AWS Unveils OpenAI gpt oss Models on Amazon Bedrock, Boosting Generative AI Innovation

Today, Amazon Web Services (AWS) revealed that OpenAI's open weight models, specifically gpt-oss-120b and gpt-oss-20b, are now available via Amazon Bedrock and Amazon SageMaker AI for the first time. This strategic move allows organizations to build generative AI applications swiftly and effectively on AWS, one of the most comprehensive cloud platforms globally. These models signify an expansion of OpenAI's offerings, making powerful AI technologies accessible to millions of customers on AWS. OpenAI's larger model boasts a cost-performance ratio significantly better than competing alternatives, reinforcing AWS's dedication to delivering model choice and driving innovation in generative AI.

The open weight models enhance reasoning capabilities, which are crucial for implementing AI agents in various business transformations. With Amazon Bedrock AgentCore, enterprises can deploy and operate highly effective agents using OpenAI models within the platform, ensuring the scale and security needed for production applications. Users can integrate these models with Amazon Bedrock’s security tools and features like Guardrails, which blocks a substantial percentage of harmful content through customizable safeguards. Amazon SageMaker AI further supports these efforts by offering comprehensive tools for pre-training, evaluation, fine-tuning, and model deployment.

Atul Deo, AWS's director of product, emphasized the significance of open weight models in the evolution of generative AI technologies. By integrating OpenAI's models, AWS is steadily advancing its capability to supply cutting-edge AI solutions to global organizations. OpenAI’s product lead, Dmitry Pimenov, underscored the value these models bring to developers across industries, facilitating new potentials with robust and adaptable tools.

OpenAI's models offer a superior performance-to-size ratio with an adaptable reasoning framework, enabling them to handle complex tasks efficiently. They apply chain-of-thought outputs, breaking down intricate problems step-by-step for applications such as agentic workflows, coding, scientific analysis, and mathematical problem-solving. With a 128K context input window, these text-generation models proficiently process extensive documents and dialogues, proving beneficial for tasks like customer service interactions and thorough technical documentation.

Safety remains pivotal in deploying OpenAI's models, which undergo extensive safety training and evaluations. This ensures responsible generative AI application deployment. Amazon Bedrock already aids a diverse array of global customers—from agile startups to multinational corporations and government entities—by offering the flexibility to securely develop and customize generative AI applications. Among the notable users leveraging Amazon Bedrock are companies like DoorDash, GoDaddy, Lonely Planet, LexisNexis Legal & Professional, Pfizer, and Siemens.

Meanwhile, OpenAI and NVIDIA have collaborated to optimize the open-weight models for NVIDIA GPUs, enhancing performance on both cloud systems and personal computing devices. Through tools and frameworks such as Ollama, llama.cpp, and Microsoft AI Foundry Local, users can achieve swift inference with the models, highlighting NVIDIA's leadership from training to inference and emphasizing AI's span from cloud solutions to personal devices. The models utilize the mixture-of-experts architecture, supporting long context lengths suitable for detailed reasoning tasks.

On a broader spectrum, OpenAI has introduced these open-weight models to Microsoft’s platforms, offering flexibility for enterprise and local deployment on Azure AI Foundry and Windows AI Foundry. Azure AI Foundry provides a comprehensive platform encompassing the entire AI application lifecycle, enabling users to run and adapt models seamlessly. This release reasserts OpenAI's drive towards open and adaptable AI solutions, enhancing control and flexibility for developers and enterprises.

These advancements represent OpenAI's shift towards open-weight models, contrasting its prior proprietary-focused approach, as it seeks to democratize access to its technologies. With aims firmly rooted in fostering innovation underpinned by democratic principles, OpenAI, supported by platforms like AWS and Azure, continues to lead a transformative journey in AI development, ensuring its benefits stretch globally. As the competitive landscape in AI tech evolves, OpenAI's latest offerings serve as pivotal tools for wide-reaching, beneficial applications powered by open weight AI models.
