Multi-model coding loop: Gemini Flash + Claude via Antigravity

A recent demo shows using Antigravity to route coding tasks between a fast model (Gemini 3 Flash) for scaffolding and a stronger model (Claude Opus 4.5) for review and fixes. The workflow iterates on repo files with model switching to balance speed, quality, and cost, with claims of leveraging free tiers; availability and limits may vary by provider.
