When you set `OLLAMA_API_KEY` (or an auth profile) and **do not** define `models.providers.ollama` or another custom remote provider with `api: "ollama"`, OpenClaw discovers models from the local Ollama instance at `http://127.0.0.1:11434`.
| Behavior | Detail |
| -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Catalog query | Queries `/api/tags` |
| Capability detection | Uses best-effort `/api/show` lookups to read `contextWindow`, expanded `num_ctx` Modelfile parameters, and capabilities including vision/tools |
| Vision models | Models with a `vision` capability reported by `/api/show` are marked as image-capable (`input: ["text", "image"]`), so OpenClaw auto-injects images into the prompt |
| Reasoning detection | Marks `reasoning` with a model-name heuristic (`r1`, `reasoning`, `think`) |
| Token limits | Sets `maxTokens` to the default Ollama max-token cap used by OpenClaw |
| Costs | Sets all costs to `0` |

This avoids manual model entries while keeping the catalog aligned with the local Ollama instance. You can use a full ref such as `ollama/<pulled-model>:latest` in local `infer model run`; OpenClaw resolves that installed model from Ollama's live catalog without requiring a hand-written `models.json` entry.

For native Ollama models, OpenClaw forwards thinking control as Ollama expects it: top-level `think`, not `options.think`.
For native Ollama models, OpenClaw forwards thinking control as Ollama expects it: top-level `think`, not `options.think`. Auto-discovered models whose `/api/show` response includes the `thinking` capability expose `/think low`, `/think medium`, `/think high`, and `/think max`; non-thinking models expose only `/think off`.
