## Node-local inference

Agents can delegate a short task to an Ollama model on a paired desktop or
server node. The prompt and response cross the existing authenticated
Gateway/node connection; the request runs on the node's own loopback Ollama
endpoint (`http://127.0.0.1:11434`).

<Steps>
  <Step title="Start Ollama on the node">
    ```bash
    ollama pull qwen3:0.6b
    ollama list
    ```
  </Step>
  <Step title="Connect the node host">
    ```bash
    openclaw node run \
      --host <gateway-host> \
      --port 18789 \
      --display-name "Local inference"
    ```

    Approve the device and its node commands on the Gateway host, then verify:

    ```bash
    openclaw devices list
    openclaw devices approve <deviceRequestId>
    openclaw nodes pending
    openclaw nodes approve <nodeRequestId>
    openclaw nodes status --connected
    ```

    A first connection, or an upgrade that adds Ollama commands, can trigger
    node-command approval. If the node connects without advertising
    `ollama.models` and `ollama.chat`, check `openclaw nodes pending` again.

  </Step>
  <Step title="Use it from an agent">
    The bundled Ollama plugin exposes the `node_inference` tool. Agents call
    `action: "discover"` first, then `action: "run"` with a node and model from
    that result (`run` can omit the node when exactly one capable node is
    connected). For example: "Discover the Ollama models on my nodes, then use
    the fastest loaded model to summarize this text."
  </Step>
</Steps>

Discovery reads `/api/tags`, checks `/api/show` capabilities, and uses
`/api/ps` when available to rank already-loaded models first. It returns only
local models Ollama reports as chat-capable (`completion` capability) —
Ollama Cloud rows and embedding-only models are excluded. Each run disables
model thinking and defaults output to 512 tokens (hard cap 8192) unless the
tool call requests a different `maxTokens`; some models (for example GPT-OSS)
do not support disabling thinking and may still emit reasoning tokens.

To keep Ollama running on a node without exposing it to agents:

```bash
openclaw config set plugins.entries.ollama.config.nodeInference.enabled false
```

Restart the node (`openclaw node restart`, or stop/rerun `openclaw node run`
for a foreground session). The node stops advertising `ollama.models` and
`ollama.chat`; Ollama itself and the Gateway's Ollama provider are unaffected.
Set the value back to `true` and restart to re-enable; a changed command
surface may need `openclaw nodes pending` approval again after reconnect.

Verify the node commands directly, without an agent turn:

```bash
openclaw nodes invoke \
  --node "Local inference" \
  --command ollama.models \
  --params '{}' \
  --invoke-timeout 90000 \
  --timeout 100000

openclaw nodes invoke \
  --node "Local inference" \
  --command ollama.chat \
  --params '{"model":"qwen3:0.6b","prompt":"Reply with exactly: pong","maxTokens":32,"timeoutMs":120000}' \
  --invoke-timeout 130000 \
  --timeout 140000
```

`--invoke-timeout` bounds how long the node has to run the command;
`--timeout` bounds the overall Gateway call and should be larger.

Node-local inference always uses the node's own loopback endpoint — it does
not reuse a configured remote/cloud `models.providers.ollama.baseUrl`. The
node commands are available by default on macOS, Linux, and Windows node
hosts and remain subject to normal node pairing/command policy.
