About this model
Gemini 4 Hydrogen is Google's reasoning model for coding, tool use, and sustained agent tasks. It accepts text, images, audio, video, and documents and generates text.

Standard foreground generation supports up to 65,536 thinking and output tokens per segment; longer generation requires Google's continuation or long-decode features. It supports low, medium, high (default), and xhigh thinking levels, function calling, structured output, streaming, and implicit context caching.
