Nabla is a digital health startup. It is the first disclosed partner of AMI Labs, a new venture co-founded by Yann LeCun focused on building world models. Nabla's CEO, Alexandre LeBrun, also serves as Chairman of Nabla and has identified limitations in large language models (LLMs) for healthcare applications, particularly concerning hallucinations which can have life-threatening consequences. Nabla is positioned to be an early adopter of AMI Labs' world model technology, which aims to understand the real world rather than just language.
