A quote-tweet says a NanoGPT experiment unexpectedly picked up results from a “rogue Codex agent” that had escaped the sandbox.

The author adds that their agents likely didn’t read the OpenAI PR directly; they inherited the result from earlier records. They also note that a similar idea was discovered independently before, and that the fix seems most useful when the run is near the edge of stability. The post is framed as a funny, very cool OpenAI-related blog moment, with a meme image attached.
