Frontier models struggle to identify valuable research experiments

The development
Frontier language models show modest judgment when tasked with research design, according to a new evaluation framework. Researchers gave six state-of-the-art models recent NLP papers and asked them to propose minimal experiments, forecast outcomes, and rank by value. While agent-selected experiments outperformed random selection, they failed to consistently beat human baselines like picking the first proposed idea. Only 73 of 415 proposed experiments were deemed both sound and non-obvious by auditors. The finding raises questions about whether current models can reliably identify high-impact research directions without human oversight, a critical capability for autonomous science workflows.

The rTaste framework measures research judgment through a three-step pipeline (propose, forecast, rank), but the 73/415 acceptance rate conflates two different problems: whether models can generate sound ideas versus whether they can rank ideas by impact. The summary doesn't clarify which capability actually failed.
This directly extends the SCI-AGENT-EXAM work from late October, which built systematic evaluation infrastructure for agent research tasks. Where SCI-AGENT-EXAM tested multi-step workflows, rTaste narrows focus to judgment quality on a single domain (NLP). However, the findings align with the Anthropic study showing experts misattribute AI recommendations as their own reasoning. If models can't reliably identify high-impact work, the risk isn't just bad autonomous science, it's that human researchers will adopt agent-selected experiments while believing they made the choice independently.
If the rTaste authors release their 73 'sound and non-obvious' experiments as a curated dataset and show that human researchers independently converge on the same subset at >70% agreement, the evaluation is measuring something real about research taste. If human agreement on the same task drops below 60%, the framework is measuring evaluator preference, not model failure.

New benchmark tests LLM agents on realistic scientific research workflows
Researchers have built a systematic evaluation framework for LLM agents tackling scientific research workflows, addressing a critical gap in how we measure agent capability beyond narrow task domains. SCI-AGENT-EXAM spans 120 expert-designed tasks across 11 scientific fields and seven research activity types, requiring agents to produce both executable outputs (code, scripts) and interpretive artifacts (reports,…
