Amazon announces first-ever availability of OpenAI models for its cloud customers, company says, ‘The addition of…’

Amazon Web Services (AWS) has announced that OpenAI’s open weight models will be available for the first time on Amazon Bedrock and Amazon SageMaker AI. This will allow the company’s customers to build generative artificial intelligence (AI) apps, as this move will make OpenAI’s technology accessible to millions of AWS customers. In a blog post, Amazon has confirmed that OpenAI’s two new open-weight foundation models, gpt-oss-120b and gpt-oss-20b, will be offered on its platforms. According to AWS, when running in Amazon Bedrock, the larger model is three times more price-efficient than the comparable Gemini model, five times more than DeepSeek-R1, and twice as efficient as the OpenAI o4 model. This announcement reinforces AWS’s commitment to providing a wide selection of models. It expands the existing range of fully managed models in Amazon Bedrock and makes them accessible in Amazon SageMaker JumpStart. The announcement came after OpenAI launched two new openweight models, gpt-oss-120b and gpt-oss-20b that promises to deliver strong real-world performance at low cost.
