About
SGPT (GPT Sentence Embeddings for Semantic Search) is an open-source tool that provides code, results, and pre-trained models for applying GPT models as Bi-Encoders or Cross-Encoders for symmetric or asymmetric search. SGPT-BE generates semantically meaningful sentence embeddings through contrastive fine-tuning of bias tensors and position-weighted mean pooling. SGPT-CE utilizes log probabilities from GPT models without requiring any fine-tuning. The project offers easy integration with Sentence Transformers and provides multilingual BLOOM SGPT models. Recent updates include GRIT & GritLM, which unify various SGPT functionalities into single, higher-performing models, and improved 5.8B Bi-Encoder models with better performance on USEB and BEIR benchmarks.
