AI startup Recursive on Wednesday (October 20) released Flint, a free programming model that runs on laptops. The company stated that the model was primarily built by its internal AI research system and is designed to initially test AI's self-improvement capabilities. Recursive's automated research system, "Eureka Machine," assisted in almost every step of Flint's development process, enabling a small team to build the model from scratch in less than four months. Flint is a Mixture-of-Experts (MoE) model with 40 billion parameters, but only 2.5 billion are used per task, making it lightweight enough to run on a standard laptop. The company was founded last year and secured $650 million in funding at a $4.65 billion valuation in May this year, with investors including GV, NVIDIA, and AMD Ventures.
