zero-shot-classification model by undefined. 2,58,745 downloads.

Unique: Uses a distilled cross-encoder architecture (MiniLMv2-L6-H768, 22.7M parameters) that jointly encodes premise-hypothesis pairs through a single transformer pass, enabling direct interaction modeling while maintaining <100ms inference latency on CPU — a balance point between bi-encoder speed and cross-encoder accuracy that most alternatives sacrifice

vs others: Faster than full-size cross-encoder NLI models (RoBERTa-Large) by 3-5x due to distillation, yet maintains competitive zero-shot entailment accuracy; slower than bi-encoder alternatives for ranking but captures semantic interactions that bi-encoders miss
