About

Gemma-3-4B-IT is Google's small multimodal model (February 2025): 4.3B parameters handling text and images, 128K-token context, 140+ languages — with 1.2M Hugging Face downloads. It brought vision to the 4B class with genuinely strong quality-per-parameter. Weights are gated (manual approval) under the Gemma Terms of Use — custom, non-OSI: "open weights", never "open source". The go-to for on-device multimodal (phones, laptops); 4B capacity limits deep reasoning.
