Introducing Grok on Amazon Bedrock
AWS, Thursday, July 16th, 2026
xAI's Grok 4.3 arrives on Amazon Bedrock with configurable reasoning effort, tool calling, structured output, and image input.
AWS made Grok 4.3 from xAI available on Amazon Bedrock, adding another frontier model family to its managed inference platform.
The launch post covers what makes Grok 4.3 suited to agentic and enterprise workloads and walks through the capabilities teams typically reach for first.
These include basic chat requests, configurable reasoning effort to trade latency against depth, tool calling, structured output, image input, and stateful multi-turn conversations.
Access runs through the standard Bedrock APIs, so existing Bedrock applications can adopt the model without changing integration patterns.
