LLMs vs. Embedding Models: Costly Trade-offs Revealed in New Research

A new research paper titled "The Embedder's Dilemma: LLMs Are Better, but at What Cost?" compares large language models (LLMs) against traditional embedding models across 37 tasks. The study found that while LLMs and embedding models perform comparably overall, LLMs are significantly more expensive and slower, costing up to 1,431 times more per benchmark pass. The research suggests a division of labor, recommending embedding models for tasks like similarity, classification, and clustering, while reserving LLMs for complex retrieval tasks. AI

IMPACT Suggests a cost-benefit analysis for AI developers choosing between LLMs and embedding models for specific tasks.
