dspy.Prediction

dspy.Prediction(*args, **kwargs)

Bases: Example

A prediction object that contains the output of a DSPy module.

Prediction inherits from Example.

To allow feedback-augmented scores, Prediction supports comparison operations (<, >, <=, >=) for Predictions with a score field. The comparison operations compare the 'score' values as floats. For equality comparison, Predictions are equal if their underlying data stores are equal (inherited from Example).

Arithmetic operations (+, /, etc.) are also supported for Predictions with a 'score' field, operating on the score value.
