 we recommend using [python-dotenv](https://pypi.org/project/python-dotenv/)
 to add `OPENAI_API_KEY="My API Key"` to your `.env` file

-### Polling Helpers
-
-When interacting with the API some actions such as starting a Run and adding files to vector stores are asynchronous and take time to complete. The SDK includes
-helper functions which will poll the status until it reaches a terminal state and then return the resulting object.
-If an API method results in an action that could benefit from polling there will be a corresponding version of the
-method ending in '\_and_poll'.
-
-For instance to create a Run and poll until it reaches a terminal state you can run:
-
-```python
-run = client.beta.threads.runs.create_and_poll(
-    thread_id=thread.id,
-    assistant_id=assistant.id,
-)
-```
-
-More information on the lifecycle of a Run can be found in the [Run Lifecycle Documentation](https://platform.openai.com/docs/assistants/how-it-works/run-lifecycle)
-
-### Bulk Upload Helpers
-
-When creating and interacting with vector stores, you can use polling helpers to monitor the status of operations.
-For convenience, we also provide a bulk upload helper to allow you to simultaneously upload several files at once.
-
-```python
-sample_files = [Path("sample-paper.pdf"), ...]
-
-batch = await client.vector_stores.file_batches.upload_and_poll(
-    store.id,
-    files=sample_files,
-)
-```
-
-### Streaming Helpers
-
-The SDK also includes helpers to process streams and handle incoming events.
-
-```python
-with client.beta.threads.runs.stream(
-    thread_id=thread.id,
-    assistant_id=assistant.id,
-    instructions="Please address the user as Jane Doe. The user has a premium account.",
-) as stream:
-    for event in stream:
-        # Print the text from text delta events
-        if event.type == "thread.message.delta" and event.data.delta.content:
-            print(event.data.delta.content[0].text)
-```
-
-More information on streaming helpers can be found in the dedicated documentation: [helpers.md](helpers.md)

-We also expose a global client instance that is accessible in a similar fashion to versions prior to v1.

-The API is the exact same as the standard client instance-based API.
-
-This is intended to be used within REPLs or notebooks for faster iteration, **not** in application code.
-
-We recommend that you always instantiate a client (e.g., with `client = OpenAI()`) in application code because:
-
-- It can be difficult to reason about where client options are configured
-- It's not possible to change certain client options without potentially causing race conditions
-- It's harder to mock for testing purposes
-- It's not possible to control cleanup of network connections
