Very fast token speed
Recommended for very fast responses at low cost for agentic subtasks, autocomplete and quick iteration. Critics say it trails frontier models on accuracy and reliability.
Very fast token generation
Diffusion-based open model people recommend for very fast token output, especially on a single GPU. Common caveat: output quality often trails regular autoregressive Gemma models.
