GPT-5 is now also available in Copilot
Microsoft is integrating GPT-5 into its Copilot ecosystem. This integration applies to both Microsoft 365 Copilot and Copilot Studio and is designed to significantly enhance the power of AI assistance. GPT-5 provides users with improved reasoning capabilities and more precise, context-aware responses.
A key element of this update is Smart Mode, which automatically detects whether a request requires quick results or in-depth analysis. This allows Copilot to handle complex queries more effectively, deliver more relevant information, and analyze content across sources such as emails, documents, and files. The goal is to optimize the handling of demanding tasks—from creating detailed reports to conducting data-driven analyses.
Added value: Productivity 
Scenario: Information Processing 
Reading time: 5 minutes 
Difficulty: Beginner
Evaluation of the function
How does the function perform?
How it works
The model is already available in the soluzione tenant. In the locally installed Copilot app, it can be tested.
To use GPT-5, simply click the button in front of the prompt.
Whether the marketing promise will hold true will become clear in the coming days. Initial tests, however, suggest that Copilot does respond faster and—depending on the request—automatically selects the appropriate mode. This can be seen in the status information within the chat window.
General notes
Access to GPT-5 depends on licensing status:
- Priority Access: M365 Copilot license holders receive guaranteed stable performance—even during high demand.
- Standard Access: For Copilot Chat users, performance depends on available capacity; in case of overload, an in-app notification is displayed—ongoing tasks are not interrupted.
How does Copilot work with the new model?
Of course, we asked ourselves how Copilot handles tasks with the new model. Microsoft has published the following information: Link to source
Copilot analyzes your question or request—including any attached files for context—to determine your needs. Based on the complexity, Copilot Chat then selects the optimal response.
Quick answers: For simple, factual questions, Copilot responds quickly with clear, precise information.
Thoughtful analysis: For more complex or multi-step questions, Copilot takes a little more time to think the task through thoroughly and lays out its reasoning step by step.
In-depth research through agents: For complex, research-intensive topics, you can use the Researcher and Analyst agents in Copilot. They consolidate information from your M365 environment and trusted sources, organize it into a structured response, and provide appropriate source references.
Advantages according to Copilot
We asked Copilot what advantages the new model brings to our daily work, and here’s the response:
- Higher accuracy and contextual understanding
- GPT-5 can process longer and more complex contexts more effectively.
- Fewer hallucinations and more precise answers, especially for specialized topics.
- Improved multimodality
- You can analyze and interpret not only text but also images (e.g., screenshots, diagrams).
- Soon: expanded support for audio and video (depending on the platform).
- Better adaptation to your style
- GPT-5 is more capable of following your writing style, tone, and guidelines (e.g., avoiding word duplication, ensuring clear communication).
- More efficiency with complex tasks
- Better performance in data analysis, code generation, and automation.
- Can handle larger data sets in a single run.
- Creativity & structure
- Stronger at brainstorming, concept development, and storytelling.
- Provides structured outputs (e.g., tables, lists) more consistently.
Conclusion
The integration of GPT-5 into Microsoft Copilot marks a significant advancement in AI assistance. Enhanced reasoning capabilities and a deeper understanding of complex contexts make Copilot a more powerful assistant, adapting flexibly to any task thanks to Smart Mode. For both businesses and individuals, this means higher productivity, more efficient workflows, and new opportunities to develop personalized AI solutions.
With GPT-5, Copilot is not only a tool for everyday work but also a clear indicator of the ongoing evolution toward smarter and more accessible assistance systems. Those who start testing it now will immediately benefit from more precise answers, better-informed decisions, and noticeable time savings.
