ChatGPT

ChatGPT is OpenAI's conversational AI assistant, built on the GPT family of large language models, capable of answering questions, writing and debugging code, drafting content, and reasoning through multi-step problems in natural conversation. Custom GPTs let users and businesses build tailored versions of ChatGPT with specific instructions, knowledge files, and connected tools, effectively turning the base model into purpose-built assistants without any coding. Advanced Voice Mode enables natural, low-latency spoken conversations. ChatGPT Enterprise adds unlimited higher-context usage, advanced data analysis, and enterprise-grade security and admin controls, while the underlying API powers a huge portion of third-party AI products across the industry.
