Does the new Threads beta support streaming chat responses?

Below is a brief explanation of how these features interact:

• Chat Completions & Streaming:
  The Chat Completions API supports streaming responses. This means that you can receive parts of the response in real time following the Server-sent events standard. For a chat app that streams responses, this is the API you’d typically use with the stream parameter enabled.

• Assistants (Runs):
  The Assistants API (sometimes referred to under the "runs" endpoints) also supports streaming in a similar fashion. Both the Chat Completions and the Assistants APIs provide helpers in their official Node and Python libraries to manage streaming.

• Threads (Beta):
  The threads beta endpoints are designed to assist with conversation management, encapsulating exchanges into a coherent thread. They are intended to structure and manage the conversation history rather than to provide streaming functionality by themselves. Essentially, threads help with organizing context but do not change how streaming works.

Conclusion:
For a run-of-the-mill chat app that streams responses, you should continue to use the Chat Completions API (or the Assistants API if that suits your use case). The new threads beta can be used in addition to structure your conversation data, but they do not provide streaming functionality on their own.

If you need an example in Python or Node.js, the official libraries include streamlined helpers to handle streaming responses.
