## Papers

The most cited first (OpenAlex and our library).

1. **[Contrastive Decoding Improves Reasoning in Large Language Models](https://md.research.elamur.ai/free/en/papers/o-brien-2023-contrastive-decoding-improves-reasoning-large/)** *(2023 · 67 citations)* LLMs are usually decoded differently depending on the task: open-ended writing relies on truncated sampling, while reasoning tasks typically use greedy decoding.
2. **[Shepherd: A Critic for Language Model Generation](https://md.research.elamur.ai/free/en/papers/wang-2023-shepherd-critic-language-model-generation/)** *(2023 · 59 citations)* Shepherd tackles the problem of automatically critiquing text produced by large language models, which still often generate false or incoherent answers.
3. **[Adaptive Originality Filtering: Rejection Based Prompting and RiddleScore for Culturally Grounded Multilingual Riddle Generation](https://md.research.elamur.ai/free/en/papers/le-2025-adaptive-originality-filtering-rejection-based/)** *(2025 · 1 citation)* When LLMs are asked to write riddles in several languages, they tend to reuse familiar templates or repeat riddles they memorized during pretraining.
