classifier

Classifier backed by Jev, TypeSafe’s hosted classification model.

JevClassifier turns each question into a request and each reply into a result, through a JevClient.

pipecat.classifiers.jev.classifier.JEV_MAX_CHOICE_OPTIONS = 255

The most options Jev takes in one choice question.

class pipecat.classifiers.jev.classifier.JevClassifier(*, api_key: str | None = None, client: JevClient | None = None, model: str = 'jev-1.13.0', base_url: str = 'https://api.typesafe.ai', timeout: float = 10.0, **kwargs)

Bases: BaseClassifier

Answers questions by asking Jev.

Jev’s probabilities are calibrated. Build one with an API key to get a client of its own, or pass a JevClient to share one between several classifiers. A client the classifier created is closed in cleanup(); a shared one is left to whoever made it.

Example:

client = JevClient(api_key=os.getenv("TYPESAFE_API_KEY"))
turn_classifier = JevClassifier(client=client)
voicemail_classifier = JevClassifier(client=client)

__init__(*, api_key: str | None = None, client: JevClient | None = None, model: str = 'jev-1.13.0', base_url: str = 'https://api.typesafe.ai', timeout: float = 10.0, **kwargs)

Initialize the classifier.

Parameters:

• api_key – Jev API key, when the classifier should have a client of its own.

• client – A client to share. One of api_key and client is required.

• model – The Jev model a client of its own asks.

• base_url – Where a client of its own sends its questions.

• timeout – Seconds a client of its own waits for an answer.

• **kwargs – Additional arguments passed to the parent class.

property client: JevClient

The client this classifier asks through.

async setup(task_manager: BaseTaskManager)

Open the connection to Jev ahead of the first question.

A connection that cannot be opened now is only a warning: the first question opens it itself.

Parameters:

task_manager – The task manager of the owner.

async cleanup()

Close the client if this classifier created it.

property model: str

The Jev model the questions go to.
