NovaSky, based at UC Berkeley, has unveiled Sky-T1-32B-Preview, an advanced reasoning AI model that can be trained for under $450. This open-source model competes with OpenAI's o1 on key benchmarks, showcasing the potential for affordable high-level reasoning capabilities. Unlike typical AI models, Sky-T1 fact-checks its own outputs, enhancing reliability in fields like science and mathematics. While it excels in various math challenges, it still faces limitations in complex physics questions. The team aims to further enhance model efficiency and accuracy in upcoming developments.
