Change OpenClaw Agent Model on Clawdbot

Option 1 (recommended): Change the agent default via CLI

1. Set the primary model:

   
   openclaw config set agents.defaults.model.primary "anthropic/claude-opus-4-5"
   openclaw config set agents.defaults.model.secondary "anthropic/claude-3-5-haiku-latest"
   
   openclaw doctor --fix
         

2. Restart the gateway:

   
   openclaw gateway
         

3. Confirm in logs you see:

   
   [gateway] agent model: anthropic/claude-opus-4-5
         

Verify

• Run:

  
  openclaw doctor
        

• Or watch startup logs for:

  
  [gateway] agent model: anthropic/claude-opus-4-5
        

Important Note

• You must have anthropic/claude-opus-4-5 enabled on your Anthropic account. Otherwise you may see 403 or model-not-allowed errors.
• If that happens, it’s an Anthropic permissions issue, not an OpenClaw config issue.

Optional Next Steps

• Set per-channel models
• Configure fallback models
• Run multiple agents with different models
• Hot-swap models (where supported) without restarting
