Since its first launch, Gemma fashions have been downloaded over 100 million occasions, with the group creating over 60,000 variations for all types of use circumstances. We’re excited to introduce Gemma 3, our most succesful and superior model of the Gemma open-model household, constructing upon the success of earlier Gemma releases. We listened to group suggestions and added probably the most requested options, reminiscent of longer context, multimodality, and extra!
What’s new in Gemma?
Gemma 3 introduces multimodality, supporting vision-language enter and textual content outputs. It handles context home windows as much as 128k tokens, understands over 140 languages, and affords improved math, reasoning, and chat capabilities, together with structured outputs and performance calling. Gemma 3 is on the market in 4 sizes (1B, 4B, 12B, and 27B) as each pre-trained fashions, which may be fine-tuned to your personal use circumstances and domains, and general-purpose instruction-tuned variations.
How was Gemma constructed?
Gemma’s pre-training and post-training processes have been optimized utilizing a mixture of distillation, reinforcement studying, and mannequin merging. This strategy leads to enhanced efficiency in math, coding, and instruction following. Gemma 3 makes use of a brand new tokenizer for higher multilingual help for over 140+ languages and was educated on 2T tokens for 1B, 4T for 4B, 12T for 12B, and 14T tokens for 27B, on Google TPUs utilizing the JAX Framework.
For post-training, Gemma 3 makes use of 4 parts:
- Distillation from a bigger instruct mannequin into the Gemma 3 pre-trained checkpoints.
- Reinforcement Studying from Human Suggestions (RLHF) to align mannequin predictions with human preferences.
- Reinforcement Studying from Machine Suggestions (RLMF) to boost mathematical reasoning.
- Reinforcement Studying from Execution Suggestions (RLEF) to enhance coding capabilities.
These updates considerably improved the mannequin math, coding, and instruction following capabilities, making it the highest open compact mannequin in LMArena, with a rating of 1338.
The instruct variations of Gemma 3 use the identical dialog format as Gemma 2, so that you don’t must replace your tooling to replace to the most recent model for text-only enter. For picture enter, Gemma 3 permits specifying pictures interleaved with textual content.

Multimodality
Gemma 3 has an built-in imaginative and prescient encoder primarily based on SigLIP. The Gemma 3 imaginative and prescient mannequin, which was saved frozen throughout coaching, is similar throughout its completely different sizes (4B, 12B and 27B). Because of this, Gemma can use pictures and movies as inputs, permitting it to research pictures, reply questions on a picture, examine pictures, establish objects, and even reply about textual content inside a picture. Though the mannequin was initially created to work with pictures of 896×896 pixels, a brand new adaptive window algorithm is used to section enter pictures, permitting Gemma 3 to work with excessive decision and non-square pictures.
Enter: I must get heat. What button turns up the warmth?
Primarily based on the picture, the button that probably turns up the warmth is 暖房 (Danbou).
“暖房” means “heating” in Japanese. It is the button you’d press to activate the heating perform on the air conditioner/local weather management system.
The button with the plus signal (+) may alter the temperature after you have chosen the heating mode.
ShieldGemma 2
ShieldGemma 2 is a 4B picture security classifier constructed on Gemma 3. It outputs labels throughout key security classes, enabling security moderation of artificial pictures (from picture technology fashions) and pure pictures (which may very well be the enter filter of a Imaginative and prescient-Language Mannequin reminiscent of Gemma 3). Be taught extra about ShieldGemma 2.
What are you constructing?
We’re regularly astounded by the ingenuity of the Gemma group and the explosive progress of the Gemmaverse. From analysis labs pioneering novel fine-tuning methods – such because the SimPO method developed by Princeton NLP, which immediately optimizes for human preferences and not using a reference mannequin; INSAIT coaching state-of-the-art LLMs for Bulgarian – to builders coaching Gemma on solely new modalities like Nexa AI did with OmniAudio. We will not wait to see what breakthroughs you obtain subsequent.
