Session Duration and Thread Limits for ChatGPT's Assistant API

I have a couple of questions regarding the openai’s Assistant API:

  1. Session Duration: How long can the ChatGPT Assistant API maintain a conversation? Are there any specific limits or best practices for managing the duration of a conversation?
  2. Thread Limits: How many threads can be created per organization using the openai’s Assistant API? Is there a maximum number of threads or any guidelines on managing them?

Thank you for your help!
