Grok 4.7 is now available on Amazon Bedrock. The author built a tool-calling agent on it and benchmarked reasoning effort levels with three tasks brute-force verified to have a single correct answer: 67 of 72 runs answered correctly; the xhigh level got 18 of 18, while the low level got 15 of 18 with output tokens about one-eighth of xhigh, and median time 18 seconds versus 106 seconds.
Why it matters: The article gives correctness rates and token costs per reasoning level across 72 verifiable runs, plus transferable evaluation and monitoring methods.
xAI's Grok 4.7 is now available on Amazon Bedrock, offering a 500K token context window and four reasoning effort levels: low, medium, high, and xhigh.
Why it matters: The article covers how to access it on Bedrock, reasoning effort configuration, and cost trade-offs, so readers can directly plan their usage and spend.
