xAI ships Grok 4.7 on its API with a 500K context window

What changed

xAI's Grok 4.7 remains available through its own API, and AWS added it to Amazon Bedrock in AWS GovCloud (US) on 19 October. The xAI route offers a 500K-token context and US regional endpoint; the new Bedrock route gives US public-sector teams supported GovCloud console and API access.

Why it matters

GovCloud distribution changes the procurement, residency and control path for regulated US workloads without independently changing the model's underlying capability evidence.

What to do

Confirm the exact GovCloud Regions, inference profile, retention, endpoint, price and approved model policy; then replay a representative coding or agent workload against the current xAI route before changing providers.

Caveat

AWS repeats capability claims rather than publishing independent results. Region, feature and pricing support can differ from xAI's direct API, and a new distribution route does not establish parity in context, tools, latency or safeguards.
