Initial Analysis Report

Summary: This issue is a feature request to add support for the newly released Claude Opus 4.6 model in the Google Antigravity provider.
Issue Validation: Confirmed.
Reproducibility Assessment: Not applicable (Feature Request).
Root Cause Analysis: The proxy currently lacks definitions and mappings for claude-opus-4.6. Based on the existing implementation for claude-opus-4.5, the new model requires explicit inclusion in the available models list, alias mappings (to handle variations like 4-6 vs 4.6), and quota group definitions to ensure it shares the same rate limits as other Claude models.
Suggested Labels: enhancement, antigravity.
Proposed Next Steps:

1. Update src/rotator_library/providers/antigravity_provider.py:
   • Add claude-opus-4.6 to AVAILABLE_MODELS.
   • Add mappings in MODEL_ALIAS_MAP for claude-opus-4-6 -> claude-opus-4.6.
   • Include claude-opus-4.6 and its internal -thinking variant in the claude quota group in model_quota_groups.
   • Update the logic in _prepare_request (around line 3399) to automatically map claude-opus-4.6 to claude-opus-4-6-thinking.
2. Update src/rotator_library/providers/utilities/antigravity_quota_tracker.py:
   • Add claude-opus-4.6 to DEFAULT_MAX_REQUESTS for both standard-tier and free-tier.
   • Add mappings in _USER_TO_API_MODEL_MAP and _API_TO_USER_MODEL_MAP.
3. Update documentation and .env.example to reflect the new model's availability.

Missing Information (if any): None. The internal model name for Opus 4.6 is highly likely to be claude-opus-4-6-thinking given the pattern of Opus 4.5.

Something I want to correct:

Google Antigravity had (an hour ago) added Claude Opus 4.6 in the IDE.

For Pro subscribers. Ultra accounts have already had the model since 3 days ago.

It's been added to the dev branch ever since it came out on antigravity, use the dev branch
