OpenAI reduces Codex Model Context Size from 372k to 272k

What we can confirm so far.

What we know

The merged pull request is titled “Backport refreshed bundled model metadata to 0.144” and touches a single .json file (+64 −54). The diff did not render for us, so we could not independently confirm the widely-reported 372k → 272k context-size change; that figure comes from community reading of the metadata, not from an OpenAI statement. Treat the specific numbers as unconfirmed.
