Today, AWS announces the availability of the Gemma 4 family of open-weight models from Google DeepMind on Amazon Bedrock. 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 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.
Gemma 4 models are available in the following AWS Regions: US East (N. Virginia), US East (Ohio), US West (Oregon), and Europe (Frankfurt). To get started, visit Gemma 4 model detail pages in our documentation.
