Amazon adds Elon Musk's Grok 4.3 AI model to Bedrock, boosting enterprise AI options on AWS.

Amazon Web Services (AWS) has integrated Grok 4.3, the advanced AI model from Elon Musk's xAI, into its Bedrock platform. This model supports a large 1-million-token context window, ideal for processing extensive documents like financial reports and legal contracts, and claims the lowest hallucination rate among similar models. Running on Bedrock's Mantle inference engine, Grok 4.3 offers configurable reasoning levels and real-time streaming, priced per million tokens processed. This addition intensifies the competition among AI providers on AWS, which already hosts models from Anthropic and OpenAI, giving enterprises more powerful AI tools without infrastructure management.
