OpenAI API platform
OpenAI’s official API and developer platform, distinct from the ChatGPT consumer app.
Tasks: Coding
The OpenAI API platform is at platform.openai.com. It is the official developer site for API keys, model documentation, and account billing for API usage—separate from the ChatGPT consumer app at chatgpt.com.
Model catalogs and pricing tables live on OpenAI’s platform and should be read there. This page does not copy price lists.
Use it when you are writing software that calls OpenAI’s APIs. Protect keys, log only what you must, and review the current usage policies.
