Add support for Gemini 4 Argon #33
Description
Feature description
Add support for Google's new frontier model Gemini 4 Argon (gemini-4-argon / antigravity-gemini-4-argon) across the model registry, standalone CLI, and quota routing.
Use case
Gemini 4 Argon has been announced by Google for agentic coding and deep reasoning workflows. Wiring Argon into the Antigravity OAuth catalog enables users with access/quotas to route sessions to Argon via CLI, OpenCode, and Pi.
Proposed changes
- Add model definitions and aliases (
antigravity-gemini-4-argon,gemini-4-argon) inpackages/core/src/model-registry.ts. - Configure quota group routing and header styles.
- Surface in CLI catalog and host adapters.

It is not available for public use yet (so it cannot be added). Please, do not use ai to write issues.

Antigravity does not currently offer a Gemini 4 Argon model; it is not in the server model catalog that the official Antigravity CLI receives. We add models once Antigravity serves them, so I'm closing this for now.
