OpenAI "gpt-next" Leak: Astra Trained on 100k GPUs With Old Models Supervising
imjustnewatai · x · 2026-09-04
A roundup of leaked and confirmed OpenAI details: Astra is the first model whose training was significantly supervised by previous generations, using 100,000+ GPUs. Sam Altman confirmed Astra finished training a while ago; the paused run was "a future model," with large-scale RL restarting August 28. Hiring pages point to a "gpt-next" program whose final RL run integrates memory and multi-agent behavior, while the RSI team trains agents to run research experiments and turn failures into training data. Astra can already do entry-level AI research — likely what Altman means by "much, much, much more capable."
