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 Rolldorado the issues raised; an age verification tool was implemented to ensure users are at least 13 years old.

Is ChatGPT better than a search engine?

• The tool can be called on manually or activated whenever a user prompt could benefit from web-based information.

{

• Despite this, users may “jailbreak” ChatGPT with prompt engineering techniques to bypass these restrictions.

• With a subscription to ChatGPT Plus, you can access GPT-4, GPT-4o mini or GPT-4o.

{

• GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users.

• The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code.

{

• Many individuals use ChatGPT and comparable large language models (LLM) for mental health and emotional support.

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.

Choose your AI model

In May 2024, however, OpenAI supercharged the free version of its chatbot with GPT-4o. After the upgrade, ChatGPT reclaimed its crown as the best AI chatbot. Despite this, users may “jailbreak” ChatGPT with prompt engineering techniques to bypass these restrictions. ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance.

• OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations.

{

• GPT-4o is OpenAI’s latest, fastest, and most advanced flagship model.

• Originally based on OpenAI’s GPT-3 architecture, ChatGPT has evolved.
• OpenAI has sometimes mitigated this effect by updating the training data.

{

• The integration used ChatGPT to write prompts for DALL-E guided by conversations with users.

• It currently uses GPT-5, a generative pre-trained transformer (GPT), to generate text, speech, and images in response to user prompts.

What are the best ChatGPT alternatives?

Many companies adopted ChatGPT and similar chatbot technologies into their product offers. Spanish chemist Rafael Luque published a plethora of research papers in 2023 that he later admitted were written by ChatGPT. ChatGPT also provided an outline of how human reviewers are trained to reduce inappropriate content and to attempt to provide political information without affiliating with any political position.

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 become the fastest-growing consumer software application in history, gaining over 100 million users in two months.

What is Microsoft’s involvement with ChatGPT?

Released in February 2025, GPT-4.5 was described by Altman as a “giant, expensive model”. It is capable of writing software, answering codebase questions, running tests, and proposing pull requests. The languages tested were Polish, French, Korean, Spanish, Arabic, Tagalog, and Amharic. For more common languages, AI translators like ChatGPT did better than Google Translate, while for “niche” languages (Amharic and Tagalog), Google Translate performed better. None of the tested services were a perfect replacement for a fluent human translator.

It was trained on massive amounts of data from books and the internet — websites, Wikipedia, Reddit threads, news sites and much, much more. Some, including Nature and JAMA Network, “require that authors disclose the use of text-generating tools and ban listing a large language model (LLM) such as ChatGPT as a co-author”. As of July 2025, Science expects authors to release in full how AI-generated content is used and made in their work.

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.
In March 2023, a bug allowed some users to see the titles of other users’ conversations. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations. Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs. They can explicitly tell ChatGPT to remember aspects of the conversation, and ChatGPT can use these details in future conversations. OpenAI collects data from ChatGPT users to further train and fine-tune its services. The laborers were exposed to toxic and traumatic content; one worker described the assignment as “torture”.
