Generative pages aims to redefine how makers build with Microsoft Power Apps—bringing the power of vibe coding to enterprise development in model-driven apps. With just a few prompts, makers can generate rich, responsive pages backed by real React and TypeScript code, all while maintaining enterprise-grade governance and reliability.
Aligning to the official GPT-5 announcement yesterday, makers using generative pages will have access to new GPT-5 model, which offers significant improvements in code generation quality, performance, and reliability. To give optimal flexibility, we’ve added a model selector to the experience—allowing you to choose between GPT-4.1 and GPT-5 depending on your needs. This update started rolling out yesterday.
What’s new with GPT-5 in generative pages?
- Improved code generation quality: Better syntax, smarter layout handling, and fewer rendering errors.
- Fewer failures: Higher success rates for generated pages, even in complex scenarios.
- Enhanced performance: Faster generation times during the page creation process.

In addition to giving access to the new GPT-5 model, this release includes several minor enhancements to improve usability and reliability:
- An expanded context window to reduce lost requirements in longer sessions
- Better fallback styling to preserve model-driven app design
- Ensured retention of image attachments during retries
- More informative error messages for invalid requests
- Conditional warnings when another user is editing the same page
- Improved undo/restore behavior for error and retry scenarios
This update reflects our commitment to making AI-native app development intuitive, flexible, and enterprise-ready.
