Linear Recurrence vs. Transformer: Efficiency Gains for Decision Models

A researcher trained two 15 million parameter "decision-only" models, one using linear recurrence and the other using Transformer attention, to compare their performance on a long-context retrieval task. While both models achieved similar accuracy, with the Transformer performing slightly better, the linear recurrence model demonstrated significantly lower latency and training costs, especially at longer context lengths. The study suggests that for smaller decision-focused models, the choice of architecture impacts efficiency more than accuracy, particularly when dealing with tasks that do not require complex generative capabilities.

    I trained a 15M "decision-only" model two ways — linear recurrence vs Transformer attention. Accuracy was a coin flip; latency and training cost weren't.[R]
