About ChatGPT
ChatGPT is the most widely used AI assistant in the world, built on OpenAI’s GPT-4o and o-series model family. Launched in late 2022, it sparked the modern wave of consumer AI and has since evolved into a full-featured platform handling everything from quick factual questions to multi-step reasoning, file analysis, image understanding, and production-quality code generation.
The free plan covers everyday use with access to GPT-4o mini, while ChatGPT Plus ($20/month) unlocks the strongest models, higher usage limits, and tools like Advanced Data Analysis, image generation via DALL·E, and real-time web browsing with cited sources. For teams, the Business and Enterprise plans add shared workspaces, admin controls, SSO, and data privacy guarantees.
What sets ChatGPT apart is its ecosystem: thousands of custom GPTs in the GPT Store let you find or build task-specific assistants without writing any code, while memory lets the model remember your preferences across sessions. The Canvas feature makes it a collaborative writing and coding partner — you can iterate on documents and code side-by-side.
ChatGPT is also available on iOS and Android with voice mode, letting you have real conversations using natural speech. For developers, the underlying OpenAI API powers integrations across every major platf
