Nabla and Advanced Machine Intelligence, a new AI research company founded by deep learning pioneer Professor Yann LeCun, announced an exclusive strategic partnership on December 18, 2025. This partnership gives Nabla first access to new global model technology and positions the company to pioneer FDA-cleared agent AI systems for clinical care. Building on LeCun's early investment and confidence in Nabla's technology vision, this partnership aims to advance healthcare AI beyond current large-scale language models by enabling deterministic decision-making, simulation-based inference, and robust processing of continuous medical signals.
Nabla and Advanced Machine Intelligence partnership
On December 18, 2025, Nabla announced an exclusive strategic partnership with Advanced Machine Intelligence, a new AI research company founded by Professor Yann LeCun. This partnership gives Nabla first access to new global modeling technology and positions the company to pioneer FDA-cleared agent AI systems in the medical field. LeCun, a deep learning pioneer and early investor in Nabla, believes Nabla's focus on safety and real-world deployment makes it an ideal partner for this innovation.
World models are considered the next big architectural change in healthcare AI that addresses the limitations of current large-scale language models (LLMs). These models enable deterministic and auditable decision-making, simulation-based inference, and robust processing of continuous medical signals such as voice and vitals. Nabla aims to combine world models and LLM to build the foundation for safe and practical clinical AI, moving beyond documentation support to autonomous systems.
As part of the planned transition, Nabla co-founder and CEO Alex LeBrun will become CEO of Advanced Machine Intelligence, while also serving as Nabla's lead AI scientist and chairman. Delphine Groll, Nabla's co-founder and COO, will continue to lead day-to-day operations. Nabla has raised $120 million from investors including Yann LeCun and Tony Fadell and currently integrates with all major electronic health records (EHRs).
Advances in healthcare AI through global models
Nabla has partnered with Advanced Machine Intelligence, founded by deep learning pioneer Professor Yann LeCun, to advance healthcare AI through “world model” technology. This collaboration aims to build on current large-scale language model (LLM) systems by addressing limitations such as hallucinations and processing continuous medical data. Nabla will have first access to these emerging technologies, allowing us to build FDA-cleared agent AI systems for healthcare focused on reliability and deterministic reasoning.
The world model represents a significant architectural change that allows healthcare AI to go beyond the limitations of LLM. These models facilitate deterministic and auditable decision-making, simulation-based reasoning (“what-if” analysis), and robust processing of continuous medical signals such as voice, vitals, and images. The combination of world models and LLM is considered the basis for safe and practical clinical AI, ultimately supporting more autonomous and reliable systems within medical workflows.
As part of the planned transition, Nabla co-founder and CEO Alex LeBrun will remain Nabla's chairman and chief AI scientist and become CEO of Advanced Machine Intelligence. This move will strengthen Nabla's long-term technology vision. The company plans to expand its ambient AI assistant and invest in multimodality, simulation, and deterministic inference to build the next generation of agent systems, continuing to prioritize safety, ease of use, and real-world deployment.
Healthcare AI is entering a new era where reliability, determinism, and simulation are as important as linguistic intelligence.

Nabla Products, Integrations, and Company Overview
Nabla provides an AI assistant designed to optimize clinical and financial workflows, with a focus on restoring relationships in healthcare. Its core products include web apps, iOS and Android apps, Chrome extensions, and APIs for integration. Today, Nabla integrates with all major EHRs, including Epic and athenahealth, supports over 35 languages, and serves over 150 health systems and provider groups. The company is evolving toward an adaptive agent platform that extends its capabilities beyond documentation.
Nabla recently announced an exclusive partnership with Advanced Machine Intelligence, founded by Yann LeCun, to pioneer agent AI systems in healthcare. This collaboration will give Nabla first access to emerging world model technology and aims to overcome the limitations of current LLM-based systems. These world models enable the deterministic inference, simulation-based analysis, and robust processing of continuous medical signals that are essential for safe and autonomous clinical AI.
Founded by Alex LeBrun, Delphine Groll, and Martin Raison, Nabla has raised $120 million in funding from investors including Yann LeCun and Tony Fadell. The planned leadership changes will see Alex LeBlanc become CEO of Advanced Machine Intelligence and Chief AI Scientist and Chairman of Nabla, while Delphine Grohl will continue to lead day-to-day operations. This will lead Nabla to further invest in multimodality, simulation, and deterministic inference.
