Summary

OpenClaw rejects google-gemini-cli/gemini-3.1-pro-preview as an unknown model, even though Gemini CLI OAuth can select and run that model successfully on the same machine/account.

Environment

• OpenClaw: 2026.2.24
• Gateway runtime observed earlier in status: 2026.2.23 (after updates, still latest stable line)
• Provider path: google-gemini-cli (OAuth profile)
• Host: macOS

What works

• Direct Gemini CLI (gemini) can use gemini-3.1-pro-preview.
• In CLI model picker, the model appears and can be selected, and prompts run successfully.

What fails

When an OpenClaw agent model is set to:

• google-gemini-cli/gemini-3.1-pro-preview

OpenClaw fails before reply with:

• Unknown model: google-gemini-cli/gemini-3.1-pro-preview
• FailoverError: Unknown model: google-gemini-cli/gemini-3.1-pro-preview

Repro

1. Configure an agent model primary as google-gemini-cli/gemini-3.1-pro-preview.
2. Send a message to that agent.
3. Observe immediate failure and unknown model error.

Expected behavior

If Gemini CLI OAuth supports and can run gemini-3.1-pro-preview, OpenClaw should accept that model id for google-gemini-cli/* and route normally.

Temporary workaround

Use:

• google-gemini-cli/gemini-3-pro-preview (primary)
• google-gemini-cli/gemini-3-flash-preview (fallback)

Request

Please update OpenClaw's google-gemini-cli model registry/validation to include gemini-3.1-pro-preview (and ideally keep this list synchronized with Gemini CLI availability to avoid lag).
