AWS adds SpaceXAI's Grok 4.7 AI model to Amazon Bedrock, with agent tests

Grok 4.7 is on Amazon Bedrock, and AWS tested how its reasoning effort setting affects accuracy and token use in AI agents.

Announced by AWSPublished Checked

Summary

AWS says SpaceXAI's Grok 4.7 model is now available on Amazon Bedrock. AWS built a tool-calling agent and ran 72 test runs across four reasoning effort levels. Higher effort was more accurate but used far more output tokens, while low effort used about an eighth of the tokens of xhigh.

What changed

  • Grok 4.7 is now available on Amazon Bedrock through two cross-Region inference profiles.
  • It supports configurable reasoning effort, tool calling and structured output on Bedrock.
  • The agent answered 67 of 72 test runs correctly; xhigh got all 18 right.
  • Low effort answered 15 of 18 correctly with about an eighth of the output tokens.

“SpaceXAI’s Grok 4.7 is now available on Amazon Bedrock, which offers a choice of foundation models (FMs) from multiple providers.”

Founder takeaway

If you build agents on Bedrock, test Grok 4.7 on your own tasks at several effort levels with repeated runs. Consider low effort for simple or reviewed steps and higher effort for steps that weigh several candidate answers.
