Work

• Designed and built the retrieval experience in LanceDB: reranking, hybrid search, and multivector retrieval.
• Drove the ecosystem integrations that put the product where developers already build: native Lance support on the Hugging Face Hub, LlamaIndex, LangChain, AutoGen, and the rest of the RAG and agent stack, plus public demos searching everything from all of Wikipedia to a billion-document web corpus, and Semantic.art, which finds artworks by mood and description rather than by title or artist.
• Wrote much of the company's technical content, including LLMs, RAG, and the missing storage layer for AI and the practical guides on training rerankers and fine-tuning embedding models.
• Peer-reviewed research along the way, including stable-worldmodel with Yann LeCun and others. The rest is on my Scholar page.

• Co-authored the model families the framework is known for: YOLOv8, downloaded more than 20 million times in its first year, and the first instance-segmentation model to run in real time on a CPU.
• Co-authored the Ultralytics framework itself, which became the world's most popular open-source computer vision framework, with 60,000+ GitHub stars. Most of my 17,000+ academic citations come from the papers and software releases I co-authored there.
• Led the community and business development work that produced the company's first revenue from open source.

• Created the open-source integrations and partnerships channel and made W&B native inside the tools the ML world already used: Hugging Face Transformers, spaCy, YOLOv5, Catalyst, ESPnet, and more. It became the company's biggest source of new users.
• Wrote tutorials on scaling hyperparameter optimization and pipeline versioning, including for Towards Data Science.

Ayush Chaurasia builds AI products for developers and researchers and does independent research in multimodal learning and world models. He is the founding ML engineer at LanceDB, previously led the ML team at Ultralytics, and built and led the open-source integrations and partnerships channel at Weights & Biases. His co-authored papers and software releases have received more than 17,000 academic citations. He speaks about retrieval, multimodal systems, and building developer products.
