Evidence from codex-tui.log:
TUI logs show model selection:

2026-02-06T22:19:50Z INFO ... Selected model: gpt-5.3-codex, Selected effort: xhigh
2026-02-06T23:18:11Z INFO ... Selected model: gpt-5.3-codex, Selected effort: xhigh
2026-02-09T01:49:38Z INFO ... Selected model: gpt-5.3-codex, Selected effort: xhigh

But SSE response.model never uses gpt-5.3-codex.
Full log scan of response.model:

43x gpt-5.1-codex-mini
6x gpt-5.2-2025-12-11
0x gpt-5.3-codex

Thanks for providing the logs. I don't see any evidence of gpt-5.1-codex-mini being used. All SSE responses in the log are reporting responses from "gpt-5.3-codex", which is what was selected.

If you are seeing responses from gpt-5.2-2025-12-11, that is explained here.

Ok, thanks, it seems this has already been fixed.
