About this tag
AWS Bedrock is Amazon Web Services' managed service for building generative AI applications using foundation models. Recent discussions on WindowsForum.com cover OpenAI models like GPT-5.5 and Codex entering Bedrock for enterprise use, as well as the addition of xAI's Grok 4.3 with the Mantle inference path. A major theme is the end of Microsoft's exclusive OpenAI cloud arrangement, allowing OpenAI to offer products through AWS and other clouds. This shift turns Bedrock into a key platform in the multi-cloud AI landscape, where enterprise customers can access frontier models alongside AWS's identity, security, and compliance tools. For Windows and .NET teams, Bedrock represents a new infrastructure option for AI workloads.
