Frequently Asked Questions
What's the best completely free LLM API?
For capability, Google Gemini 2.0 Flash free tier is excellent at 60 requests/minute. For speed, Groq offers ultra-fast inference on Llama models. For variety, OpenRouter provides free access to multiple models including Llama 3.3 70B.
Can I use free LLM APIs with OpenClaw?
Yes. OpenClaw supports any OpenAI-compatible API. You can use Ollama for completely free local models, or configure OpenRouter, Groq, or Gemini for cloud access without cost.
Are free LLM APIs good enough for production?
For low-traffic applications, yes. But rate limits make them unsuitable for high-volume production use. Consider paid tiers or self-hosting for production workloads.

Claude doesn't have a free API tier, but new accounts get $5 in free credits. You can also use Claude through the free claude.ai chat interface for personal use, just not via API.
