## Summary

Grok 4.7, xAI’s newest model, is now available on Amazon Bedrock. It offers a 500K token context window and four configurable reasoning effort levels—low, medium, high, and xhigh. The model runs on the bedrock‑runtime endpoint through cross‑Region inference profiles and supports the Responses, Chat Completions, and Converse APIs, accepting text and image input.

According to xAI, Grok 4.7 is its most capable model for coding and knowledge work. It works longer on difficult tasks, verifies its own output more carefully, and uses a larger base model trained with a longer reinforcement learning run. xAI reports gains across evaluations in software engineering, terminal work, electrical engineering, legal work, and clinical reasoning. The model also includes a new safeguard stack and is the strongest it has tested on refusals and jailbreak resistance, with limited risky dual‑use prompts for cyber security partners.

## Key points

- Grok 4.7 offers 500K token context window and four reasoning effort levels on Amazon Bedrock.
- xAI claims Grok 4.7 is its most capable model for coding and knowledge work, with improved self‑verification and longer task endurance.
- The model is served via Bedrock runtime with Responses, Chat Completions, and Converse APIs, and supports image input and tool calling.

## Why it matters

The release expands Bedrock’s long‑context capabilities, enabling developers to build more reliable coding and agentic applications. It also introduces new safety safeguards and cross‑region routing options that could influence how AI workloads are deployed and priced.
