xAI’s Grok 4.6 is now available on Amazon Bedrock, offering a frontier model optimized for long-running agents, coding, and complex knowledge work. The model features a 500K token context window and introduces four configurable reasoning effort levels, including a new 'xhigh' setting for deeper analysis. It is accessible via both the bedrock-mantle and bedrock-runtime endpoints, supporting APIs such as Converse, Chat Completions, and Responses. Key enhancements include cross-Region inference profiles for data residency compliance, Amazon Bedrock Guardrails for content safety, and invocation logging for auditing. Pricing varies by service tier, with options for Standard, Priority, and Flex access to balance cost and latency requirements. Developers can integrate the model using OpenAI-compatible SDKs or AWS boto3, utilizing features like prompt caching and encrypted reasoning content. This release expands xAI's presence on the platform beyond its previous Grok 4.3 launch.
