Amazon Net Companies (AWS) introduced on August 5 that OpenAI’s new open weight basis fashions—gpt-oss-120b and gpt-oss-20b—at the moment are obtainable on Amazon Bedrock and Amazon SageMaker AI, marking a major growth in generative AI choices on its cloud platform.
Key Highlights
First-time integration with AWS
That is the primary time OpenAI’s open weight models are being made accessible by way of AWS, providing clients a streamlined path to construct and deploy generative AI applications utilizing acquainted AWS instruments and infrastructure.
Efficiency & value effectivity
The bigger mannequin, gpt-oss-120b, delivers 3x higher price-performance than Google’s Gemini, 5x higher than DeepSeek-R1, and 2x higher than OpenAI’s personal o4 mannequin, in line with Aamazon.
Assist for AI brokers and sophisticated reasoning
With superior reasoning capabilities, these fashions are well-suited for agentic workflows, coding, scientific evaluation, and multi-step problem-solving. They assist options like chain-of-thought outputs, internet search, and code interpretation, together with a 128K token context window for processing giant paperwork.
Safety and security measures
OpenAI’s fashions are built-in with Amazon Bedrock’s Guardrails, blocking as much as 88% of dangerous content material utilizing configurable filters. The fashions have additionally undergone complete security analysis to assist accountable deployment.
Broader entry by way of SageMaker
On Amazon SageMaker AI, clients can use OpenAI’s fashions for pre-training, analysis, fine-tuning, and customized deployment, leveraging AWS’s sturdy suite of machine studying instruments.
Trade adoption
Amazon said that organisations equivalent to Pfizer, Siemens, the PGA TOUR, and GoDaddy already use Amazon Bedrock for GenAI-powered transformations. OpenAI now joins Meta, Mistral AI, and others as a part of AWS’s rising ecosystem of open weight mannequin suppliers, it mentioned.
“Open weight fashions are an vital space of innovation sooner or later improvement of generative AI know-how, which is why we now have invested in making AWS the most effective place to run them—together with these launching at the moment from OpenAI,” mentioned Atul Deo, director of product, AWS. “The addition of OpenAI as our latest open weight mannequin supplier marks a pure development in our dedication to bringing cutting-edge AI to organizations worldwide, and the unequalled measurement of our buyer base marks a transformative shift in entry to OpenAI’s superior know-how.”
“Our open weight fashions assist builders—from solo builders to giant enterprise groups—unlock new prospects throughout industries and use circumstances,” mentioned Dmitry Pimenov, product lead, OpenAI. “Along with AWS, we’re offering highly effective, versatile instruments that make it simpler than ever for patrons to construct, innovate, and scale.”
