Amazon Web Services (AWS) has broadened its AI offerings by adding Anthropic’s latest Claude 4 models on its Bedrock platform, alongside OpenAI’s new open-weight models available on both Bedrock and SageMaker.
Variety and Accessibility of Models on AWS
AWS customers now have access to a diverse range of large language models (LLMs), including proprietary Claude 4 and OpenAI’s open-weight models, all accessible via Bedrock, with OpenAI’s models also available in the SageMaker AI workshop.
Enabling Generative and Agentic AI Workflows
These integrations support advanced AI capabilities tailored for enterprises, facilitating generative content creation and agentic workflows directly on AWS’s cloud infrastructure.
Strategic Partnerships with Anthropic and OpenAI
Announced on August 5 and 6, AWS’s agreements with Anthropic and OpenAI position the cloud giant as a versatile AI platform, allowing businesses to mix and match LLMs to suit security and scalability needs.
Details on Claude 4 Models and OpenAI’s Open-Weight Offerings
Anthropic’s Claude 4 models (Opus 4.1 and Sonnet 4) are now available as managed services on Bedrock via API access, while OpenAI’s open-weight models (gpt-oss-120b and gpt-oss-20b) are offered on both Bedrock and SageMaker platforms.
AWS Competes with Microsoft and Google in AI Cloud Services
While Microsoft Azure holds exclusive rights to OpenAI’s closed models and Google Cloud promotes its Gemini family and Vertex AI, AWS emphasizes a broad and hybrid model portfolio, blending proprietary and open models from top AI providers.
Key Features of the New AI Models
Claude Opus 4.1 offers powerful agentic capabilities and detailed contextual understanding, whereas Claude Sonnet 4 provides a cost-effective balance of performance for everyday tasks. OpenAI’s models feature large context windows, tool usage, and real-time data referencing.
Benefits of Open vs. Closed AI Models
Closed models deliver optimized performance for specific applications and IP protection, while open models offer customization and deployment flexibility, often used for research and tailored solutions. SageMaker provides a sandbox environment for open model experimentation.
AWS Bedrock’s Expanding AI Ecosystem
Bedrock now hosts over 100 models from leading AI developers, including exclusive managed offerings, serving major clients like DoorDash, GoDaddy, Pfizer, Siemens, and more to drive innovation and digital transformation.
Industry Leaders Praise AWS AI Expansion
Anthropic’s Kate Jensen highlights the models’ ability to accelerate workflows and elevate AI from tool to collaborator, while AWS and OpenAI executives emphasize AWS’s role in democratizing access to advanced generative AI technologies.
