Artificial intelligence continues to rapidly evolve, and a new player has officially entered the field. Renowned AI scientist Yann LeCun has confirmed the launch of his startup, Advanced Machine Intelligence (AMI), focused on developing world model AI. The company, however, will be led by a new CEO, signaling a different approach to leadership than some other high-profile AI ventures.
The announcement, made Thursday, confirmed long-standing rumors within the tech industry. LeCun, formerly VP and Chief AI Scientist at Meta, will serve as Executive Chairman of AMI, while Alex LeBrun, previously CEO of medical transcription AI company Nabla, will take the helm as CEO. LeBrun’s transition was announced by Nabla in a press release, with LeCun subsequently confirming the news on LinkedIn.
AMI Labs Seeks Significant Funding for World Model AI Development
AMI Labs is reportedly aiming to raise a substantial €500 million (approximately $586 million) at a valuation of €3 billion (around $3.5 billion). This ambitious fundraising goal comes even before the company has launched its first product. However, given the current investment climate for AI startups, particularly those founded by leading researchers, this ask isn’t entirely unexpected.
Recent examples demonstrate the high valuations being placed on AI companies. Thinking Machines Lab, founded by former OpenAI CTO Mira Murati, secured a $12 billion valuation in its seed round last year. Notably, LeCun’s established reputation in the field arguably surpasses that of Murati, potentially justifying AMI’s valuation expectations.
The Promise of World Models
AMI Labs’ core focus is on world model AI, a distinct approach from the currently dominant Large Language Models (LLMs). World models aim to create AI systems that understand and simulate the environment around them, enabling them to predict outcomes and reason about cause and effect. This is seen by many as a potential solution to the “hallucination” problem inherent in LLMs, where the models generate factually incorrect or nonsensical information.
Several leading AI labs are also pursuing world model technology, including Google DeepMind and Fei-Fei Li’s World Labs. World Labs, for instance, raised $230 million at a $1 billion valuation in August 2024, a figure that now seems relatively modest considering the rapid pace of innovation in the artificial intelligence space.
The development of robust world models is considered a key step towards achieving Artificial General Intelligence (AGI), a hypothetical level of AI that possesses human-like cognitive abilities. This pursuit is driving significant investment and research across the industry.
Nabla’s Future and the Leadership Transition
Meanwhile, Nabla is navigating its own leadership change. The company will be temporarily led by co-founder and COO Delphine Groll while it searches for a permanent CEO. Despite LeBrun’s departure, Nabla reports strong growth, with live Annual Recurring Revenue (ARR) having tripled this year and aiming to reach $1 billion.
Nabla has also secured a partnership to integrate AMI’s models as they become available, suggesting a continued collaborative relationship between the two companies. Nabla has attracted substantial investment, raising $120 million in total from investors including Tony Fadell’s Build Collective and HV Capital.
LeBrun brings a wealth of experience to AMI, having previously worked on multimodal AI at Nuance Communications (later acquired by Microsoft) and led AI divisions at Facebook. His background in building and scaling AI-powered products positions him well to lead AMI’s development and commercialization efforts. He will remain Chairman and Chief AI Scientist at Nabla.
The rise of machine learning startups like AMI and Nabla highlights the increasing commercialization of AI research. These companies are attempting to translate cutting-edge academic work into practical applications with significant market potential.
Looking ahead, the success of AMI Labs will depend on its ability to develop and deploy effective world models, secure the necessary funding, and navigate the competitive landscape of the AI industry. The next few months will be crucial as the company builds its team and begins to demonstrate its technological capabilities. Investors will be closely watching to see if AMI can deliver on its ambitious promises and establish itself as a leader in the next generation of AI.
