OpenAI

OpenAI made GPT-5.4, GPT-5.5, and Codex generally available through Amazon Bedrock. AWS shops can now use OpenAI models inside existing IAM, compliance, and procurement workflows instead of adopting a separate vendor stack.

OpenAI launched Guaranteed Capacity, offering long-term reserved access to model compute in exchange for one- to three-year commitments and discounted tokens. It matters because enterprises can now buy explicit supply guarantees instead of relying on shared capacity during a compute-constrained period.

AWS and OpenAI moved their expanded partnership into limited preview, bringing OpenAI models, Codex, and Bedrock Managed Agents onto AWS. That gives teams a direct AWS path for OpenAI-backed agent workflows instead of waiting on the earlier coming-soon timeline.
