https://platform.openai.com/docs/api-reference/assistants-streaming
We've also improved some of the names for the types in
the assistants beta, non exhaustive list:
- `CodeToolCall` -> `CodeInterpreterToolCall`
- `MessageContentImageFile` -> `ImageFileContentBlock`
- `MessageContentText` -> `TextContentBlock`
- `ThreadMessage` -> `Message`
- `ThreadMessageDeleted` -> `MessageDeleted`
