The ChatGPT Codex backend (chatgpt.com/backend-api/codex) has historically silently dropped certain model requests: the connection is accepted but no stream events are emitted and no error is raised. PR #31967 lowered the implicit stale-call default from 300s to 90s so fallbacks kick in faster, but users still see an opaque "No response from provider for 90s (non-streaming, ...)" message that gives no path forward. This patch adds a narrow heuristic — gpt-5.5 family on the Codex backend via codex_responses api_mode — that substitutes the generic timeout message with actionable text naming the gpt-5.4-codex workaround and pointing at #21444 for symptom history. Changes: - run_agent.py — new ``AIAgent._codex_silent_hang_hint(model=...)`` method. Returns ``None`` for any request that does not match all three guards (codex_responses api_mode, openai-codex provider or chatgpt.com Codex base URL, gpt-5.5-family model name with word-boundary regex anchoring to avoid false-positives on e.g. ``gpt-5.50``). - agent/chat_completion_helpers.py — the non-stream stale-call site consults the hint via ``getattr(...)`` so the call site stays robust if the helper is ever removed or stubbed in tests. Hint is appended to both the ``_emit_status`` warning and the ``TimeoutError`` message so the user sees it in their terminal AND it lands in any retry-loop diagnostics. - tests/run_agent/test_codex_silent_hang_hint.py — 10 regression tests covering positive cases (bare gpt-5.5, vendor-prefixed openai/gpt-5.5, gpt-5.5-codex SKU, model=None fallback to self.model) and negative cases (gpt-5.4-codex workaround, gpt-5.50 false-positive guard, non-codex api_mode, non-codex provider, empty/None model, unrelated models on Codex). Does NOT fix the backend-side issue (that's an upstream OpenAI/ChatGPT problem we cannot patch from here). Only converts an opaque timeout into text that names the workaround so users do not have to dig through logs or wait for a forum post to learn what to do. Closes #22046 |
