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.
xAI released Grok 4.6 for coding, agentic tasks, knowledge work, and image input. The API exposes a 500,000-token context window, four reasoning levels, and per-million-token prices of $2 input and $6 output below 200,000 prompt tokens, doubling above that threshold.
Why it matters: The release pairs a frontier agent model with unusually explicit context limits and a material long-context price step.
xAI released Grok 4 with native tool use and access to real-time search, and made it available through Grok subscriptions and its API.
Why it matters: The release made live retrieval and tools part of the base model proposition rather than an application-layer add-on, increasing pressure on other frontier providers to compete on connected work, not chat alone.
