Researchers have developed a new method for training text embedding models that combines distillation techniques with task-specific contrastive loss. This approach aims to create compact, high-performance embedding models that outperform purely contrastive or distillation-based methods. The resulting models, jina-embeddings-v5-text-small and jina-embeddings-v5-text-nano, achieve state-of-the-art benchmark scores for their size and support long texts with robust embeddings. AI
