Amazon Bedrock now offers SpaceXAI's Grok 4.7, which supports configurable reasoning effort levels (low, medium, high, xhigh) and tool calling. In tests on three long-horizon agent tasks, the model answered 67 of 72 runs correctly, with xhigh achieving 18/18 and low achieving 15/18 while using roughly one-eighth the output tokens. The model has a 500K token context window and accepts text and image input with text output.

## Evidence

Verbatim from https://aws.amazon.com/blogs/machine-learning/build-long-horizon-agents-with-grok-4-7-on-amazon-bedrock/:

> The agent answered 67 of the 72 runs correctly. At xhigh it answered all 18 correctly, and at low it answered 15 of 18 while using about an eighth of the output tokens.
