Best AI Models for OpenClaw: Complete Comparison Guide (2026)
Quick Answer: The best AI model for OpenClaw depends on your use case. For business automation, Claude Sonnet 4.5 via Anthropic API offers the best balance of intelligence and cost (~$3/MTok input). For zero-cost local operation, Qwen 2.5 7B via Ollama runs on 8GB RAM. For budget cloud usage, DeepSeek V3 offers near-GPT-4 quality at 90% lower cost.
This guide compares every major model option for OpenClaw — cloud APIs, local LLMs, and free tiers — with pricing, quality ratings, and configuration instructions.

How to Configure Models in OpenClaw
OpenClaw is model-agnostic. Switching models is a configuration change — no code edits required.
Provider Configuration in openclaw.json
Set your model provider and API credentials in the openclaw.json configuration file. OpenClaw supports Anthropic, OpenAI, Ollama, OpenRouter, and any OpenAI-compatible endpoint.
- Set 'provider' to your chosen provider (anthropic, openai, ollama, openrouter)
- Set 'model' to the specific model name (e.g., claude-sonnet-4-5, gpt-4o, qwen2.5:7b)
- Add your API key for cloud providers (ANTHROPIC_API_KEY, OPENAI_API_KEY)
- For Ollama, set 'apiBaseUrl' to http://localhost:11434 — no API key needed
- Restart OpenClaw after changing the configuration
Fallback Chains: Primary + Backup Models
OpenClaw's Gateway supports fallback chains — if your primary model fails or is unavailable, it automatically routes to the next provider in the chain. This ensures your automations never break.
- Configure multiple providers in the gateway.providers array
- Primary model handles most requests (e.g., Ollama for free, or DeepSeek for cheap)
- Fallback activates automatically on timeout, error, or rate limit
- Example: Ollama (free) → DeepSeek V3 (cheap) → Claude Sonnet (premium)
- Each provider can have independent timeout and retry settings
- Gateway logs which provider handled each request for cost tracking
