Microsoft Copilot Studio now offers GPT-5, enabling smarter AI agents with real-time model selection and enhanced reasoning capabilities.

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 highlights Microsoft's commitment to keeping customers at the forefront of AI innovation while ensuring security and support within the Microsoft ecosystem.

Real-time model selection with GPT-5

A unique feature of GPT-5 is its real-time router, which uses your instructions and prompts to select the ideal model for each task or response:
  • For simple or routine prompts, GPT-5’s high-throughput chat model is used, prioritizing speed and straightforward answers.
  • For complex or open-ended steps, GPT-5’s deep reasoning model takes its time to plan, gather context, and verify its responses for thoroughness.
  • GPT-5 enhances agent orchestration and summarization

    The orchestration model determines how an agent interprets instructions, plans, uses tools, and generates answers. GPT-5 improves agent reasoning in ambiguous situations, coherence in multi-turn conversations, and instruction following, resulting in sharper agent performance. Starting today, makers in early release cycle environments can select their agent’s model in the settings:
  • GPT-5 Auto uses the real-time router to balance speed and planning by choosing between the high-throughput or 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 apply AI models with specific instructions for sub-tasks like document creation or invoice extraction. Makers in early release environments can now choose GPT-5’s high-throughput or deep reasoning models for custom prompt tools. The high-throughput model offers faster, context-aware responses with longer context support and improved document understanding. The deep reasoning model excels at multi-step logic for complex tasks like planning and analysis with greater accuracy. Selecting GPT-5 Chat Model for Prompt Tools

    Get started with GPT-5 in Copilot Studio today

    GPT-5 in Copilot Studio is available as an experimental AI system for agents built in early release cycle environments, allowing makers to test new and existing agents. The platform offers ongoing optimizations such as agent-specific fine tuning, global GPU infrastructure management, and easy upgrades to new models. Additionally, makers can bring their fine-tuned models hosted in Azure AI Foundry Models. Microsoft plans to roll out GPT-5 in Copilot Studio to all environments later this month.

    Frequently Asked Questions

    What is GPT-5 and why is it significant for Microsoft Copilot Studio?

    GPT-5 is OpenAI's most advanced generative AI system. Its integration into Microsoft Copilot Studio allows users to select GPT-5 for their agents, enhancing generative answers and orchestration capabilities with two distinct models: a high-throughput chat model for speed and a deep reasoning model for complex tasks.

    How does the real-time router in GPT-5 work?

    The real-time router intelligently selects the appropriate GPT-5 model based on the prompt's complexity. For simple, routine prompts, it uses the high-throughput chat model for quick responses. For complex or open-ended tasks, it switches to the deep reasoning model to provide more thorough and planned answers.

    What improvements does GPT-5 bring to agent orchestration?

    GPT-5 enhances agent orchestration by improving reasoning in ambiguous situations, ensuring coherence in multi-turn conversations, and providing better instruction following. This leads to sharper and more effective agent performance.

    What are the available model selection options for agents in Copilot Studio?

    Makers can choose between "GPT-5 Auto," which utilizes the real-time router to balance speed and reasoning, or "GPT-5 Reasoning," which prioritizes the deep reasoning model for complex scenarios.

    How does GPT-5 benefit custom prompt tools?

    For custom prompt tools, GPT-5 offers two models: the high-throughput model for faster, context-aware responses with enhanced document understanding, and the deep reasoning model for complex tasks requiring multi-step logic and greater accuracy.

    When will GPT-5 be available in all Microsoft Copilot Studio environments?

    GPT-5 is currently available as an experimental AI system for agents built in early release cycle environments. Microsoft plans to roll it out to all environments later this month.

    Crypto Market AI's Take
