Amazon Bedrock in AWS GovCloud (US) now supports SpaceXAI Grok 4.6, a frontier model built for coding, agentic tasks, and knowledge work. Grok 4.6 is SpaceXAI’s latest flagship model, built for long-running agents and ambitious interactive and visual work. It offers 500k context window and configurable reasoning efforts (low, medium, high, xhigh).

The model runs on the bedrock-runtime endpoint with support for the Responses, Chat Completions, and Converse APIs, and customers can access Grok 4.6 at scale with cross-Region inference routing requests across both AWS GovCloud (US) Regions. Grok 4.6 is also avialable via the bedrock-mantle endpoint in AWS GovCloud (US-East).

To get started, review the [model card for Grok 4.6](https://docs.aws.amazon.com/bedrock/latest/userguide/model-card-xai-grok-4-6.html) in the Amazon Bedrock User Guide.
