ChatGPT is OpenAI's conversational AI assistant, launched publicly on November 30, 2022. OpenAI itself was founded in 2015 by Sam Altman, Greg Brockman, Ilya Sutskever, and others, and is headquartered in San Francisco, California, with roughly 8,000 employees as of 2026.
ChatGPT is used for writing, coding, research, data analysis, and conversation, and is available on the web, iOS and Android apps, macOS and Windows desktop apps, and via a developer API. As of mid-2026 it runs on OpenAI's GPT-5 model family, which spans multiple capability tiers routed by plan and task complexity.
Core capabilities include Custom GPTs (configurable assistants with their own instructions and knowledge), Projects for organizing related work, persistent memory across conversations, real-time web browsing with citations, sandboxed code execution, image generation, and Voice Mode for spoken conversation.
Developers can build on ChatGPT's underlying models through OpenAI's API, and organizations can deploy ChatGPT with admin controls, SSO, and data-training exclusions through the Business and Enterprise tiers.
ChatGPT offers a Free plan, a lower-cost Go plan (~$8/month), Plus ($20/month), and Pro ($200/month) for individuals, plus Business (~$25-30/user/month) and custom-priced Enterprise plans for organizations. Higher tiers add usage headroom, advanced model access, and administrative/security controls rather than a fundamentally different product.
