What is GPT Astar? Meet the AI assistant with 7 specialist models
GPT Astar TeamGPT Astar is an AI assistant for writing, coding, study, translation and long documents. Meet the GPT Astar model family, see which model fits which job, and what it costs.
GPT Astar is an AI assistant for everyday work and study. Instead of one general model for everything, it gives you a family of seven models, each built for a job — writing, coding, translation, deep reasoning and long documents — in a single chat. You can use it free every day (20 messages), and Pro costs $9.90 a month, about half of a typical $20 AI subscription.
