With a 128K context window under the Gemma Terms of Use, it provides strong coding and multimodal capability in a 12B parameter footprint — deployable on a single mid-range GPU. ## At a Glance **Where Gemma 3 12B leads** - 85.4% HumanEval — excellent function-level code completion for a 12B model - 60.6% MMLU-Pro — competitive academic knowledge at 12B scale - 128K context window - Multimodal: text and image inputs at 12B scale - Single-GPU deployable (in quantised form) - Open weights on Hugging Face **Where it lags** - 60.6% MMLU-Pro — below Phi-4 (70.4% at 14B) despite similar size - Below Gemma 3 27B on all benchmarks (expected) - Gemma Terms of Use — not fully permissive (not Apache 2.0 / MIT) - Text+vision only **Best for:** Resource-constrained open-weight multimodal deployments; edge and on-device inference; teams that need vision at 12B scale. ## What Gemma 3 12B Is Gemma 3 12B is the mid-tier model in Google's Gemma 3 family, released March 12, 2025 alongside the 1B, 4B, 12B, and 27B variants. At 12B parameters with multimodal capability and a 128K context window, it is designed for deployments where the 27B model's infrastructure requirements are too high. Its 85.4% HumanEval score is strong for a 12B model — approaching the 87.8% of the 27B version despite having less than half the parameters. This reflects Google's training efficiency improvements in the Gemma 3 generation. For pure text tasks requiring strong knowledge, Phi-4 (14B, 70.4% MMLU-Pro) outperforms Gemma 3 12B (60.6%) at a similar size and with a fully permissive Apache 2.0 license. Gemma 3 12B is preferred when multimodal vision capability is a requirement. ## Specifications | Field | Value | |---|---| | Organization | Google | | Parameters | 12B (dense) | | Context window | 128,000 tokens | | License | Gemma Terms of Use | | HuggingFace | [google/gemma-3-12b-it](https://huggingface.co/google/gemma-3-12b-it) | | Release date | March 12, 2025 | | Knowledge cutoff | September 2024 | | Modality | Text + Vision (multimodal) | ## Pricing Gemma 3 12B is available as open weights under the Gemma Terms of Use.
