Google released four Gemma 4 variants (2B, 4B, 26B MoE, 31B Dense) under the OSI-approved Apache 2.0 license with native video, image, and audio processing plus 256K context windows. The 31B dense model scores 84.3% on GPQA Diamond versus Gemma 3's 42.4%, and adds native function-calling, structured JSON output, and system instructions for building autonomous agents. Trained on 140+ languages with commercial use permitted, this is the strongest open-weight model family available for local deployment — the Apache 2.0 license removes the last friction for enterprise adoption.
