On the Overthinking of o1-Like LLMs](https://md.research.elamur.ai/free/en/papers/chen-2024-think-that-much-2-3/)** *(2024 · 192 citations)* Reasoning models in the o1 family get better accuracy by writing very long chains of thought. This paper argues that much of that extra test-time compute is wasted. The authors call the waste "overthinking": after a model already has the right answer to a trivial question, it keeps producing new solution attempts.… 2. **[(Perhaps) Beyond Human Translation: Harnessing Multi-Agent Collaboration for Translating Ultra-Long Literary Texts](https://md.research.elamur.ai/free/en/papers/wu-2025-perhaps-beyond-human-translation-harnessing/)** *(2025 · 71 citations)* Literary translation is still hard for MT systems. Novels rely on figurative language, cultural references and a distinctive authorial style, and these become harder to handle consistently across book-length documents. The authors present TRANSAGENTS, a framework in which LLM agents play the staff of a translation… 3. **[Refuse Whenever You Feel Unsafe: Improving Safety in LLMs via Decoupled Refusal Training](https://md.research.elamur.ai/free/en/papers/yuan-2025-refuse-whenever-you-feel-unsafe/)** *(2025 · 19 citations)* Safety-tuning data for LLMs usually places refusal phrases ("Sorry", "I cannot") at the very start of the reply. ## Co-authors here 12 of 20 co-authors with a page, the most papers together first. - [Tian Liang](https://md.research.elamur.ai/free/en/authors/tian-liang/) ×2 - [Zhaopeng Tu](https://md.research.elamur.ai/free/en/authors/zhaopeng-tu/) ×2 - [Dian Yu](https://md.research.elamur.ai/free/en/authors/dian-yu/) - [Gholamreza Haffari](https://md.research.elamur.ai/free/en/authors/gholamreza-haffari/) - [Jen-tse Huang](https://md.research.elamur.ai/free/en/authors/jen-tse-huang/) - [Jianhui Pang](https://md.research.elamur.ai/free/en/authors/jianhui-pang/) - [Kaifu Zhang](https://md.research.elamur.ai/free/en/authors/kaifu-zhang/) - [Linfeng Song](https://md.research.elamur.ai/free/en/authors/linfeng-song/) - [Minghao Wu](https://md.research.elamur.ai/free/en/authors/minghao-wu/) - [Pinjia He](https://md.research.elamur.ai/free/en/authors/pinjia-he/) - [Qiuzhi Liu](https://md.research.elamur.ai/free/en/authors/qiuzhi-liu/) - [Rui Wang](https://md.research.elamur.ai/free/en/authors/rui-wang/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/): [ACL 2025](https://md.research.elamur.ai/free/en/venues/acl/2025/) - [Transactions of the Association for Computational Linguistics (TACL)](https://md.research.elamur.ai/free/en/venues/tacl/): [Transactions of the Association for Computational Linguistics (TACL) 2025](https://md.research.elamur.ai/free/en/venues/tacl/2025/) ## Cited by Papers of our library cite their works 243 times (of the 149,439 papers whose bibliographies we read); [69 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/jiahao-xu/cited-by/).
