## Papers

The most cited first (OpenAlex and our library).

1. **[A Survey on Data Selection for Language Models](https://md.research.elamur.ai/free/en/papers/albalak-2024-survey-data-selection-language-models/)** *(2024 · 85 citations)* Large language models depend on huge web-scale corpora, but using every available document is often wasteful or harmful because text quality varies widely.
2. **[ThinkPrune: Pruning Long Chain-of-Thought of LLMs via Reinforcement Learning](https://md.research.elamur.ai/free/en/papers/hou-2025-thinkprune-pruning-long-chain-thought/)** *(2025 · 64 citations)* Reasoning models trained to produce long chains of thought often generate redundant, inefficient reasoning, which inflates inference cost.
