AWS announced that xAI’s Grok 4.6 is available in the Amazon Bedrock model catalog for long-running agents, coding, and knowledge work. The model offers a 500K-token context window and low, medium, high, and xhigh reasoning effort, and can be accessed through bedrock-mantle or bedrock-runtime; the latter adds the Converse API, streaming, and cross-Region inference. AWS says Grok 4.6 launched on Bedrock on August 18, 2026; capability, benchmark, and pricing details should be checked against the current AWS and xAI documentation.
