WHALE: A Simple Recipe for Joint Harness-Weight Optimization

Haechan Kim, Yoonho Lee, Gisang Lee +2

Agent performance depends jointly on the model parameters and the executable harness code that manages context and control flow. Optimizing either component in isolation can leave…

SPIRAL: Learning to Search and Aggregate

Jubayer Ibn Hamid, Ifdita Hasan Orney, Michael Y. Li +5

Language model reasoning can be substantially improved at test time via scaffolds that scale inference compute across different primitives -- sequential reasoning within a trace, i…

Meta-Harness: End-to-End Optimization of Model Harnesses

Yoonho Lee, Roshen Nair, Qizheng Zhang +3

The performance of large language model (LLM) systems depends not only on model weights, but also on their harness: the code that determines what information to store, retrieve, an…

Feedback Descent: Open-Ended Text Optimization via Pairwise Comparison

Yoonho Lee, Joseph Boen, Chelsea Finn

We introduce \textit{Feedback Descent}, a framework that optimizes text artifacts -- prompts, code, and molecules -- through structured textual feedback, rather than relying solely…

RLAD: Training LLMs to Discover Abstractions for Solving Reasoning Problems

Yuxiao Qu, Anikait Singh, Yoonho Lee +4

Reasoning requires going beyond pattern matching or memorization of solutions to identify and implement "algorithmic procedures" that can be used to deduce answers to hard problems…

Curating Demonstrations using Online Experience

Annie S. Chen, Alec M. Lessing, Yuejiang Liu +1

Many robot demonstration datasets contain heterogeneous demonstrations of varying quality. This heterogeneity may benefit policy pre-training, but can hinder robot performance when…
