Mathias Lechner

I am Co-founder and CTO of Liquid AI, a startup founded in 2023 to focus on building efficient foundation models at every scale. We raised a Series A led by AMD, Shopify, Samsung, and G42 at a valuation of $2.3B. We build and release state-of-the-art language models called LFM2 at 1B parameters and below that run efficiently on CPU and edge devices. LFM2 outperform similar sized models such as Llama3 and Qwen3 at both speed and performance.

I am also a Research Affiliate at the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT working with Prof. Daniela Rus. I completed my PhD (2022) at the Institute of Science and Technology Austria (ISTA) supervised by Tom Henzinger. Prior to my PhD, I received my master (2017) and bachelor (2016) degrees in Computer Science at the Vienna University of Technology (TU Wien).

Together with my colleague Djordje Zikelic I received the 2023 Outstanding Scientific Achievement Award at the Institute of Science and Technology Austria for our work on proving safety in stochastic machine learning systems. With my colleague Ramin Hasani, I got the Hyperion Research 2022 HPC Innovation Excellence Award for my work on Liquid neural and was honored as Outstanding Reviewer at ICRA 2021. I co-led the team that won the F1-Tenth - Autonomous Racing Grand Prix at IFAC 2020, and I received the Distinguished Young Alumni award at TU Vienna in 2018 for my MS thesis.
