Gemini 4 Hydrogen

Google has released Gemini 4 Hydrogen, a new AI model designed for speed and efficiency in everyday coding and agentic workflows, adapted from its more powerful Gemini 4 Carbon model. The model supports multimodal inputs (text, images, audio, and video) with a 1M token context window and is distributed across multiple Google platforms including the Gemini app, API, Google Sheets, and Google Search. Hydrogen prioritizes rapid execution for diverse tasks, positioning itself as a complement to Google's frontier models that focus on complex reasoning.
