Migration

v1 endpoints will be deprecated on December 18, 2024. Please migrate your applications before then. The migration guide is available in our docs.

assistant = client.beta.assistants.create(
    name="Math Tutor",
    instructions="You are a helpful math tutor.",
    model="gpt-4o",
    tools=[{"type": "file_search"}],
)

We'd love to hear how you're using the new features!

Streaming support is a game changer. The UX of our chatbot improved dramatically. No more waiting for full responses.

Is there a migration tool to convert v1 assistants to v2? I have about 20 assistants to migrate.

Not an automated tool, but the migration guide covers all the changes step by step. The main difference is how file search works - you'll need to create vector stores. Most other changes are additive.
