From 4.1M views on @omarsar0's original posts in the last 30 days.

Rewards eligibility: likely

Rough estimate. X publishes no payout rate, so this assumes about $5–12 per 1M original-post impressions from reported creator payouts. Only Premium viewers’ impressions count, so real payouts can be much lower.

    Crazy how good this is. I like the idea of making AI more collaborative. Kylon Annotations made this short clip of me. The paper stacks are accurate. 😅 It's very collaborative and lets a team analyze, annotate, and remix a video together.
