About

Gemma 2 27B IT is Google's 27B-parameter instruction model (June 2024): strong 27B-class quality on reasoning, math, and chat, with one of the largest fine-tune and quantization ecosystems of any open model. Weights are gated (manual approval) under the Gemma Terms of Use — custom, non-OSI (redistribution and use terms): "open weights", never "open source". 20.5k HF downloads. Superseded by Gemma 3 (which added vision and longer context), but the 27B remains a popular single-GPU-class deployment with unmatched community artifacts.
