About
AI Release Tracker is one timeline of every notable model release from all the major AI labs. It records who shipped what, when, and how it scored at the time.
Why it started
The site went up on November 30, 2025: three years to the day after ChatGPT was released and set this pace. By that anniversary the labs were shipping faster than anyone could follow, and Peter Assentorp had a bad case of release FOMO. A flagship would land on a Tuesday, the discourse would move on by Thursday, and you would hear about it a week later from a screenshot.
The fix was a single page that answers the question directly: what came out, from whom, and how does it compare to the thing it replaced, with no feed to scroll through. That page became this site.
