Microsoft is introducing a new feature called Smart Mode to its Copilot assistant, empowering the AI to adapt its thinking style—whether fast or thoughtful—based on the complexity of your task. Code-level discoveries and official hints strongly suggest this mode is powered by GPT‑5, which OpenAI is expected to unveil in early August 2025.
What is Copilot’s ‘Smart Mode’?
- A new option in Copilot’s model selector menu that reportedly uses GPT‑5 to automatically decide between fast, light responses or deep, reasoning-based answers based on user queries.
- It replaces manual mode selection (like ‘Quick Response’ or ‘Think Deeper’) with an integrated intelligence that adapts to the task at hand.
- Code snippets in Copilot reveal that Smart Mode is already present but still hidden and defaults to fast-style responses pre-GPT‑5 rollout.
Why This Marks a Major Shift
Unified Reasoning & Performance
GPT‑5 is expected to unify OpenAI’s non‑reasoning GPT models and “o-series” reasoning models into a single system. Smart Mode demonstrates how Microsoft plans to leverage that unified architecture.
Simplified User Experience
Users no longer need to choose between different response styles. Smart Mode selects the optimal strategy automatically—ideal for casual users and enterprise workers alike.
Seamless Enterprise Integration
Available in both consumer and Microsoft 365 deployments of Copilot, Smart Mode positions Microsoft to deliver GPT‑5’s full capabilities across its ecosystem immediately.
Timeline & Readiness
- Microsoft was seen embedding GPT‑5 references in Copilot UI code as early as July 24–25, 2025, as reported by TestingCatalog and The Verge.
- GPT‑5’s official launch is expected in early August 2025, after previous delays due to performance tuning.
- Smart Mode likely aims to debut in lockstep with GPT‑5—or shortly thereafter—as part of Microsoft’s coordinated rollout strategy.
How It Compares: Copilot Modes
| Mode | Behavior | Intended Use |
| Quick Response | Fast, concise answers | Simple queries |
| Think Deeper | Multi-step reasoning by o1 model | Complex tasks, coding, logic |
| Deep Research | Specialized research capabilities | Document analysis, summaries |
| Smart Mode | AI picks fastest or deepest mode | Adaptive intelligence—user agnostic |
Smart Mode aims to eliminate mode-selection friction, adapting responses automatically.
Sam Altman & GPT‑5 Context
OpenAI CEO Sam Altman has publicly criticized the idea of manual model selection, calling it outdated. He described GPT‑5 as a move toward “magic unified intelligence,” where a single model handles both reasoning and non-reasoning tasks.
GPT‑5 is expected to debut in variants—mini, nano, and full-scale—with improved contextual memory, reasoning power, and overall coherence.
Early Signals from Code & Testing
- TestingCatalog reports revealed that Smart Mode appears as a hidden option in Copilot’s dropdown UI labeled “Smart (GPT‑5)”. The description reads: “think quickly or deeply.”
- Though not yet functional in public builds, Microsoft engineers were able to force Smart Mode “on,” showing it defaults to fast-mode behavior without GPT‑5 active.
- Additional sources confirm that Microsoft’s consumer and business Copilot versions actively reference Smart Mode, though GPT‑5 remains unconfirmed in output responses.
Strengths & Early Limitations
Advantages
- Streamlined experience with no mode switching
- Unified reasoning and speed in one assistant
- Enterprise-ready deployment across M365 and Windows
- Large-scale adaptability for diverse user needs
Caveats
- Feature is still hidden and not yet available in public builds
- GPT‑5 integration not fully confirmed until launch
- Missing override option—users may want control over mode behavior
- Privacy & accuracy concerns remain as adaptive reasoning becomes broader.
Use Cases & Future Impact
Smart Mode’s AI adaptability has implications for multiple fields:
- Knowledge work: analysts, managers, or students who juggle quick memos and deep research
- Customer and enterprise support: switching dynamically between fast FAQs and reasoning-based support
- Creative workflows: from casual brainstorming to structured planning—all from one interface
Ultimately, Smart Mode helps make Copilot appear smarter, not just faster or deeper—it becomes contextually intuitive.
Final Thoughts
Copilot’s Smart Mode, aligned with GPT‑5’s unified reasoning architecture, could redefine how AI assistants operate. By removing friction in mode selection and matching response depth to user needs dynamically, Microsoft aims to deliver a more intuitive, context-aware assistant that “just works.”
Once GPT‑5 officially launches (expected early August 2025), Smart Mode will likely become available broadly across Microsoft services—reshaping workflows in education, research, productivity, and everyday AI use.

FAQs
What is Smart Mode in Copilot?
A new AI assistant mode that uses OpenAI’s GPT-5 to automatically decide between quick-text responses or multi-step reasoning—without requiring users to pick a mode manually.
When will GPT‑5 launch?
OpenAI plans to release GPT‑5 in early August 2025, after delaying its summer timeline.
Does Copilot already run GPT‑5?
Not yet. Smart Mode references GPT‑5 are present in Copilot code, but behavior currently defaults to GPT‑4 until the model launch.
Will Smart Mode replace other modes?
Possibly—Microsoft intends Smart Mode to unify or streamline reasoning and speed-focused responses, reducing the need for manual mode selection.
Will enterprises get Smart Mode early?
Enterprise and consumer versions of Copilot both reference Smart Mode in previews. Once GPT-5 becomes available, the feature is expected to make its debut.
