Best Models for OpenClaw in 2026

The Best Primary Model

Claude Sonnet 4.6 is the consensus daily driver for OpenClaw. It handles email, calendar, research, and general queries without breaking the bank. It's fast enough for real-time chat and smart enough for multi-step tasks including browser automation and code execution. Set it with openclaw config set agents.defaults.model.primary 'anthropic/claude-sonnet-4-6'.

The Optimal Fallback Chain

A resilient setup uses at least 3 providers. Recommended chain: Claude Sonnet 4.6 (primary) → Gemini 2.0 Flash → GPT-5-mini → Gemini 2.5 Flash Preview → DeepSeek. Strong models up front, budget fallback at the end.

Budget Models

For cost-sensitive setups: GPT-4o-mini and Gemini Flash are excellent budget options. DeepSeek V3 offers strong reasoning at a fraction of the cost. These work well as fallbacks and for simple tasks.

Models to Avoid

GPT-4o has been superseded by the GPT-5 family for tool safety. OpenClaw's security audit may flag it. If you're running an older config with GPT-4o, consider replacing it with GPT-5-mini or dropping it from your fallback chain entirely.

How to Switch Models

Change your primary: openclaw config set agents.defaults.model.primary 'model-name'. Add fallbacks: openclaw models fallbacks add model-name. Check your chain: openclaw models status. Always restart the gateway after changes: openclaw gateway restart.
