xAI’s Grok 4.6 is now available in Amazon Bedrock
xAI's Grok 4.6, a frontier agentic model, is now available in Amazon Bedrock.
“Grok 4.6 widens that surface area considerably: it is available on both the bedrock-mantle and bedrock-runtime endpoints, and it supports the Converse API alongside Chat Completions and Responses.”
xAI's Grok 4.6 launched on Amazon Bedrock with a 500K token context window, configurable reasoning effort, and broad endpoint/API support, targeting long-running agents, coding, and knowledge work. As xAI's second Bedrock model, it deepens the partnership and expands enterprise access to frontier models on AWS, intensifying competition among cloud-hosted agentic AI offerings.
