Copilot Studio Expands Model Options with Mistral Medium 3.5
Microsoft Copilot Studio has expanded its lineup of model providers by adding Mistral's Medium 3.5 to its growing list of available AI models. This move aims to meet the increasing demand for AI models that align with regional expectations around data handling and control.
Mistral Medium 3.5 is designed for long-horizon tasks, reliable tool calling, and producing structured output that downstream code can consume. The model's reasoning effort is configurable per request, allowing it to answer quick chat replies or complex agentic runs.
The addition of Mistral Medium 3.5 provides organizations in the European Union (EU) with more flexibility in how their agents are powered while keeping data processing in-region. This can help these teams avoid extra procurement overhead that comes with adding a new model provider.
Copilot Studio continues to expand its range of models available for agent development, while maintaining orchestration, governance, and lifecycle management within the platform. By offering more choice and control, Microsoft aims to enable customers to choose the right model for each scenario, meet regional and compliance requirements, and scale agents confidently.
