Advanced Machine Intelligence Labs (AMI Labs) is a Paris-based AI startup co-founded by Turing Award winner Yann LeCun after his departure from Meta. Announced on March 9, 2026, AMI Labs raised $1.03 billion in seed funding at a $3.5 billion pre-money valuation — Europe's largest seed round on record. The company is building world models based on LeCun's Joint Embedding Predictive Architecture (JEPA), targeting industrial, robotic, and healthcare applications where the limitations of large language models are most consequential. 1)
LeCun co-founded AMI Labs with Alexandre LeBrun, who previously founded Wit.ai (acquired by Facebook in 2015) and later served as CEO of Nabla, a digital health startup. Both founders reached the same conclusion: LLMs hallucinate, and that hallucination problem represents a hard ceiling — especially in safety-critical domains like healthcare. 2)
The research team includes:
AMI Labs' first partner is Nabla, LeBrun's digital health company, signaling healthcare as an early application domain.
LeCun has long argued that the current path of large language models — relying on next-token prediction — is a dead end for achieving human-level AI. While LLMs excel at mimicking language patterns, they lack fundamental understanding of the physical world. 3)
World models, by contrast, learn internal representations of how the physical world works:
This approach aims to produce AI that can plan, reason about consequences, and interact with the real world — capabilities that text-based models fundamentally lack.
AMI Labs' technical foundation is the Joint Embedding Predictive Architecture (JEPA), a self-supervised learning framework developed by LeCun and his team at Meta AI:
On March 24, 2026, LeCun's team published LeWorldModel (LeWM), the first end-to-end JEPA system trained from raw pixels that successfully solves the collapse problem in world models. 4) 5) This represents a significant technical milestone, as previous attempts at building world models from pixels suffered from representation collapse.
| Aspect | Large Language Models | World Models (JEPA) |
| Training data | Text tokens | Visual/physical data, video, sensor input |
| Prediction target | Next token | Abstract representations of future states |
| World understanding | Statistical patterns in language | Physical causality and spatial reasoning |
| Hallucination | Inherent to architecture | Mitigated by grounding in physical reality |
| Applications | Text generation, coding, chat | Robotics, healthcare, autonomous systems |
The $1.03 billion seed round was co-led by:
Additional participation from NVIDIA and numerous venture firms. 6)
LeCun has been a vocal critic of the LLM paradigm, arguing:
AMI Labs is his attempt to prove this thesis by building an alternative path to advanced AI. CEO LeBrun has been explicit that AMI Labs is fundamental research with no near-term product or revenue — potentially a 5-10 year endeavor. 7)
LeBrun has also predicted: “My prediction is that 'world models' will be the next buzzword. In six months, every company will call itself a world model to raise funding.” 8)
