This matters most for reasoning models that produce long outputs. StepFun argues that parameter counts predict this cost poorly. Their paper presents Step-3, a 321B-parameter VLM that activates 38B parameters per… 2. **[WavRAG: Audio-Integrated Retrieval Augmented Generation for Spoken Dialogue Models](https://md.research.elamur.ai/free/en/papers/chen-2025-wavrag-audio-integrated-retrieval-augmented/)** *(2025 · 22 citations)* Most retrieval-augmented generation (RAG) systems assume text input, so spoken dialogue models usually reach them through a cascaded ASR step. ## Co-authors here 9 co-authors with a page, the most papers together first. - [Bin Wang](https://md.research.elamur.ai/free/en/authors/bin-wang/) - [Changyi Wan](https://md.research.elamur.ai/free/en/authors/changyi-wan/) - [Jin Xu](https://md.research.elamur.ai/free/en/authors/jin-xu/) - [Jinzheng He](https://md.research.elamur.ai/free/en/authors/jinzheng-he/) - [Nuo Chen](https://md.research.elamur.ai/free/en/authors/nuo-chen/) - [Shengpeng Ji](https://md.research.elamur.ai/free/en/authors/shengpeng-ji/) - [Yifu Chen](https://md.research.elamur.ai/free/en/authors/yifu-chen/) - [Zhou Zhao](https://md.research.elamur.ai/free/en/authors/zhou-zhao/) - [Ziqing Wang](https://md.research.elamur.ai/free/en/authors/ziqing-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/) ## Cited by Papers of our library cite their works 39 times (of the 149,439 papers whose bibliographies we read); [10 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/siyu-chen/cited-by/).
