Most AI handles one task well. The harder problem is the complex workflow that spans hours. Effective enterprise AI must be capable of managing complex workflows that require planning, adaptation, and persistence over extended periods.
We’re excited to announce that Claude Opus 5, Anthropic’s most advanced Opus model and the first Opus model in the fifth generation of Claude, is now available in Microsoft Foundry. Whether you are building agents, coding software, or automating enterprise workflows, Opus 5 is designed to work for hours, find paths around obstacles, navigate codebases like a senior engineer, and support deeper reasoning and higher accuracy. Combined with Microsoft Foundry’s enterprise platform including Foundry evaluation tools, native security controls, governance, and scalable deployment, organizations can confidently build and operate the next generation of AI applications.
Writing a good function isn’t the hard part anymore. The hard part is understanding how a change ripples through a large repository, across files, across architecture decisions someone made years ago. Claude Opus 5 is Anthropic’s strongest Opus model yet for that kind of work: it navigates large codebases with the judgment of an engineer, adjusts its approach as a project evolves, and can run for hours, even overnight, on a senior engineering task, working around obstacles instead of stalling on them.
Builds long-running agents that can work for hours
Many enterprise workflows cannot be completed in a single interaction. Research, software engineering, document review, and operational automation often require AI systems that can work continuously over multiple steps while responding intelligently to changing conditions.
Claude Opus 5 powers dependable long-running agents, recovering from errors, and reaching their objectives. Opus 5 plans a workflow, adapts the plan when something breaks, and holds context across tools and subagents to see it through. Combined with Microsoft Foundry Agent Service, developers can build reliable agents that automate sophisticated business processes while maintaining enterprise governance and observability.
Transforms enterprise knowledge work
From precise financial workflows to professional work that runs for days, , Opus 5 is built to handle the density of that work with deeper reasoning for long documents, higher accuracy for complex analysis, and raises the bar for the practical tasks that fill a workday. It is built for enterprise work, powering agents that run multi-day projects end-to-end, and follows instructions precisely, stays in scope, and produces professional-grade spreadsheets, slides, and docs.
Brings deeper reasoning to financial workflows
Financial analysis cannot tolerate shortcuts. Opus 5 is built to read a dense filing, hold a chart or table in context alongside it, and carry that thread across an entire transaction or reporting cycle, not just the page in front of it. That’s the reasoning investment research, corporate finance, risk analysis, and due diligence work depend on.
Understands documents, charts, and visual information
Enterprise work is increasingly visual, not just text. Critical information lives in scanned PDFs, dashboards, invoices, technical diagrams, and screenshots of systems that may never have been formally documented. Claude Opus 5 brings advanced vision capabilities to the Opus class, enabling AI to accurately understand and reason over visual content rather than simply extract text from it. Combined with Foundry IQ, which connects agents to documentation and process knowledge already embedded across your organization, AI agents can securely access, interpret, and act on enterprise data in context. Together, these capabilities provide the foundation for intelligent document processing, enterprise search, and a new generation of multimodal applications.
Automates work across multiple applications
Claude Opus 5 is also a strong model for computer use. By combining high-resolution vision with deep reasoning, the model can interact with software interfaces and complete workflows that span multiple applications. It can navigate interfaces and execute multi-step tasks requiring planning and judgment. This opens new opportunities for automating repetitive business operations while reducing manual effort.
Enterprise-ready AI with Microsoft Foundry
Claude Opus 5 is Zero Data Retention compatible. Powerful models alone are not enough for production AI. Organizations also need platform capabilities to build, evaluate, secure, and scale enterprise applications.
With Opus 5 in Microsoft Foundry, developers can:
- Build AI applications using Azure-native authentication, networking, billing, and governance.
- Evaluate model quality and compare prompts, models, and workflows before deployment.
- Ground AI applications with enterprise data and knowledge using Microsoft IQ.
- Monitor performance and improve agents through continuous evaluation.
- Deploy production AI with the security, compliance, and operational controls enterprises expect.
Microsoft Foundry gives organizations the complete platform needed to move from experimentation to production with confidence.
