Discovery skipped Antigravity's gemini-4-carbon-high and gemini-3.8-flash-high, because Pi has no metadata under those IDs. They now resolve to google/gemini-4-carbon and google/gemini-3.8-flash, as gemini-4-argon-high resolves to google/gemini-4-argon. Requests keep the advertised -high ID, and explicit aliases and exact metadata still take precedence.

CLIProxyAPI 8.0.65 added gemini-4-carbon-high. Pi 1.5.2 bundles gemini-3.8-flash but not gemini-4-carbon. Carbon's metadata comes from Pi's pi.dev catalog, which Pi downloads only while Google has credentials in Pi. Without that catalog, gemini-4-carbon-high registers once a Pi release bundles Gemini 4 Carbon. The extension keeps skipping IDs that have no Pi metadata and carries no model metadata of its own.

The extension now targets CLIProxyAPI 8.0.67. Releases 8.0.65 to 8.0.67 need no other source changes. The model list format, model_cooldown errors, media and management routes, and the Claude Code user agent that the quota lookup sends are unchanged.

Confidence Score: 5/5

The PR appears safe to merge; no blocking issues were found.

Summary

Adds metadata fallbacks for gemini-4-carbon-high and gemini-3.8-flash-high while keeping the advertised request IDs.

• Antigravity discovery now recognizes Carbon and Flash high IDs.

Summary

Summary by CodeRabbit

• New Features
  • Added support for resolving the Antigravity model IDs gemini-4-carbon-high and gemini-3.8-flash-high to their corresponding Google models. Carbon registration requires Pi’s refreshed catalog to include its metadata.
• Compatibility
  • Updated the documented targets to Pi 1.5.2 and CLIProxyAPI 8.0.67.
• Release
  • Updated the package version to 0.3.9.

Changes

The package version changes to 0.3.9. The catalog adds metadata fallback aliases for two Antigravity model IDs, and provider tests cover those IDs. The changelog records the release targets, and a comment updates the CLIProxyAPI version reference.

Antigravity model metadata and release

Layer / File(s)	Summary
Model fallback mappings and test coverage src/catalog.ts, test/provider.test.ts	The metadata fallback map adds aliases for gemini-4-carbon-high and gemini-3.8-flash-high. The provider test supplies Carbon metadata and adds gemini-4-carbon and gemini-3.8-flash to its canonical-ID cases.
Release version and compatibility notes package.json, CHANGELOG.md, src/claude-quota.ts	The package version changes to 0.3.9. The changelog records the release targets and model registration details. A comment updates the CLIProxyAPI reference from 8.0.64 to 8.0.67; the request header remains unchanged.

Merge Risk: Low · up to 811df

Users who run only through the proxy and have no Google setup will not see the new Carbon model, although the proxy advertises it. Other models, including the Flash mapping, are unaffected. The release can ship with this limitation documented, or Carbon metadata can be supplied without Google credentials first.

- Line 315: Make verified metadata for gemini-4-carbon-high available
independently of Google credentials or catalog refresh, so proxy-only discovery
can resolve the advertised model through google/gemini-4-carbon. Add a test for
the no-Google-configuration, no-cached-catalog installation path that does not
