Gemma 4 model weights in GGUF format, used by Understand's AI features and served locally by ullama (llama.cpp).

  • gemma-4-E4B-it-Q4_K_M.gguf โ€” the quantization qualified in SciTools' two-workload evaluation (chat quality 148.6 on the frozen GitAhead scale, 3/3 qualifying runs). Ship and use exactly this file: verdicts do not carry across quantizations.

Gemma is provided under and subject to the Gemma Terms of Use found at ai.google.dev/gemma/terms. By downloading these weights you agree to those terms, including the Gemma Prohibited Use Policy (ai.google.dev/gemma/prohibited_use_policy). This repository redistributes the weights unmodified apart from quantization; it is not endorsed by Google.
