calibration — How well a model's confidence matches reality — a calibrated model saying "90% sure" is right about 90% of the time.
hallucination — When a model states something false with full confidence — inventing facts, citations, or APIs that don't exist.
Why it matters
Jev is a non-generative model built purely for fast, calibrationHow well a model's confidence matches reality — a calibrated model saying "90% sure" is right about 90% of the time.Full definition → classification and routing decisions, claimed to run over 100x faster and 200x cheaper than small frontier LLMs, useful as a cheap decision layer in front of slower reasoning models.
