🚨New paper: Reward Models (RMs) are used to align LLMs, but can they be steered toward user-specific value/style preferences?
With EVALUESTEER, we find even the best RMs we tested exhibit their own value/style biases, and are unable to align with a user >25% of the time. 🧵

Please reach out if you'd like to chat about this work! We hope ConflictScope helps researchers study how models handle value conflicts that matter to their communities.

ConflictScope can also be used to evaluate different approaches toward steering models. We find that including detailed target rankings in system prompts consistently improves model alignment with the target ranking while under conflict, but with plenty of room for improvement.

We find significant shifts between models’ expressed and revealed preferences under conflict! Models say they prefer actions that support protective values (e.g. harmlessness) when asked directly, but support personal values (e.g. helpfulness) in more realistic evaluations.

To address issues with multiple-choice evaluation, we focus on open-ended evaluation with a simulated user. Annotation studies show strong correlation between LLM and human judgments of which action a model took in a given scenario, allowing us to automate open-ended evaluations.

We introduce new metrics to measure how morally challenging a dataset is for models. We find that ConflictScope produces datasets that elicit more disagreement and stronger preferences than moral dilemma datasets, while alignment data frequently elicits indifference from models.

Given a set of values, ConflictScope generates scenarios in which an LLM-based assistant faces a conflict between a pair of values in the set. It then evaluates which value a target LLM supports more in each scenario before combining scenario-level judgments into a value ranking.

🚨New Paper: LLM developers aim to align models with values like helpfulness or harmlessness. But when these conflict, which values do models choose to support? We introduce ConflictScope, a fully-automated evaluation pipeline that reveals how models rank values under conflict.

Placing LLMs in simulated markets helps us quantitatively and qualitatively measure their propensity to collude, as well as how environmental changes affect this. Read below or find @veronateo.bsky.social at the ICML multi-agent systems workshop to learn more!

PRISM has preference scores for different models that you can convert into pairwise labels
