That is a problem for companies that cannot send internal workflows and data to external services. The authors ask whether open-source LLMs can match closed models at turning natural-language goals into executable API calls without heavy human effort. 2. **[Mitigating Structural Knowledge Collapse in Domain-Specific LLMs via Morpheme-Aware KV-Aggregation](https://md.research.elamur.ai/free/en/papers/si-2026-mitigating-structural-knowledge-collapse-domain/)** *(2026)* Subword tokenizers such as BPE often split specialized medical and legal terms (e.g., Hydrochlorothiazide) into pieces that do not match their morphemes. ## Co-authors here 4 co-authors with a page, the most papers together first. - [Bo Li](https://md.research.elamur.ai/free/en/authors/bo-li/) - [Fei Qing Wu](https://md.research.elamur.ai/free/en/authors/fei-qing-wu/) - [Jian Zhang](https://md.research.elamur.ai/free/en/authors/jian-zhang/) - [Qiantong Xu](https://md.research.elamur.ai/free/en/authors/qiantong-xu/) ## 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/) ## Cited by Papers of our library cite their works 82 times (of the 149,439 papers whose bibliographies we read); [25 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/zhengyu-chen/cited-by/).
