Amazon and OpenAI Partner to Offer AI Models as AWS Service

OpenAI has partnered with Amazon Web Services (AWS) to make its two open-weight reasoning models available as a service on AWS. This marks the first time OpenAI models will be available to power AI services like Bedrock and SageMaker AI on AWS. The partnership comes as a competitive move for both companies, with AWS now in the same sentence as OpenAI, and Microsoft's Azure being OpenAI's most significant cloud partner to date.

OpenAI, the leading AI startup, has partnered with Amazon Web Services (AWS) to make its two open-weight reasoning models available as a service on AWS. This marks the first time OpenAI models will be available to power AI services like Bedrock and SageMaker AI on AWS. The partnership comes as a competitive move for both companies, with AWS now in the same sentence as OpenAI, and Microsoft's Azure being OpenAI's most significant cloud partner to date [1].

The partnership includes OpenAI's gpt-oss-120b and gpt-oss-20b models, which offer advanced reasoning capabilities suited for AI agents, coding, scientific analysis, and mathematical problem-solving. These models will be available via Amazon Bedrock and SageMaker AI, allowing customers to quickly build generative AI applications [2].

The move is significant for AWS, which has previously relied on competitors like Microsoft and Oracle for AI services. By offering OpenAI models, AWS aims to meet the growing demand for a variety of AI tools and stay competitive in the cloud market [1].

For OpenAI, the partnership provides an opportunity to strengthen its position, especially given the strained relationship with Microsoft. By offering its models on AWS, OpenAI can reach a broader audience and potentially undercut competitors like Meta, which has been hesitant to open source its upcoming "superintelligence" models [1].

The partnership also benefits AWS's enterprise customers, who can now easily experiment with OpenAI models for their hosted AI apps. This move aligns with AWS's strategy of offering a range of AI tools to businesses, making it a kind of "supermarket" for AI services [1].

The addition of OpenAI's open-weight models to AWS further emphasizes the company's commitment to model choice and innovation in generative AI technology. With these models, AWS aims to meet the diverse needs of its customers and maintain its momentum in the competitive cloud market [2].
