Send this event to clear the audio bytes in the buffer. The server will
respond with an input_audio_buffer.cleared event.

Send this event to commit the user input audio buffer, which will create a
new user message item in the conversation. This event will produce an error
if the input audio buffer is empty. When in Server VAD mode, the client does
not need to send this event, the server will commit the audio buffer
automatically.

Committing the input audio buffer will trigger input audio transcription
(if enabled in session configuration), but it will not create a response
from the model. The server will respond with an input_audio_buffer.committed
event.

Send this event to cancel an in-progress response. The server will respond
with a response.cancelled event or an error if there is no response to
cancel.

This event instructs the server to create a Response, which means triggering
model inference. When in Server VAD mode, the server will create Responses
automatically.

A Response will include at least one Item, and may have two, in which case
the second will be a function call. These Items will be appended to the
conversation history.

The server will respond with a response.created event, events for Items
and content created, and finally a response.done event to indicate the
Response is complete.

The response.create event includes inference configuration like
instructions, and temperature. These fields will override the Session’s
configuration for this Response only.

Send this event to update the session’s default configuration. The client may
send this event at any time to update the session configuration, and any
field may be updated at any time, except for “voice”. The server will respond
with a session.updated event that shows the full effective configuration.
Only fields that are present are updated, thus the correct way to clear a
field like “instructions” is to pass an empty string.
