In August 2024, OpenAI announced it had created a text watermarking method but did not release it for public use, saying that users would go to a competitor without watermarking if it publicly released its watermarking tool. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations. … It’s also a way to understand the “hallucinations”, or nonsensical answers to factual questions, to which large language models such as ChatGPT are all too prone. 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. In October 2025, OpenAI reported that approximately 0.15% of ChatGPT’s active users in a given week have conversations including explicit indicators of potential suicidal planning or intent, translating to more than a million people weekly. ChatGPT is a chatbot and AI assistant built on large language model (LLM) technology.

Premium users were originally limited in the number of messages they could send to the new model, but OpenAI increased and eventually removed these limits. The model can also generate new images based on existing ones provided in the prompt, which can, for example, be used to transform images with specific styles or inpaint areas. In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations. ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance.
At launch, OpenAI included more than 3 million GPTs created by GPT Builder users in the GPT Store. The integration used ChatGPT to write prompts for DALL-E guided by conversations with users. In October 2023, OpenAI’s image generation model DALL-E 3 was integrated into ChatGPT Plus and ChatGPT Enterprise. GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users. 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.

Released in February 2025, GPT-4.5 was described by Altman as a “giant, expensive model”. In September 2024, OpenAI introduced o1-preview and a faster, cheaper model named o1-mini. Later reports showed the bug was much more severe than initially believed, with OpenAI reporting that fuckingshitmotherfucker it had leaked users’ “first and last name, email address, payment address, the last four digits (only) of a credit card number, and credit card expiration date”. 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.
Polishing the Experience GPT-5.1 (Nov : Personality, Style & Real-World Use
This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT. Geoffrey Hinton, one of the “fathers of AI”, voiced concerns that future AI systems may surpass human intelligence. The FTC asked OpenAI for comprehensive information about its technology and privacy safeguards, as well as any steps taken to prevent the recurrence of situations in which its chatbot generated false and derogatory content about people. A shadow market has emerged for users to get access to foreign software tools. Kevin Roose of The New York Times called it “the best artificial intelligence chatbot ever released to the general public”. Generative Pre-trained Transformer 4 (GPT-4) is a large language model developed by OpenAI and the fourth in its series of GPT foundation models.
The dangers are that “meaningless content and writing thereby becomes part of our culture, particularly on social media, which we nonetheless try to understand or fit into our existing cultural horizon.” This has led to concern over the rise of what has come to be called “synthetic media” and “AI slop” which are generated by AI and rapidly spread over social media and the internet. The Guardian questioned whether any content found on the Internet after ChatGPT’s release “can be truly trusted” and called for government regulation.

This will alert our moderators to take action In July 2024, the American Bar Association (ABA) issued its first formal ethics opinion on attorneys using generative AI.
On November 29, Rosário revealed that the bill had been entirely written by ChatGPT, and that he had presented it to the rest of the council without making any changes or disclosing the chatbot’s involvement. The attorneys were sanctioned for filing the motion and presenting the fictitious legal decisions ChatGPT generated as authentic. In Mata v. Avianca, Inc., a personal injury lawsuit filed in May 2023, the plaintiff’s attorneys used ChatGPT to generate a legal motion.

ChatGPT shows inconsistent responses, lack of specificity, lack of control over patient data, and a limited ability to take additional context (such as regional variations) into consideration. 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.
As before, OpenAI has not disclosed technical details such as the exact number of parameters or the composition of its training dataset. According to OpenAI, it features reduced hallucinations and enhanced pattern recognition, creativity, and user interaction. GPT-4o (“o” for “omni”) is a multilingual, multimodal generative pre-trained transformer developed by OpenAI and released in May 2024. A study presented example attacks on ChatGPT, including jailbreaks and reverse psychology. ChatGPT is programmed to reject prompts that may violate its content policy.
GPT-4.5
That transforms your voice chats into a sort of hybrid mode that blends voice, text and informative widgets to give you the information you need at a glance. The ChatGPT-generated avatar told the people, “Dear friends, it is an honor for me to stand here and preach to you as the first artificial intelligence at this year’s convention of Protestants in Germany”. The chatbot technology can improve security by cyber defense automation, threat intelligence, attack identification, and reporting. In July 2024, Futurism reported that GPT-4o in ChatGPT would sometimes link “scam news sites that deluge the user with fake software updates and virus warnings”; these pop-ups can be used to coerce users into downloading malware or potentially unwanted programs. 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.
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. ChatGPT gained one million users in five days and 100 million in two months, becoming the fastest-growing internet application in history. 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”. 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-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API.
None of the tested services were a perfect replacement for a fluent human translator. In December 2023, the Albanian government decided to use ChatGPT for the rapid translation of European Union documents and the analysis of required changes needed for Albania’s accession to the EU. ChatGPT (based on GPT-4) was better able to translate Japanese to English when compared to Bing, Bard, and DeepL Translator in 2023. TrendForce market intelligence estimated that 30,000 Nvidia GPUs (each costing approximately $10,000–15,000) were used to power ChatGPT in 2023. According to the company, the paid version of the website was still experimental, but provided access during peak periods, no downtime, priority access to new features, and faster response speeds. ChatGPT was initially free to the public, and OpenAI planned to monetize the service later.
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. This tool allows a user to customize ChatGPT’s behavior for a specific use case.
