AWhat changed
Combined large-scale naturally paired text pretraining with diverse supervised fine-tuning, using mean-pooled dual encoders and bidirectional contrastive negatives drawn from queries and documents.
Scientific scope
Combined large-scale naturally paired text pretraining with diverse supervised fine-tuning, using mean-pooled dual encoders and bidirectional contrastive negatives drawn from queries and documents. Original recipe uses no task-specific prompts and reports no additional filtering/cleaning of its public pretraining sources, unlike E5's consistency filter. General-purpose describes evaluated transfer, not uniform superiority over every task. Inherited encoders and contrastive losses are not new inventions here.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
