What Does a Harness Buy? Tokens, Mostly
Yangze Liu, Zhongyi Han
A coding agent is a language model wrapped in a harness: the system prompt, the tool set, and the context management that turn a chat model into something that can work inside a re…
Asking Earns Nothing: Scoring the Decision to Act in BFCL Multi-Turn
Yangze Liu, Zhongyi Han
An agent that lacks the information it needs should ask rather than act, and the task definitions of agent leaderboards say so. BFCL multi-turn builds two of its four categories ar…
Are Coreset Selection Methods Worth Their Cost?
Yangze Liu, Zhongyi Han
Coreset selection picks a representative subset of the labeled training set to make training cheaper. However, it is usually evaluated by downstream accuracy at a fixed subset size…
Break Step: Recursive Training Resonates with Replayed Sampling Noise
Yangze Liu, Zhongyi Han
How fast does a language model degrade when trained on its own outputs? Theory traces it to gradually accumulating errors, while experiments report repeated phrases within ten gene…
A Dominant Supplier Slows Recursive Drift More Than It Steers It
Yangze Liu, Zhongyi Han
More and more of the text future language models learn from is written by a few of today's models. If one supplier writes most of a shared corpus, does it pull the models trained o…
