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.
