The Gemma 4 family of open-weight models from Google DeepMind on Amazon Bedrock in AWS GovCloud (US-West). With Gemma 4, you can build generative AI applications across reasoning, multimodal understanding, agentic, and software engineering workflows.

The Gemma 4 family on Amazon Bedrock includes three variants – Gemma 4 31B, Gemma 4 26B-A4B, and Gemma 4 E2B – spanning dense and mixture-of-experts (MoE) architectures with built-in reasoning, native function calling, support for 35+ languages and multimodal input across text, image, video and audio. Gemma 4 31B is suited for reasoning- and coding-heavy workloads with a 256K-token context window, Gemma 4 26B-A4B targets cost- and latency-sensitive workloads, and Gemma 4 E2B is the smallest variant, designed for low-latency interactive use cases. Gemma 4 runs on a new innovation in Amazon Bedrock designed for price performance, with improved support for tool calling, structured output, reasoning, and response streaming, so customers can build reliable generative AI applications with open-source models.
