Selecting gpt-5.3-codex in Codex shows response.model = gpt-5.2-2025-12-11 #10953
Description
What version of Codex CLI is running?
codex-cli 0.98.0
What subscription do you have?
Pro
Which model were you using?
gpt-5.3-codex
What platform is your computer?
Darwin 24.1.0 arm64 arm
What terminal emulator and version are you using (if applicable)?
Terminal.app
What issue are you seeing?
When I select gpt-5.3-codex in Codex, the returned Responses API object reports a different model: gpt-5.2-2025-12-11.
Log evidence (PII redacted) from ~/.codex/log/codex-tui.log:
2026-02-05T21:02:42.597590Z INFO codex_tui::chatwidget: Selected model: gpt-5.3-codex, Selected effort: xhigh
2026-02-06T21:34:23.110590Z TRACE codex_api::sse::responses: SSE event: {"type":"response.completed","response":{"model":"gpt-5.2-2025-12-11", ...}}
What steps can reproduce the bug?
- Run Codex with SSE tracing enabled:
RUST_LOG='codex_tui::chatwidget=info,codex_api::sse::responses=trace' codex - In the model picker, select
gpt-5.3-codex(effortxhigh). - Send any prompt (e.g. “hello”).
- Inspect
~/.codex/log/codex-tui.logand find theresponse.completedSSE event; observeresponse.modelisgpt-5.2-2025-12-11.
What is the expected behavior?
If I choose gpt-5.3-codex, I expect response.model reflects gpt-5.3-codex.

Have you continued to see this problem, or was this a one-time issue?
UniverseFly commentedon Feb 8, 2026
Yes, the issue still existed in my try just now. Is there a way to verify which model is routed for inference in the backend? My guess is either incorrect routing (the underlying model isn't
gpt-5.3-codex) or a less severe missing mapping that triggers a fallback model name in the final response (the underlying model is stillgpt-5.3-codex).theBucky commentedon Feb 9, 2026
