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.

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).

- OpenAI’s outsourcing partner was Sama, a training-data company based in San Francisco, California.
- ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events.
- For example, you can teach an agent to gather background research on new leads and keep you up to date.
- GPT-4 is OpenAI’s language model, much more advanced than its predecessor, GPT-3.5.
- As of 2025, ChatGPT’s website is among the 5 most-visited websites globally, and has over 800 million active weekly users.
- Over a month after the announcement, Google began rolling out access to Bard first via a waitlist.

How to delete your ChatGPT conversations from a desktop
- ChatGPT faces ongoing legal challenges related to industry concerns regarding the ethics and the legality of data sourcing for AI training.
- They can explicitly tell ChatGPT to remember aspects of the conversation, and ChatGPT can use these details in future conversations.
- It is designed to generate human-like text and can carry out a wide variety of tasks.
- Spanish chemist Rafael Luque published a plethora of research papers in 2023 that he later admitted were written by ChatGPT.
- For more common languages, AI translators like ChatGPT did better than Google Translate, while for “niche” languages (Amharic and Tagalog), Google Translate performed better.
- ChatGPT became one of the fastest-growing apps in history, amassing hundreds of millions of users.

The fine-tuning process involved supervised learning and reinforcement learning from human feedback (RLHF). In the case of supervised learning, the trainers acted as both the user and the AI assistant. In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations. OpenAI will, by default, use your conversations with the free chatbot to train data and refine its models. Recently, OpenAI made ChatGPT’s image generation capabilities free for all users, albeit with a limited number of monthly uses.
GPT-4.5
As of 2025, ChatGPT’s website is among the 5 most-visited websites globally, and has over 800 million active weekly users. We process your data to deliver content or advertisements and measure the delivery of such content or advertisements to extract insights about our website. With the user’s permission, Siri can request ChatGPT for help if Siri deems a task is better suited for ChatGPT.

- OpenAI once offered plugins for ChatGPT to connect to third-party applications and access real-time information on the web.
- Stanford researchers reported that GPT-4 “passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative.”
- ChatGPT relies on large language models (LLMs), enabling it to understand your questions and provide human-like responses.
- Users sometimes need to reword questions multiple times for ChatGPT to understand their intent.
- This means you can spend less time crafting a tailored search query but still get exactly what you want.
- In March 2025, OpenAI updated ChatGPT to generate images using GPT-4o instead of DALL-E.

ChatGPT
ChatGPT runs on a large language model (LLM) architecture created by OpenAI called the Generative Pre-trained Transformer (GPT). Now, the free version Rolldorado runs on GPT-4o mini, with limited access to GPT-4o. Microsoft’s Copilot offers free image generation, also powered by DALL-E 3, in its chatbot. These fears even led some school districts to block access when ChatGPT initially launched. As of this writing, ChatGPT’s main models are GPT-5, GPT-5 mini, and GPT-5 nano.
