Early Exit via Sufficiency Assessment for Efficient Reasoning](https://md.research.elamur.ai/free/en/papers/xiang-2026-when-is-thinking-enough-early/)** *(2026 · 1 citation)* Large reasoning models tend to overthink: they keep re-verifying or trying other strategies after they already have a correct solution, which wastes tokens. 2. **[When to Trust Tools? Adaptive Tool Trust Calibration For Tool-Integrated Math Reasoning](https://md.research.elamur.ai/free/en/papers/xu-2026-when-trust-tools-adaptive-tool/)** *(2026)* Tool-Integrated Reasoning (TIR) models solve math problems by interleaving reasoning with code execution. The authors show that these models often handle disagreements between their own reasoning and the tool's output poorly. They audited more than 32k trajectories with an LLM and found that most conflicts are… ## Co-authors here 7 co-authors with a page, the most papers together first. - [Juntao Li](https://md.research.elamur.ai/free/en/authors/juntao-li/) ×2 - [Min Zhang](https://md.research.elamur.ai/free/en/authors/min-zhang/) ×2 - [Yixin Ji](https://md.research.elamur.ai/free/en/authors/yixin-ji/) ×2 - [Dong Li](https://md.research.elamur.ai/free/en/authors/dong-li/) - [Jinpeng Li](https://md.research.elamur.ai/free/en/authors/jinpeng-li/) - [Peifeng Li](https://md.research.elamur.ai/free/en/authors/peifeng-li/) - [Yang Xiang](https://md.research.elamur.ai/free/en/authors/yang-xiang/) ## 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 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) - [Findings of the Association for Computational Linguistics](https://md.research.elamur.ai/free/en/venues/findings/): [Findings of the Association for Computational Linguistics 2026](https://md.research.elamur.ai/free/en/venues/findings/2026/) ## Cited by Papers of our library cite their works 1 time (of the 149,439 papers whose bibliographies we read).
