Feature description

With the update of Antigravity to Opus-4.6, the current policy means that Ultra users can only use Opus-4.6, while Pro users can only use Opus-4.5. We hope to establish some kind of mapping or model management for individual accounts.

Use case

For example, when I specify which model to use for each agent through oh-my-opencode, opencode-antigravity-auth can switch between different models based on the account's capabilities.

👋 Thanks for opening this issue!

Valid enhancement request. Current behavior is account rotation by model family/quota, not per-account model capability mapping. Workaround: set model per agent in oh-my-opencode and use opencode auth login -> Manage accounts (enable/disable) for sessions needing specific models. Automatic Opus-only vs Pro-only account routing would require a new per-account model policy feature.

I'll keep that in mind, but not in scope for now, or if you want you can open a PR for this :)
