OpenClaw

OpenClaw is an open-source AI agent interface that connects to a model server to run tasks across your project. It speaks the Anthropic Messages API, which optiq serve exposes via /v1/messages.

1. Install OpenClaw

# macOS / Linux / WSL:
$ curl -fsSL https://openclaw.ai/install.sh | bash

# Windows PowerShell:
PS> iwr -useb https://openclaw.ai/install.ps1 | iex

# or, project-local via npm:
$ npm install openclaw

2. Start optiq serve

$ optiq serve \
    --model mlx-community/Qwen3.5-9B-OptiQ-4bit \
    --mtp --mtp-depth 2 \
    --port 8080

3. Configure OpenClaw

Drop this into ~/.openclaw/openclaw.json. If you already have other providers configured, add "mode": "merge" next to "providers" so OpenClaw splices OptiQ in without replacing them:

{
  "models": {
    "providers": {
      "optiq": {
        "baseUrl": "http://localhost:8080/v1",
        "apiKey": "sk-optiq-local",
        "api": "anthropic-messages",
        "models": [
          { "id": "qwen-9b", "name": "Qwen3.5-9B (OptiQ)" }
        ]
      }
    }
  }
}

Keys are camelCase (baseUrl, apiKey), api is "anthropic-messages", and models is an array (not a dict). The id is a short alias OpenClaw uses to address the model. optiq serve ignores the request body's model field and serves whatever you started it with. Validate with openclaw config validate after saving.

Sanity-check the wire with a one-shot:

$ openclaw capability model run --local \
    --model "optiq/qwen-9b" \
    --prompt "What is 2+2? Just the number."

Notes

• Same endpoint as Claude Code: both tools use /v1/messages. You can run both against the same optiq serve simultaneously.
• Tool use: Qwen/Llama-style <tool_call> blocks are translated to Anthropic tool_use blocks; OpenClaw's agent loop works on 9B+ models.
• Verified: tested against OpenClaw 2026.5.12 on macOS (Apple Silicon).
