Amazon Bedrock now offers Grok 4.7, a model from xAI designed for coding and knowledge work. This model features a 500K token context window and emphasizes endurance over raw speed. Independent benchmarks show Grok 4.7 outperforming Grok 4.6 in terms of intelligence, coding agent ability, and GDP value. However, a lower price doesn't guarantee lower costs, as output tokens per task have roughly doubled.
Bedrock supports various request types, including Responses, Chat Completions, InvokeModel, and Converse, all of which support this new model. The default reasoning effort level is set to high, so it's essential to consider this when building agents. Bedrock also offers cost-saving features like implicit prompt caching, guardrails, structured outputs, and service tier options.
