Hello!
I’m a new developer experimenting with the Assistant API for a project and have some questions regarding thread management and context handling:
-
Regarding threads, I understand that the conversation context is preserved within each thread. Does this mean that each API call accumulates more tokens from previous prompts until reaching a limit (with earlier context being truncated), or is the context managed in a way that avoids consuming tokens from past prompts?
-
For horizontal scaling to support multiple users, my idea is to have a single assistant instance with a dedicated thread for each user. Is this approach feasible, and what limitations might I encounter? I've been unable to find detailed information on this.
-
Is there a way to programmatically “clean” or reset a thread (for example, via the playground) so that its context is cleared?
Thanks for your insights and feedback.

Below are detailed answers to your questions regarding how Assistant API handles threads and context management:
1. Does thread context lead to increasing token consumption with each API call?
Assistant threads hold the conversation state by storing prior messages and content parts. This means that each API call includes previous exchanges as part of the context. In many language model integrations, this accumulated context can contribute to token usage until you hit the model’s token limit, at which point earlier prompts may be truncated. The system doesn’t automatically filter out previous prompts unless you intervene; it preserves the conversation history to maintain context for continuity. You may need to manage or prune the conversation history if you’d like to control token consumption over time.
2. Can I scale horizontally with one assistant per user (one thread per user)?
Yes, it is possible to create a single assistant instance that hosts multiple threads—one per user. The design of the Assistant API allows your application to manage multiple conversation threads simultaneously. The hierarchical context system (Assistant Context wrapping multiple Thread Contexts) is specifically meant to support multi-user or multi-threaded scenarios. Just keep in mind that you’ll need to manage user sessions effectively so that thread states remain isolated for each user. This is generally handled at the application or backend level.
3. Is it possible to “clean” or “empty” threads in code (e.g., in the playground)?
Yes, you can clear the conversation context by programmatically switching to a new thread or resetting the current thread’s state. The API provides functions (such as one that switches to a new thread) designed to help you “clean” or start with an empty context. This can be useful in playground scenarios or other instances where you'd like to restart the conversation history without reloading the entire app.
These answers should give you a starting point for implementing and scaling the Assistant API in your projects. Happy coding!
