Grok 4.7 Launches on Amazon Bedrock with Real-World Tests of Each Reasoning Tier
Understand the story
According to the AWS Machine Learning Blog on October 13, 2026, Grok 4.7 is now available on Amazon Bedrock. The author built long-running agents with tool-calling capabilities on the model and evaluated its reasoning tiers with three brute-force-verified tasks that have unique correct answers. Results showed 67 out of 72 total runs answered correctly; the xhigh tier answered all 18 runs correctly, while the low tier answered 15 of 18, with low-tier output tokens about one-eighth of xhigh and median runtime of 18 seconds versus 106 seconds. The report indicates Grok 4.7 on Bedrock allows trade-offs between accuracy and time/cost across reasoning tiers, and performs reliably in tool-calling agent scenarios.
