Kind: release · Impact: medium

## In brief

- Google released Gemini 4 Hydrogen, available globally in Search for all users with improved intent understanding and broader link discovery
- The model handles multi-part questions, typos and highly specific requests better, breaking questions down and addressing each part
- Artificial Analysis places Gemini 4 Hydrogen's Intelligence Index just below Claude Sonnet 5.5 and GPT-6.1 Sol, at about a third of Sonnet's cost but roughly 2.5x that of Sol

## Why it matters

Developers building on Google Search, AI Studio or the Gemini API get a new default model with claimed better handling of complex queries, and the coding agent orchestration approach may change how multi-model coding tools are built.

## Versions

- Gemini 4 Hydrogen
- Gemini 4 Carbon
- Claude Sonnet 5.5
- GPT-6.1 Sol

## Timeline

- 2026-11-12: Google launched Gemini 4 Hydrogen, with Search availability and a coding agent model-switching system
