The coding agent describes its problem and PL returns ranked techniques with implementation steps, hyperparameters, and failure modes.

We tested it on Karpathy's autoresearch framework : where the task is to find better llm architecture and training configs. In autoresearch, the agent proposes an optimization, tries a 5 min training run, calculates the val loss and then keeps / discards if the val loss lowered / increased.

We compared a strong baseline agent (Opus 4.6 + web search) vs that same agent + Paper Lantern. - agent + Paper Lantern iterated to a config that got a much lower val loss on 5-min runs - we trained the two final configs for 2 hours : the config from Paper Lantern got a 3.2% lower val loss

Two concrete examples :

  1. Both agents tried halving the batch size. The paper-access agent pulled a 2022 paper and scaled the learning rate by 1/sqrt(2) as the paper prescribed. It worked, and further halving kept working. The web-search agent made the same batch change, got worse loss, and moved on without diagnosing the LR.

  2. The with-paper-lantern agent also implemented AdaGC (adaptive gradient clipping, arxiv 2502.11034, published Feb 2025) on the first try with no tuning. Which the baseline agent did not try at all.
