack, business context or harness. You're not locked into a single vendor. 5/ The conversation inside companies has shifted. It's no longer "How do we get everyone using AI?" It's "Why is our AI bill growing faster than the value we're getting?" 6/ Geopolitics matters too. More countries are looking at open-weight models as the best way to deploy frontier-level AI inside secure, controlled environments. We're moving from a world dominated by a few models... to one with real choice.

"Open source AI reduces power concentration" - it depends on what you mean by power. Open-weight models are genuinely useful: Universities can experiment freely. Self-hosting protects you from surveillance and political dependence on US providers. Per Epoch AI, the capability gap is only ~3 months on average. That's real access. But access to comparable capabilities ≠ power over the trajectory. By default, three US labs will decide what gets built next, what safety measures exist and what capabilities to pursue or hold back. Open-sourcing weights lets you use frontier AI. It doesn't give you a seat at the table where the frontier is shaped. I wouldn't be surprised if, at some point, they concentrate on a double-digit percentage of the economy. Open source reduces dependency. It doesn't reduce the concentration of the power that actually matters: who decides where this goes.

Xiaomi MiMo-V2.5: Open-Source Model Focused on Efficiency and Long Context - Released under a clean MIT license, MiMo-V2.5-Pro is now tied with Moonshot’s Kimi K2.6 at the top of open-weights models (54 on the Artificial Analysis Intelligence Index) - Both Pro and base models support 1M token context, a major jump from the previous release - Leads open-weights on agent tasks (GDPval-AA 1578), ahead of DeepSeek V4 Pro and GLM-5.1 - Much more token-efficient: 92M output tokens vs 170M for Kimi K2.6, cutting inference cost nearly in half - Uses a 1T parameter MoE architecture (42B active) for strong performance with efficient compute - Around 75% non-hallucination rate, one of the better reliability ratios in open models - Day-one support via SGLang and vLLM, with optimizations for AWS and AMD hardware - Full FP8 needs 316GB VRAM, but lower-bit quants are expected to run on high-end local setups Feels like open-source models are moving toward long context, better efficiency, and real agent workflows, making self-hosting more practical over time.

“Open models don’t mean open AI.” @hstyagi Co-Founder @SentientAGI says: “You can build on open-source models, but the data, feedback, and iteration loop are still closed.” “The real gap isn’t just the model, it’s the entire development process.” “We want that whole evolution of software and agents to be open.” “Not just models competing, but the systems that build agents competing in the open.”

"The open-versus-closed debate in robotics isn't really about the models. It's about the data loop." — Samy Karim, founder of @cybernetic_lab Everyone imports the LLM frame: open weights vs closed weights, Llama vs GPT. Samy's point is that robotics isn't there yet. The training data barely exists. Teams are generating it right now, in simulation and through teleoperation, one task and one gripper at a time. So the real question isn't whether the model is open. It's whether the loop producing the data is open or closed. In robotics, that loop is already cracking open. Hugging Face's LeRobot is about a year old (it launched last summer) and it's already a hub: open hardware, open datasets, open model launches. @BitRobotNetwork put its Earth Rover hardware and the data it collects on there. Amanda, BitRobot's COO, runs what she calls an open robotics lab, pulling in contributors worldwide to collect data and evaluate models. On the eval side, platforms like RoboArena let you rank one model against another across environments, and both Nvidia and Physical Intelligence publish there. China has its own version, RoboChallenge. Samy's read: Chinese labs treat open-sourcing as a strategy, a way to build a moat and fundraise. So why does open have a shot here, when most frontier robotics work sits behind closed doors? Diversity. The labs want every kind of task, environment, and embodiment, and one warehouse is different enough from the next (different hardware, different grippers, different lighting) that no single company's data covers the space. That edge-case sprawl is exactly what a distributed network is built to collect. Then the part nobody mentions: you can't run these models out of the box. The post-training loop, fine-tuning the thing to actually work on a client's site, is where a deployment lives or dies. Open models make that loop workable for everyone, not just the lab that trained it. The closed loops are real. Tesla will have a great one for Optimus. China's data farms are running teleoperation at huge scale. But how much of that reaches anyone outside? So far, nothing. "It's the third time I've heard crypto is dead," Samy said about the broader gloom. "You can't kill what's already dead." Same logic on the data loop: it started about a year ago, and it isn't slowing down. Robotics Livestream EP3, watch it on YouTube below: https://t.co/kJmaWNeoIz

