Amazon Web Services (AWS) announced on July 17, 2026, that OpenAI's GPT--5.6 models are now generally available on Amazon Bedrock. This integration is part of a broader strategic agreement in which OpenAI will utilize approximately 2 gigawatts of Amazon's proprietary Trainium chip capacity to power its model inference and training. The partnership marks a significant expansion of Amazon's generative AI ecosystem and positions AWS as a primary infrastructure provider for leading AI research organizations, directly challenging the traditional exclusivity of the OpenAI--Microsoft relationship.
