  1. Do All Languages Cost the Same? Tokenization in the Era of Commercial Language Models (2023 · 164 citations)
    Commercial LM APIs bill per token, but how many tokens a text needs depends on the tokenizer and its training data.
  2. WildTeaming at Scale: From In-the-Wild Jailbreaks to (Adversarially) Safer Language Models (2024 · 89 citations)
    Frontier LLMs can still be jailbroken, and open safety-training data is scarce, since even open-weight models rarely publish theirs.
  3. Language Generation Models Can Cause Harm: So What Can We Do About It? An Actionable Survey (2023 · 87 citations)
    Much has been written about the dangers of large text generators, but practical ways to counter them were scattered across separate research communities.
  4. Minding Language Models' (Lack of) Theory of Mind: A Plug-and-Play Multi-Character Belief Tracker (2023 · 74 citations)
    Large language models still handle theory of mind (ToM) poorly. They struggle to track what each character in a story believes, especially when a belief is false, and what one character assumes about another's beliefs. Earlier fixes trained models on templated benchmarks, and those models tend to exploit dataset…
