What makes a great ChatGPT app | OpenAI Developers

What this post added

This post introduces and defines ChatGPT Apps as a new way to integrate external products into ChatGPT conversations. It shifts the paradigm from porting entire products to exposing specific, well-defined capabilities (Know, Do, Show) that the model can orchestrate. The post provides practical guidance on selecting use cases, designing for conversational discovery, and defining clear APIs for these capabilities, emphasizing that the value lies in discrete operations that extend the model's reach into data, actions, and structured UIs, thereby enhancing agentic capabilities.
