How it works
The homepage includes a chat playground that uses OpenRouter-backed Gemma instruction models and is rate-limited for anonymous access. Users can test model behavior before committing to local setup or deployment. The site also provides structured guides for downloading Gemma 4 from official sources such as Google docs, Kaggle, Hugging Face, and Ollama, and for running it locally with runtimes like llama.cpp, MLX, LM Studio, and vLLM.
Key capabilities
The site covers four Gemma 4 model variants: Gemma 4 E2B for edge devices, E4B for balanced local use, 26B A4B with sparse routing for efficient high-end performance, and 31B as the dense flagship. Guidance emphasizes starting with the smallest model that fits the job and moving up only when needed. Deployment options include Google Cloud for shared serving and autoscaling, as well as local and mobile workflows.

Pricing and limits
