Google Releases Gemma 4 12B Open Weights, Reportedly Beating Last Year's Gemma 3 27B

LLM Stats·low signal

Google released Gemma 4 12B as open weights in early June, which open-weight trackers report scores 77.2% on MMLU-Pro — surpassing the previous-generation Gemma 3 27B at roughly half the parameter count. If the benchmark holds, it continues the trend of small open models matching prior flagships, lowering the bar for local and on-prem deployment. Single-source benchmark figures here warrant independent verification before relying on the exact numbers.
