OpenAI Models Now Available on AWS Bedrock... Official Launch of GPT-5.5, Codex, and More

Model Usage Fees Integrated into Existing AWS Commitments

OpenAI's latest large language models (LLMs) are now available on Amazon Web Services (AWS)' integrated artificial intelligence (AI) model platform, Amazon Bedrock.

On June 2, OpenAI announced that it is officially launching its latest models, GPT-5.5 and GPT-5.4, as well as the coding agent Codex, on AWS's Amazon Bedrock.

With this launch, domestic companies utilizing AWS will also be able to easily access OpenAI's latest models. Usage of these models will be integrated into existing AWS Cloud commitments, allowing customers to avoid additional costs of separately adopting OpenAI models.

As a result, AWS now offers most of the major AI models on Amazon Bedrock, with the exception of Google Gemini. Previously, OpenAI agreed to remove the cloud exclusivity clause from its existing contract with Microsoft (MS). This clause had stipulated that OpenAI models could only be used through Microsoft's cloud service, Azure.

OpenAI's latest model, GPT-5.5, demonstrates outstanding performance in autonomous work handling, including code generation and debugging on large-scale codebases, data analysis, and document creation. In particular, it is noted for its strengths in agent-based coding and knowledge work domains. GPT-5.4 is a model that offers both high performance and cost efficiency, enabling inference in high-volume environments where cost effectiveness is critical. Both models support multiple languages, including Korean.

The coding agent Codex is a service used by over five million people each week, automating code generation, debugging, testing, and verification processes. Even when major elements of code are changed, it applies updates while recognizing inter-system connections. Codex on Amazon Bedrock can be used in major integrated development environments (IDEs), including the Codex app and Visual Studio Code (VSCode).

Kim Kyunghoon, CEO of OpenAI Korea, stated, "This collaboration is significant in that it allows Korean companies to more easily utilize OpenAI's latest models within the AWS environment they already trust." He emphasized, "Through Amazon Bedrock, enterprises can leverage OpenAI models in a secure, governed, and scalable AWS environment."

Ham Kiho, CEO of AWS Korea, explained, "This collaboration between AWS and OpenAI is an important step that enables corporate customers to simultaneously utilize best-in-class AI models and a trusted cloud infrastructure," adding, "Korean customers can now immediately adopt OpenAI's latest frontier models within their existing AWS environments through Amazon Bedrock."
