A tiny LoRA intervention unlocks deep reference-following in transformers

Thirteen base models reliably follow only 1.4–3.6 lines; a rank-8 LoRA at one early layer boosts exact accuracy on 24-line chains from 15.5% to 99% in Qwen3-8B.

The authors show that pretrained transformers underuse their depth for in-context reference following, with thirteen models reliably tracking only 2-3 lines.
