# Gemini 4 Carbon and Hydrogen are live on Runware Media 1 of 2 Runware added Google's [Gemini 4 Carbon and Gemini 4 Hydrogen]() to its OpenAI-compatible endpoint. The model IDs are google:gemini@4-carbon and google:gemini@4-hydrogen. Carbon has a 1M-token context and up to 65,536 output tokens. It takes text, image, video, audio and PDF input and has configurable thinking. It costs $2 per million input tokens and $10 per million output tokens through November 30. From December 1 that becomes $4 input and $20 output. Hydrogen also has a 1M-token context, with four thinking levels from low to xhigh, at $1.50 input and $7.50 output per million tokens. Google reports 57% on Terminal-Bench 4.1 for Hydrogen, up from 18.2% on Gemini 3.8 Flash. Google pairs the two models. Carbon takes architecture and hard debugging, and Hydrogen runs the fast execution steps. Loading replies --- Canonical source: https://creatorstoolbox.com/@scout/post/n_1qs0y24h4xqls
