Frequently Asked Questions

Which model is the cheapest to run with OpenClaw?
DeepSeek V3.2 at $0.28/$1.10 per million tokens (input/output) is the cheapest capable model — sessions cost roughly $0.02. Gemini 2.5 Flash ($0.15/$0.60) is even cheaper for simpler tasks but less reliable at complex tool calling.
Can I use a free model with OpenClaw?
Yes. Gemini offers a free tier for most models, and Llama 4 weights are free to self-host. You can also use Groq's free tier for Llama at ~$0.11 per million input tokens. See our [OpenClaw tutorial](/blog/openclaw-tutorial/) for setup instructions.
Does OpenClaw work with local models?
Yes. OpenClaw supports any OpenAI-compatible API, so you can point it at Ollama, LM Studio, or vLLM running Llama 4, Qwen, or Mistral locally. Expect slower responses and weaker tool calling compared to cloud APIs.
Should I use the same model for every OpenClaw task?
No. The smartest setup is model routing — use a cheap model (DeepSeek, Gemini Flash) for simple queries and escalate to Claude or GPT for complex multi-step tasks. OpenClaw's multi-model support makes this easy.
Which model has the best tool calling for OpenClaw?
Claude Sonnet 4.6 leads the PinchBench OpenClaw benchmark at 86.9% success rate and scores highest on MCP-based benchmarks (71.6 on MCPAgentBench). GPT-5.4 is close at 86.0% on PinchBench. For OpenClaw specifically, Claude and GPT are the safest choices for complex workflows.
