Improving Language Models by Retrieving from Trillions of Tokens
by DeepMind · free · Last verified 2026-03-17
Presents RETRO (Retrieval-Enhanced Transformers), a model that retrieves from a 2-trillion-token database at inference time via chunked cross-attention. RETRO achieves performance comparable to GPT-3 with 25× fewer parameters by leveraging retrieved passages, demonstrating that retrieval augmentation is a compute-efficient alternative to scaling.
