ThirdAI Corp. is an artificial intelligence software company focused on making AI more scalable and sustainable by innovating how neural networks are trained and run. ThirdAI Corp. develops algorithmic solutions that allow large-scale AI models to be trained and deployed efficiently on commodity CPUs, rather than relying on specialized hardware like GPUs.
Their core innovation is a suite of hash-based processing algorithms, developed over a decade of research, that enables neural network training and inference to run dramatically faster—up to 15 times faster—on standard x86 CPUs compared to leading NVIDIA GPUs for specific workloads. This approach challenges the prevailing belief in the AI industry that GPUs are always superior for deep learning tasks.
ThirdAI’s technology aims to reduce the cost and infrastructure barriers typically associated with advanced AI workloads. The company’s advancements have received attention from major industry observers, with IEEE Spectrum describing their results as “stunning,” and media outlets like Engadget, Investorplace, and WCCFTech noting their potential to disrupt the deep learning ecosystem.
How was ThirdAI started?
ThirdAI Corp. was founded by a team with deep expertise in machine learning, engineering, and cloud infrastructure. The founding team includes Weiyi Sun (Director of Machine Learning at Wayfair), Will Ballard (Chief Engineer), and Tyler Jones (from AWS). Their combined experience has shaped ThirdAI’s focus on innovative AI acceleration and practical deployment at scale.
