## Why it matters

Most-viewed third-party reading of the Gemini agent launch (~398k views); it captures the rebranding of 'Gemini' as an agent that can run Claude.

## Summary

"Google just announced that Gemini is not a model / it's actually the agent harness, and they are going to add Claude models". This simplifies the launch: Gemini remains the name of Google's models (e.g. Gemini 4 Argon) and is now also the name of the agent product, which lets users pick Anthropic's Claude (Opus 5.5 per other posts).
