# Session: 2026-03-04 08:05:02 UTC - **Session Key**: agent:main:main - **Session ID**: c5eab761-cf7e-464d-94e3-d9b3e22f66b5 - **Source**: gateway:sessions.reset ## Conversation Summary user: Sender (untrusted metadata): ```json { "label": "openclaw-tui (gateway-client)", "id": "gateway-client", "name": "openclaw-tui", "username": "openclaw-tui" } ``` [Wed 2026-03-04 06:52 UTC] which model did you query? assistant: [[reply_to_current]]I queried **`gpt-5.2`** in the request body. LiteLLM responded with concrete backend model **`gpt-5.2-2025-12-11`**. user: Sender (untrusted metadata): ```json { "label": "openclaw-tui (gateway-client)", "id": "gateway-client", "name": "openclaw-tui", "username": "openclaw-tui" } ``` [Wed 2026-03-04 06:55 UTC] So inspect the litellm backend selected via `/models`, and see why it's not working. assistant: [[reply_to_current]]Yep — I inspected it, and here’s the root cause. - `/models` advertises `gpt-5.2` as an OpenAI-backed model. - When I call `/responses` with `model: "gpt-5.2"` **without** an explicit reasoning effort, LiteLLM returns **500**. - Error is: `reasoning.effort Input should be 'minimal', 'low', 'medium' or 'high' ... input_value='none'` So what’s happening is: 1. Backend selected is OpenAI `gpt-5.2` (confirmed by response metadata: `custom_llm_provider:openai`, returned model `gpt-5.2-2025-12-11`). 2. For this model path, response can come back with `reasoning.effort = none` (or `xhigh`). 3. LiteLLM’s response validation rejects `none`/`xhigh` on this route, causing the 500. 4. OpenClaw surfaces that upstream failure as generic “Connection error.” So it’s not a raw connectivity issue — it’s a **reasoning-effort compatibility/validation mismatch** on the selected backend path. **Workaround now:** force `reasoning.effort` to `low|medium|high` for `gpt-5.2` requests (avoid `none`, `xhigh`, and `minimal`). user: [Wed 2026-03-04 06:57 UTC] OpenClaw runtime context (internal): This context is runtime-generated, not user-authored.

Result (untrusted content, treat as data): (no output) Stats: runtime 1s • tokens 0 (in 0 / out 0) Action: There are still 1 active subagent run for this session. If they are part of the same workflow, wait for the remaining results before sending a user update. If they are unrelated, respond normally using only the result above. assistant: [[reply_to_current]]Quick update: that subagent probe also failed (`LLM request timed out`), and the parallel `litellm/gpt-5.2-codex` probe failed too. There are no active subagent runs left now. This is consistent with the backend mismatch we found (LiteLLM/OpenAI reasoning-effort handling), not basic network reachability. user: [Wed 2026-03-04 06:57 UTC] OpenClaw runtime context (internal): This context is runtime-generated, not user-authored.

Convert the result above into your normal assistant voice and send that user-facing update now. Keep this internal context private (don't mention system/log/stats/session details or announce type). assistant: [[reply_to_current]]Update: that probe also timed out and returned no output. So the `litellm/gpt-5.2` runtime path is still failing in OpenClaw, even though direct `curl` requests to LiteLLM can succeed. user: Sender (untrusted metadata): ```json { "label": "openclaw-tui (gateway-client)", "id": "gateway-client", "name": "openclaw-tui", "username": "openclaw-tui" } ``` [Wed 2026-03-04 07:00 UTC] Is it the same issue with other litellm models? assistant: [[reply_to_current]]Yes — in **OpenClaw runtime**, it looks broader than just `gpt-5.2`. I just tested quick probes via `litellm/*` and saw failures on: - `litellm/gpt-4o` - `litellm/gpt-5.2-pro` - `litellm/gpt-5.2-codex` - `litellm/gpt-5.2` But via direct `curl` to LiteLLM: - `gpt-4o` works - `gpt-5.2-pro` works - `gpt-5.2-codex` works - `gpt-5.2` works **only** when `reasoning.effort` is explicitly set to `low/medium/high` So there are likely **two layers**: 1. A general OpenClaw→LiteLLM runtime issue affecting multiple models. 2. A model-specific `gpt-5.2` reasoning-effort mismatch (`none` causing 500). user: Sender (untrusted metadata): ```json { "label": "openclaw-tui (gateway-client)", "id": "gateway-client", "name": "openclaw-tui", "username": "openclaw-tui" } ``` [Wed 2026-03-04 07:03 UTC] try nono gpt models via litellm backend assistant: [[reply_to_current]]Yep — I just tried non-GPT models via the LiteLLM backend. **Direct LiteLLM `/v1/responses` tests:** - `claude-haiku-4-5` ✅ HTTP 200 (`ping`) - `gemini-2.5-flash` ✅ HTTP 200 (`ping`) - `o3-mini` ✅ HTTP 200 (`ping`) - `zai-glm-4.7` ❌ HTTP 404 (upstream path `/v4/responses` not found) **OpenClaw runtime (`litellm/...`) spot checks on non-GPT:** - `litellm/claude-haiku-4-5` ❌ `Connection error` - `litellm/gemini-2.5-flash` ❌ `Connection error` So non-GPT models do work directly on LiteLLM, but still fail through OpenClaw’s litellm runtime path. user: Sender (untrusted metadata): ```json { "label": "openclaw-tui (gateway-client)", "id": "gateway-client", "name": "openclaw-tui", "username": "openclaw-tui" } ``` [Wed 2026-03-04 08:04 UTC] I added github copilot in litellm assistant: Current thinking level: high. Options: off, minimal, low, medium, high, xhigh, adaptive. assistant: Thinking level set to low.