Three governments wrote new AI rules this month, and every one is chasing the same thing: what's actually happening inside the model. China's agent-specific regulations became enforceable July 15, the world's first dedicated legal category for AI agents. Illinois now requires third-party safety audits for enterprise AI systems. The European Commission published new transparency guidelines for AI providers and deployers on July 20. Every one of these rules is trying to force disclosure that open-weight models already give you by default: what's in the model, how it was trained, what it does when nobody's watching. Closed labs are about to spend a great deal of legal budget proving what open source proves for free.
@shawnchauhan1 ·
Open-source AI was supposed to democratize intelligence. Alibaba just reversed course on Qwen, its open-weight leader. A few months ago, releasing weights openly was a competitive signal - proof of confidence, a bid for developer loyalty. Now it is a liability. When compute is constrained and inference is expensive, giving away the model means giving away the margin. The open-source era of frontier AI may be shorter than anyone predicted.
@HarryStebbings ·
1. Should Chinese open models be banned? 2. Will Anthropic and OpenAI hit their targets in 2027? These are honestly the two biggest questions right now that we discuss in the only show you need to listen to every week with @jasonlk and @rodriscoll My notes below: 1. Why the 10x Price Cut of Chinese Open Models Is an Enterprise Security Trap Chinese open models like Kimi and Qwen are driving the search for cheaper intelligence. A 10x cost cut has pushed regulated enterprises to run more error-catching supervisor models, increasing token usage by 2.5x. But it also creates unprovable data export and leakage risks, leaving CIOs with a painful tradeoff between cost and security. 2. Why the Low-Cost, Open-Weight LLM Layer Is a Brutal Margin Trap for US Startups Massive valuations for Chinese open-weight models raise a hard question: is low-cost AI a good standalone business? US giants have left a vacuum for much cheaper intelligence, but much of the advantage comes from distillation, which faces legal hurdles in the US. That leaves providers exposed to brutal margin compression. 3. Why Turning Down a $6BN Acquisition Offer Is a Sucker Bet for Most Founders OpenRouter leaking sale talks at a $5 billion to $6 billion valuation is savvy as Ramp, Databricks, and others launch competing routing features. Private liquidity windows are rare, and exiting before a feature becomes commoditized is often optimal. Turning down life-changing cash only makes sense if a founder is certain they can build a 10x larger company. 4. Why Hypergrowth Inference Providers Must Vertically Integrate to Survive the CapEx Wars Fireworks hitting a $17.5 billion valuation shows the best AI investments are still in infrastructure. Massive developer demand has turned low-margin compute brokering into a strong business with mid-30s gross margins. To avoid commodification, hypergrowth inference providers must vertically integrate into their own data centers. 5. Why the Entire US Stock Market Is Held Hostage by the 2026 AI Growth Rate The tech ecosystem and hyperscaler CapEx trajectory depend on OpenAI and Anthropic’s growth rates into 2026. Frontier models face pricing pressure from cheap open-weight alternatives but remain trapped by real inference costs and massive training investments. If growth slows or forced price cuts erode margins, the market dislocation could be severe. 6. Why Stripe Swallowing PayPal Is a High-Stakes Bet on Legacy Tech Rationalization Stripe partnering with Advent to take PayPal private would show how attractive late-stage scale has become for capital deployment. While absorbing a legacy giant growing at 7% could slow Stripe’s standalone growth, it would instantly expand its processing footprint. The deal would mark a historic passing of the torch from legacy payments to the modern upstart.
