     - Proxy-style OpenAI-compatible routes also skip native OpenAI-only request shaping: no `service_tier`, no Responses `store`, no Completions `store`, no prompt-cache hints, no OpenAI reasoning-compat payload shaping, and no hidden OpenClaw attribution headers.
     - For OpenAI-compatible Completions proxies that need vendor-specific fields, set `agents.defaults.models["provider/model"].params.extra_body` (or `extraBody`) to merge extra JSON into the outbound request body.
     - For vLLM chat-template controls, set `agents.defaults.models["provider/model"].params.chat_template_kwargs`. OpenClaw automatically sends `enable_thinking: false` and `force_nonempty_content: true` for `vllm/nemotron-3-*` when the session thinking level is off.
+    - For slow local models or remote LAN/tailnet hosts, set `models.providers.<id>.timeoutSeconds`. This extends provider model HTTP request handling, including connect, headers, body streaming, and the total guarded-fetch abort, without increasing the whole agent runtime timeout.
     - If `baseUrl` is empty/omitted, OpenClaw keeps the default OpenAI behavior (which resolves to `api.openai.com`).
     - For safety, an explicit `compat.supportsDeveloperRole: true` is still overridden on non-native `openai-completions` endpoints.

 Keep `models.mode: "merge"` so hosted models stay available as fallbacks.
+Use `models.providers.<id>.timeoutSeconds` for slow local or remote model
+servers before raising `agents.defaults.timeoutSeconds`. The provider timeout
+applies only to model HTTP requests, including connect, headers, body streaming,
+and the total guarded-fetch abort.
