Amazon Bedrock now supports SpaceXAI Grok 4.6 with Cross Region Inferencing

Posted on: Aug 19, 2026

Amazon Bedrock now supports SpaceXAI Grok 4.6, a frontier model built for coding, agentic tasks, and knowledge work, with US Geo and Global cross-Region inference. Customers can now access Grok 4.6 at scale with cross-Region inference routing requests across multiple AWS Regions for higher throughput and lower inference costs.

Cross-Region inference automatically routes inference requests across multiple AWS Regions to give you higher throughput, without you needing to manage capacity across multiple Regions. The US Geo inference profile—us.xai.grok-4.6—routes requests only within the US geography, so you can scale while keeping data processed within the United States to meet data residency requirements. The Global inference profile—global.xai.grok-4.6—serves requests from any commercial AWS Region where the model is available, giving you the broadest access to Bedrock capacity and the highest throughput during demand spikes, at a lower per-token cost. The model runs on the bedrock-runtime endpoint with support for the Responses, Chat Completions, and Converse APIs, and works with the same account-level controls you already use for other models on Bedrock, including model invocation logging (deliverable to Amazon S3 or Amazon CloudWatch Logs), Amazon CloudWatch metrics, and cost itemization in AWS Cost Explorer and the AWS Cost and Usage Report.

Cross-Region inference for Grok 4.6 is available in all AWS Regions where Amazon Bedrock is offered. To get started, review the model card for Grok 4.6  in the Amazon Bedrock User Guide.
