Customers can access advanced open weight models in Amazon Bedrock and Amazon SageMaker AI, bringing together OpenAI and the world’s most comprehensive and broadly adopted cloud.
AWS offers open weight models from OpenAI, making their models available to the millions of customers on AWS for the first time.
Customers can leverage the new open weight models’ advancing reasoning capabilities for agentic workflows, coding, scientific analysis, and mathematical problem-solving.
This news expands the selection of models on AWS, empowering customers with open weight models, which will help shape the future of GenAI technology.
Amazon Bedrock AgentCore leads the announcements, alongside new listings in AWS Marketplace and a $100 million investment to boost agentic AI development.
"Open weight models are an important area of innovation in the future development of generative AI technology, which is why we have invested in making AWS the best place to run them—including those launching today from OpenAI," said Atul Deo, director of product, AWS. "The addition of OpenAI as our newest open weight model provider marks a natural progression in our commitment to bringing cutting-edge AI to organizations worldwide, and the unmatched size of our customer base marks a transformative shift in access to OpenAI’s advanced technology."
"Our open weight models help developers—from solo builders to large enterprise teams—unlock new possibilities across industries and use cases," said Dmitry Pimenov, product lead, OpenAI. "Together with AWS, we’re providing powerful, flexible tools that make it easier than ever for customers to build, innovate, and scale."
The Pennsylvania Energy and Innovation Summit brought together Amazon leadership, policymakers, and energy and AI executives to advance U.S. technological leadership.
As organizations increasingly embrace agentic AI, they need a variety of models capable of executing complex tasks. OpenAI’s open weight models meet this need with a compelling performance-to-size ratio and advanced reasoning, including adjustable reasoning levels and chain-of-thought outputs that break down complex problems into logical steps. This makes them great for use cases like agentic workflows, coding, scientific analysis, and mathematical problem-solving.
These models support instruction-following and tool use—web search and code interpreter—to help them reference real-time information and perform multi-step tasks. Featuring a 128K context input window, these text-generation models enable customers to process longer documents and conversations, such as customer service transcripts, detailed technical documentation, academic papers, and more. Safety is a central component of the open weight models, and to support the responsible deployment of generative AI applications, each model has undergone comprehensive safety training and evaluation by OpenAI.
