Gemini CLI

Not usable: Gemini CLI speaks only Google's Gemini API, which Kano Proxy does not serve.

There is nothing to set up, with the CLI or by hand.

Use Gemini models another way

1. Connect Antigravity on the Providers page.
2. Call antigravity/gemini-3-flash or another Antigravity id from your Models page, from any other tool on this list, for example Claude Code or OpenCode. The id is an example.

Limits

• Gemini CLI has no OpenAI- or Anthropic-compatible provider.
• Its only endpoint overrides, GOOGLE_GEMINI_BASE_URL and GOOGLE_VERTEX_BASE_URL, still send Gemini-format requests (generateContent and streamGenerateContent) with Gemini model names.

What would change this

The proxy would have to expose a Gemini-format API under /v1beta/models/<model>:streamGenerateContent. That is not planned. Gemini CLI's gateway path also has open bugs of its own, so even then the pairing would be fragile.
