assistants API
An API for creating persistent assistants that remember conversation history, manage state, and have built-in tool support.
Think of it like
Like ChatGPT but for your application—conversation continuity, file upload, tool calls, all via API.
Example
Create an assistant that's a tax advisor. Upload tax documents via API, start a thread (conversation), send messages. The assistant remembers context and has access to a calculator tool.
How it actually works
The assistants API abstracts conversation state management. You create an assistant once, start threads with users, send messages, and the API handles token limit management and tool invocation. Works well for chatbot-like applications but can be less flexible than raw chat API.
For product teams

For engineers
