Claude Fable 5, Anthropic\u2019s latest Frontier model, is available today in Microsoft Foundry<\/a>, powering agents in GitHub Copilot<\/a> and Foundry Agent Service<\/a>. Claude Fable 5 makes Mythos-level capabilities available to all customers, with strong safeguards designed to make it safe for general use.<\/p>\n\n\n\n

Fable 5 is designed for long-running, multi-stage, and asynchronous tasks like complex code refactoring, deep research synthesis, and document-heavy workflows. This elevated level of autonomy changes what teams can ask AI to do. Enterprises can now delegate sophisticated multi-turn projects to agents, enabling them to reason over your organization’s data to solve real problems.<\/p>\n\n\n\n

For enterprises, this Frontier capability is only part of the equation. To turn autonomy into real business impact, organizations need a platform to evaluate, ground, govern, deploy, and scale<\/a> these systems in production.<\/p>\n\n\n\n

That is where Microsoft Foundry<\/a> comes in. Foundry brings Anthropic\u2019s next generation of intelligence into the broader Microsoft agent platform, helping enterprises build ambitious, high-impact AI solutions on Azure with the security, governance, reliability, and operational controls required for real business workflows.<\/p>\n\n\n\n

Combined with Microsoft IQ<\/a>, Fable 5 can reason over your team, your knowledge, and your data across Power BI, your applications, and the web, with a continuously updating view that learns as usage grows.<\/p>\n\n\n\n

The next generation of Frontier intelligence<\/h2>\n\n\n\n

According to Anthropic, Claude Fable 5<\/a> is the next generation of intelligence for the hardest knowledge work and coding problems. It can handle tasks previous models couldn\u2019t sustain and represents a step change in what teams can hand off to Claude.<\/p>\n\n\n\n

Claude Fable 5 can plan its approach, check progress against the goal, and refine its work as it goes, instead of waiting for the next instruction. This makes it well suited for complex coding tasks, research workflows, and long-running knowledge work where the model needs to reason across multiple steps.<\/p>\n\n\n\n

With improved vision capabilities, Claude Fable 5 is also a strong fit for multimodal projects involving documents, PDFs, diagrams, charts, and dense tables. It does not just read the words on a page; it can interpret the meaning carried by visual and structured information. When critical context is embedded in a chart, schematic, or complex table, Claude Fable 5 can take it in and reason over it, helping finance, legal, analytics, and architecture teams work through material that is often reviewed manually today.<\/p>\n\n\n\n

Claude Fable 5 real-world enterprise use cases<\/h2>\n\n\n\n

For business leaders, Claude Fable 5<\/a> changes how knowledge work is accomplished across the organization. Fable 5 is a Frontier general-purpose model designed to help support complex, cross-functional tasks that span reasoning, creation, and execution.<\/p>\n\n\n\n

Key enterprise use cases include:<\/strong><\/p>\n\n\n\n
