Grok 4.6 brings 500K context to GovCloud

SpaceXAI’s Grok 4.6 is now available on Amazon Bedrock in AWS GovCloud, with a 500,000-token context window and configurable reasoning effort. AWS says requests can route across both GovCloud regions and use the Responses, Chat Completions, or Converse APIs, giving public-sector builders another long-context agent surface inside the regulated cloud boundary; compare it with frontier-model price-performance before assuming availability alone changes the model choice.
