One of the most significant improvements was in the generation of text within images, which is especially useful for branded content. In March 2025, OpenAI updated ChatGPT to generate images using GPT Image instead of DALL-E. In October 2023, OpenAI’s image generation model DALL-E 3 was integrated into ChatGPT.

The chatbot can assist patients seeking clarification about their health. The uses and potential of ChatGPT in health care has been the topic of scientific publications and experts have shared many opinions. Many companies adopted ChatGPT and similar chatbot technologies into their product offers. The Guardian questioned whether any content found on the Internet after ChatGPT’s release “can be truly trusted” and called for government regulation. In June 2023, hundreds of people attended a “ChatGPT-powered church service” at St. Paul’s Church in Fürth, Germany.
This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT. 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. ChatGPT has never been publicly available in China because OpenAI prevented Chinese users from accessing their site. Kevin Roose of The New York Times called it “the best artificial intelligence chatbot ever released to the general public”.
At launch, the feature was limited to purchases on Etsy from US users with a payment method linked to their OpenAI account. The user can interrupt tasks or provide additional instructions as needed. In July 2025, OpenAI released ChatGPT agent, an AI agent that can perform multi-step tasks. It was capable of autonomously performing tasks through web browser interactions, including filling forms, placing online orders, scheduling appointments, and other browser-based tasks. The integration used ChatGPT to write prompts for DALL-E guided by conversations with users. At launch, OpenAI included more than 3 million GPTs created by GPT Builder users in the GPT Store.

Version History

ChatGPT is programmed to reject prompts that may violate its content policy. In one instance, ChatGPT generated a rap in which women and scientists of color were asserted to be inferior to white male scientists. The reward model of ChatGPT, designed around human oversight, can be over-optimized and thus hinder performance, in an example of an optimization pathology known as Goodhart’s law. OpenAI has sometimes mitigated this effect by updating the training data. The feature is not available for users in the UK, Switzerland, or the European Economic Area, and is available on a waitlist basis everywhere else.

Perplexity – AI Search & Chat

In November 2023, OpenAI released GPT Builder a tool for users to customize ChatGPT’s behavior for a specific use case. GPT-based moderation classifiers are used to reduce the risk of harmful outputs being presented to users. ChatGPT is frequently used for translation and summarization tasks, and can simulate interactive environments such as a Linux terminal, a multi-user chat room, or simple text-based games such as tic-tac-toe. It is designed to generate human-like text and can carry out a wide variety of tasks.
Their leaders emphasized their earlier caution regarding public deployment was due to the trust the public places in Google Search. Kelsey Piper of Vox wrote that “ChatGPT is the general public’s first hands-on introduction to how powerful modern AI has gotten” and that ChatGPT is “smart enough to be useful despite its flaws”. As before, OpenAI has not disclosed technical details such as the exact number of parameters or the composition of its training dataset.

O1 is designed to solve more complex problems by spending more time “thinking” before it answers, enabling it to analyze its answers and explore different strategies. In September 2024, OpenAI introduced o1-preview and a faster, cheaper model named o1-mini. On July 18, 2024, OpenAI released GPT-4o mini, a smaller version of GPT-4o which replaced https://www.luckytwicecasino.eu/ GPT-3.5 Turbo on the ChatGPT interface. OpenAI has not revealed technical details and statistics about GPT-4, such as the precise size of the model. The term “hallucination” as applied to LLMs is distinct from its meaning in psychology, and the phenomenon in chatbots is more similar to confabulation or bullshitting. A 2023 analysis estimated that ChatGPT hallucinates around 3% of the time.
ChatGPT is a generative artificial intelligence chatbot developed by OpenAI. TechRadar is part of Future US Inc, an international media group and leading digital publisher. Now, he’s continuing to tell the stories people want and need to hear about the rapidly evolving AI space and its impact on their lives.
In September 2025, OpenAI added a feature called Pulse, which generates a daily analysis of a user’s chats and connected apps such as Gmail and Google Calendar. In December 2024, OpenAI launched a new feature allowing users to call ChatGPT with a telephone for up to 15 minutes per month for free. An optional “Memory” feature allows users to tell ChatGPT to memorize specific information. ChatGPT’s training data includes software manual pages, information about internet phenomena such as bulletin board systems, multiple programming languages, and the text of Wikipedia.
Shortly after the bug was fixed, users could not see their conversation history. In March 2023, a bug allowed some users to see the titles of other users’ conversations. Despite this, users may jailbreak ChatGPT with prompt engineering techniques to bypass these restrictions.

• Between March and April 2023, Il Foglio published one ChatGPT-generated article a day on its website, hosting a special contest for its readers in the process.
• In medical education, it can explain concepts, generate case scenarios, and be used by students preparing for licensing examinations.
• Juergen Schmidhuber said that in 95% of cases, AI research is about making “human lives longer and healthier and easier.” He added that while AI can be used by bad actors, it “can also be used against the bad actors”.

It can generate plausible-sounding but incorrect or nonsensical answers, known as hallucinations. The chatbot has also been criticized for its limitations and potential for unethical use. It has been lauded for its potential to transform numerous professional fields, and instigated public debate about the nature of creativity and the future of knowledge work. It is credited with accelerating the AI boom, an ongoing period marked by rapid investment and public attention toward the field of artificial intelligence (AI). Privacy practices may vary, for example, based on the features you use or your age.

In The Atlantic magazine’s “Breakthroughs of the Year” for 2022, Derek Thompson included ChatGPT as part of “the generative-AI eruption” that “may change our mind about how we work, how we think, and what human creativity is”. Samantha Lock of The Guardian noted that it was able to generate “impressively detailed” and “human-like” text. GPT-4o’s ability to generate images was released later, in March 2025, when it replaced DALL-E 3 in ChatGPT. GPT-4o (“o” for “omni”) is a multilingual, multimodal generative pre-trained transformer developed by OpenAI and released in May 2024. As of 2026update, if the user turns off data sharing for privacy, all previous transcripts and projects are permanently deleted without warning.

GPT-4.5

Chris Granatino, a librarian at Seattle University, noted that while ChatGPT can generate content that seemingly includes legitimate citations, in most cases those citations are not real or largely incorrect. Robin Bauwens, an assistant professor at Tilburg University, found that a ChatGPT-generated peer review report on his article mentioned nonexistent studies. 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”. Over 20,000 signatories including Yoshua Bengio, Elon Musk, and Apple co-founder Steve Wozniak, signed a March 2023 open letter calling for an immediate pause of giant AI experiments like ChatGPT, citing “profound risks to society and humanity”. In July 2023, the FTC launched an investigation into OpenAI over allegations that the company scraped public data and published false and defamatory information.
According to TechCrunch, it is a service based on o3 that combines advanced reasoning and web search capabilities to make comprehensive reports within 5 to 30 minutes. ChatGPT’s Mandarin Chinese abilities were lauded, but the ability of the AI to produce content in Mandarin Chinese in a Taiwanese accent was found to be “less than ideal” due to differences between mainland Mandarin Chinese and Taiwanese Mandarin. However, no machine translation services match human expert performance.
