Breaking News: Microsoft Integrates GPT-5 into Copilot
On August 7, 2025, OpenAI officially released its latest language model, GPT-5.
Microsoft immediately rolled it out across its ecosystem — including Microsoft 365 Copilot, Copilot (personal edition), GitHub Copilot, Azure AI Foundry, and Copilot Studio.
One of the standout upgrades is the “Real-Time Router”, a system that automatically switches between a fast-response model and a high-reasoning model depending on the complexity of your query. This means more accurate answers without sacrificing speed.
Copilot vs ChatGPT Plus: Key Differences
| Feature | Microsoft Copilot (with GPT-5) | ChatGPT Plus |
|---|---|---|
| Availability & Pricing | Built into Windows 11 and web; free tier available. Some features require a Microsoft 365 license. | Paid subscription via OpenAI (monthly). API billed separately. |
| Primary Use Cases | Office docs, emails, meeting summaries, Windows assistance | Conversation, research, creative writing, coding, prompt experiments |
| Model Selection | Automatic via Real-Time Router (fast vs. reasoning models) | User chooses available models/tools (within plan limits) |
| Enterprise Data Integration | Secure access to M365 data (emails/docs/meetings) with license | No native enterprise data access; possible via custom API setups |
| Plugins / Extensions | Copilot Studio & enterprise extensions (license/permissions required) | Custom GPTs and plugins available (subject to plan/features) |
| API Access | Limited (typically through Azure services) | Full OpenAI API access (separate billing) |
| Web Browsing / Search | Bing integration; may vary by environment and policy | Browsing mode depending on plan and settings |
| File & Image Handling | Strong Office integration (summaries, drafts, edits) | File/image inputs supported (model/feature dependent) |
| Security & Governance | Enterprise policies: tenant control, auditing, compliance | Primarily individual use; enterprise needs custom governance |
| Free Tier / Limits | Free Copilot may have usage caps and feature restrictions | Paid plan still has limits; offers priority & early features |
| Best For | Windows & Microsoft 365 users; enterprise workflows | Creators, developers, researchers, power users |
| Key Caveats | Some features require licenses; depends on tenant settings | API is separate cost; external integrations require setup |
Bottom line:
Copilot is deeply integrated into Microsoft’s ecosystem and excels in business workflows, while ChatGPT Plus offers more flexibility, customization, and development options.
Are Users Actually Cancelling ChatGPT Plus?
Some early adopters on Reddit are already impressed with GPT-5 in Copilot, reporting faster performance and better document handling.
With Copilot’s free access and new capabilities, some users are considering whether the $20/month ChatGPT Plus subscription is still worth it.
Why ChatGPT Plus Still Has Value
Even with GPT-5 in Copilot, ChatGPT Plus retains advantages:
- Custom GPTs and plugins for specialized tasks
- Full API access for integration into apps and workflows
- Advanced prompt control for experimentation and creative work
For developers, researchers, and creators, these capabilities may still justify the subscription.
Before You Cancel ChatGPT Plus
- Check feature gaps — Copilot’s free tier may lack plugins, API access, or advanced customization.
- Consider future needs — You might not need API access now, but could later.
- Watch for changes — Microsoft and OpenAI may adjust features, pricing, or limits.
Tip: Make sure you compare the tools using your actual workflows before making a decision.
Looking Ahead
The GPT-5 rollout in Copilot marks a shift toward “AI as a built-in feature” on personal and work devices.
With big players like Microsoft integrating powerful AI models at no extra cost, subscription-based AI services may need to evolve their value propositions.
The real winner? Users who now have more choices than ever.
Closing Thought:
Whether you stick with ChatGPT Plus, switch to Copilot, or use both, the most important thing is to match the tool to your goals. Try them side by side, see which fits your workflow best, and don’t be afraid to switch if your needs change.
