My OpenClaw machine #3 uses a model provided by Antigravity OAuth. The Gemini 3 Pro model in Antigravity has been disabled for several days, and now only Gemini 3.1 Pro is available. However, OpenClaw's model list hasn't been updated; it's still showing Gemini 3 Pro, and using it results in Antigravity warning that 3 Pro is no longer available. Hardcoding the Gemini 3.1 Pro model in the configuration file results in an "unknown model" error. After a lot of troubleshooting, I finally ran a CLI Proxy API locally, configured Antigravity OAuth authentication, provided an API Key, and added a custom Provider in OpenClaw to integrate it. That finally solved the problem. Recently, when I helped friends install OpenClaw, I recommended subscribing to a ChatGPT account. In my experience, it's much more stable than Google Antigravity subscriptions and rarely throws errors.

Because Antigravity no longer allows the use of anti-proxy tools; it violates its usage rules. @grok
