Overview
ChatGPT is OpenAI's general-purpose AI assistant in the ai-assistants category, used for writing, coding, analysis and everyday questions. It is run by OpenAI, a US company founded in 2015, and is currently powered by the GPT-6 Astra model family. You reach it on the web, in mobile and desktop apps, and through an API. The checkable recent change is model lineage: in September 2026 OpenAI introduced GPT-6 Astra as the current flagship family for ChatGPT and the API. Its recorded limitation is price transparency: the pricing page renders its plan prices in JavaScript and returned no figure in this review, so no plan price is recorded here.
