Tokenization in the Era of Commercial Language Models](https://md.research.elamur.ai/free/en/papers/ahia-2023-do-all-languages-cost-same/)** *(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](https://md.research.elamur.ai/free/en/papers/jiang-2024-wildteaming-scale-wild-jailbreaks-adversarially/)** *(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](https://md.research.elamur.ai/free/en/papers/kumar-2023-language-generation-models-can-cause/)** *(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](https://md.research.elamur.ai/free/en/papers/sclar-2023-minding-language-models-lack-theory/)** *(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… ## All works 7 works of theirs in our library, the most cited first; 4 with a page here, the others link their original until we summarise them. 1. **[Do All Languages Cost the Same?
