Summary
Microsoft added Anthropic’s Claude Fable 5 to Foundry on June 9, making the model available in Foundry Models and Foundry Agent Service while extending its role in GitHub Copilot.
Fable 5 is built for long-running, multi-stage work such as code refactoring, research synthesis and document-heavy analysis, with stronger vision capabilities for PDFs, charts, diagrams and dense tables.
Microsoft is pitching Foundry as the enterprise layer around the model, combining governance, observability, security controls and Microsoft IQ connections to organizational data across Microsoft 365, apps and the web.
Anthropic says the broadly available version includes added limits in cybersecurity, biology and chemistry, while a restricted Mythos 5 variant without those domain caps is reserved for select defensive-use participants.
Pricing in Foundry is set at $10 per 1 million input tokens and $50 per 1 million output tokens, underscoring Microsoft’s push to move customers from AI pilots into governed production use.
