Available today: GPT-5 in Microsoft Copilot Studio

Microsoft Copilot Studio users now have access to GPT-5, OpenAI’s most advanced generative AI system. This release introduces the ability to select your agent’s model for generative answers and orchestration from a curated set optimized by Microsoft. Bringing GPT-5 to Microsoft 365 Copilot and Copilot Studio on launch day demonstrates Microsoft’s commitment to providing cutting-edge AI capabilities while maintaining enterprise-grade security and support.

Real-time model routing for optimized agent responses

A key feature of GPT-5 is its real-time router, which dynamically selects the ideal model for each task or response based on your instructions and prompts:

• For simple or routine prompts, GPT-5 uses a high-throughput chat model that prioritizes speed and straightforward answers.
• For complex or open-ended tasks, GPT-5 switches to a deep reasoning model that carefully plans, gathers context, and verifies its output before responding.

Smarter orchestration and sharper agents

The orchestration model governs how an agent interprets instructions, plans actions, uses tools, and generates answers. GPT-5 enhances agent capabilities with:
• Improved reasoning in ambiguous situations to determine the best next step
• Increased coherence in multi-turn conversations
• Stronger instruction following for better overall performance
Users in early release cycle environments can now select their agent’s model in the settings:
• GPT-5 Auto: Uses the real-time router to balance speed and reasoning by switching between the high-throughput and deep reasoning models.
• GPT-5 Reasoning: Prioritizes the deep reasoning model for complex scenarios.


Powering agent tools with GPT-5

Tools enable agents to handle business processes effectively. Custom prompts, a flexible tool in Copilot Studio, allow makers to instruct AI models to complete subtasks such as formatting documents or extracting invoice numbers. Makers in early release environments can now choose between GPT-5’s high-throughput and deep reasoning models for custom prompt tools. Benefits include:
• Longer context support and improved document understanding with the high-throughput model, delivering natural, context-aware, and faster responses.
• Multi-step logic and enhanced accuracy for complex planning and analysis tasks with the deep reasoning model.


Getting started with GPT-5 in Copilot Studio

GPT-5 is available today as an experimental AI system for agents built in early release cycle environments, allowing makers to test and upgrade existing agents easily. Copilot Studio also offers:
• Agent-specific fine tuning
• Global GPU infrastructure management
• Flexibility to bring your own fine-tuned models hosted in Azure AI Foundry Models
Full rollout to all environments is expected later this month. Learn more about early release cycle environments and agent model selection. Read more about GPT-5 in Microsoft 365 Copilot. Try Copilot Studio
