Abstract: We introduce Gemma 3, a multimodal addition to the Gemma family of
lightweight open models, ranging in scale from 1 to 27 billion parameters. This
version introduces vision understanding abilities, a wider coverage of
languages and longer context - at least 128K tokens. We also change the
architecture of the model to reduce the KV-cache memory that tends to explode
with long context. This is achieved by increasing the ratio of local to global
attention layers, and keeping the span on local attention short. The Gemma 3
models are trained with distillation and achieve superior performance to Gemma
2 for both pre-trained and instruction finetuned versions. In particular, our
novel post-training recipe significantly improves the math, chat,
instruction-following and multilingual abilities, making Gemma3-4B-IT
competitive with Gemma2-27B-IT and Gemma3-27B-IT comparable to Gemini-1.5-Pro
across benchmarks. We release all our models to the community.
