ChatGPT is the AI assistant that introduced conversational AI to a mainstream global audience, and it continues to set the benchmark for breadth of capability. It combines a powerful language model with tools for browsing the web, running Python code, generating images with DALL-E, and analysing uploaded files — all within a single conversation. With hundreds of millions of users and a rich plugin and GPT ecosystem, ChatGPT remains the default starting point for anyone exploring AI assistants.
