gpt-5.3-codex - tool regression via api
Resolved 💬 1 comment Opened Feb 25, 2026 by kalineh Closed Feb 25, 2026
gpt-5.3-codex seems to hallucinate that it has called tools, when it has not
same input/output on gpt-5.2-codex and gpt-5.2 and gpt-5.1-codex works fine
can repro locally but project too large/complicated to isolate
