PromptEmbedder:: Efficient and Transferable Text Embedding via Dual-LLM Soft Prompting
PromptEmbedder introduces a dual-LLM framework that decouples text embedding from specific model architectures, achieving comparable performance to LoRA while reducing GPU memory by 40% and accelerating training 3.7x. The innovation enables efficient transfer across different LLM backbones by retraining only a lightweight alignment matrix rather than entire models.
