Grok 4.6 becomes generally available on Amazon Bedrock

xAI's Grok 4.6 reached general availability on Amazon Bedrock on August 19, one week after its initial launch, with AWS adding cross-region inference support across every commercial Bedrock region. The frontier coding and agentic model offers a 500,000-token context window and four configurable reasoning-effort settings, moving Grok from a single endpoint into AWS's standard enterprise routing.
