OpenAI’s outsourcing partner was Sama, a training-data company based in San Francisco, California. Users sometimes need to reword questions multiple times for ChatGPT to understand their intent. Upon launching the prototype, users were given a waitlist to sign up for. With a subscription to ChatGPT Plus, you can access GPT-4, GPT-4o mini or GPT-4o.

- It is designed to generate human-like text and can carry out a wide variety of tasks.
- ChatGPT became one of the fastest-growing apps in history, amassing hundreds of millions of users.
- In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks).
- ChatGPT faces ongoing legal challenges related to industry concerns regarding the ethics and the legality of data sourcing for AI training.

ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance.
Is there a ChatGPT app?
This tool allows a user to customize ChatGPT’s behavior for a specific use case. The Pro launch coincided with the release of the o1 model, providing unlimited access to o1 and advanced voice mode. In March 2025, OpenAI updated ChatGPT to generate images using GPT-4o instead of DALL-E. By January 2023, ChatGPT had Rolldorado become the fastest-growing consumer software application in history, gaining over 100 million users in two months.
Apps
GPT-4o is the most advanced version accessible to everyone, handling text, images and audio as input and output. ChatGPT is the artificial intelligence chatbot that started the whole generative AI revolution. In August 2024, the FTC voted unanimously to ban marketers from using fake user reviews created by generative AI chatbots (including ChatGPT) and influencers paying for bots to increase follower counts. In late March 2023, the Italian data protection authority banned ChatGPT in Italy and opened an investigation. OpenAI said it has taken steps to effectively clarify and address the issues raised; an age verification tool was implemented to ensure users are at least 13 years old.

Beyond text, ChatGPT can generate original images and videos through its integrated tools. If you prefer to keep using Dall-E 3 (its first image generator), you can still access it through the Dall-E GPT. That’s one reason why it sometimes “hallucinates” or generates confident-sounding but incorrect information.
- ChatGPT is a generative artificial intelligence chatbot developed by OpenAI and released in November 2022.

The company announced a slew of generative AI-powered features to counter OpenAI and Microsoft. A 2023 analysis estimated that ChatGPT hallucinates around 3% of the time. In July, OpenAI released ChatGPT agent, an AI agent that can perform multi-step tasks. The user can interrupt tasks or provide additional instructions as needed. In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks).
