These models constitute the vast majority of the Azure AI Foundry Models and are provided by trusted third-party organizations, partners, research labs, and community contributors. These models offer specialized and diverse AI capabilities, covering a wide array of scenarios, industries, and innovations. An example of models from Partners and community are the family of large language models developed by Anthropic.

Anthropic includes Claude family of state-of-the-art large language models that support text and image input, text output, multilingual capabilities, and vision. See Anthropic's privacy policy to know more about privacy. Learn how to deploy Anthropic models .

Characteristics of Models from Partners and Community:

• Developed and supported by external partners and community contributors.
• Diverse range of specialized models catering to niche or broad use cases.
• Typically validated by providers themselves, with integration guidelines provided by Azure.
• Community-driven innovation and rapid availability of cutting-edge models.
• Standard Azure AI integration, with support and maintenance managed by the respective providers.

Models from Partners and Community are deployable as Managed Compute or serverless API deployment options. The model provider selects how the models are deployable.

About this model

Claude Opus 5 is Anthropic's most advanced Opus model, powering long-running agents while delivering improvements in coding and professional work. It brings near-Fable intelligence to the model teams rely on daily for long-horizon coding and complex agentic orchestration.

Version 2

Version 2 of Claude Opus 5 is hosted on Azure infrastructure. Microsoft Foundry Claude models on Azure infrastructure have full Azure data residency for inference processing. Version 2 supports both Global Standard and US DataZone deployment types.

Version 2 currently supports core Messages API features including tool calls and prompt caching. If you need additional features including structured outputs, Web Search, and Files, you can use Version 1 which is hosted on Anthropic infrastructure. We will be adding those API capabilities to Version 2 in the coming months. See API feature differences .
