In the UK, a judge expressed concern about self-representing litigants wasting time by submitting documents containing significant hallucinations. In November 2025, OpenAI acknowledged that there have been “instances where our 4o model fell short in recognizing signs of delusion or emotional dependency”, and reported that it is working to improve safety. In medical education, it can explain concepts, generate case scenarios, and be used by students preparing for licensing examinations. 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.
For the last five years, he served as head writer for Voicebot.ai and was on the leading edge of reporting on generative AI and large language models. Despite decades of using AI, Wall Street professionals report that consistently beating the market with AI, including recent large language models, is challenging due to limited and noisy financial data. In January 2023, the International Conference on Machine Learning banned any undocumented use of ChatGPT or other large language models to generate any text in submitted papers.

OpenAI under fire: Can chatbots ever truly be child-safe?

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. Italian regulators assert that ChatGPT was exposing minors to age-inappropriate content, and that OpenAI’s use of ChatGPT conversations as training data could violate Europe’s General Data Protection Regulation. A shadow market has emerged for Chinese users to get access to foreign software tools. 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. In December 2023, ChatGPT became the first non-human to be included in Nature’s 10, an annual listicle curated by Nature of people considered to have made significant impact in science. ChatGPT gained one million users in five days and 100 million in two months, becoming the fastest-growing internet application in history.
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.

Perplexity – AI Search & Chat

• 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.
• Geoffrey Hinton, one of the “fathers of AI”, voiced concerns that future AI systems may surpass human intelligence.
• In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations.
• 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.
• In October 2023, OpenAI’s image generation model DALL-E 3 was integrated into ChatGPT.
• One of the most significant improvements was in the generation of text within images, which is especially useful for branded content.

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. In September 2025, following the suicide of a 16-year-old, OpenAI said it planned to add restrictions for users under 18, including the blocking of graphic sexual content and the prevention of flirtatious talk. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations. These images are generated with C2PA metadata, which can be used to verify that they are AI-generated. The model can also generate new images based on existing ones provided in the prompt.

ChatGPT Health

His experience runs the gamut of https://www.luckytwicecasino.eu/ media, including print, digital, broadcast, and live events. But when you flip the right switch, the model starts to surprise you. Most people don’t explore that space.
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.

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.

GPT-4.5

These limitations may be revealed when ChatGPT responds to prompts including descriptors of people. ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events. To implement the feature, OpenAI partnered with data connectivity infrastructure company b.well. On January 7, 2026, OpenAI introduced a feature called “ChatGPT Health”, whereby ChatGPT can discuss the user’s health in a way that is separate from other chats. In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks).

The model’s baseline tone is practical, but a perspective shift convinces it to behave like a storyteller instead of a rulebook. If you ask directly, the model will give you competent, but not very inspiring, buying advice. I want a hot take that sounds like it would start a family argument.” The trick here is to acknowledge what the model typically gives you and frame the request as a deviation. ” The tasks are still useful, but the tone shifts from bland to bracing.
It has an additional feature called “agentic mode” that allows it to take online actions for the user. The laborers were exposed to toxic and traumatic content; one worker described the assignment as “torture”. To build a safety system against harmful content (e.g., sexual abuse, violence, racism, sexism), OpenAI used outsourced Kenyan workers, earning around $1.32 to $2 per hour, to label such content. In the case of supervised learning, the trainers acted as both the user and the AI assistant. The fine-tuning process involved supervised learning and reinforcement learning from human feedback (RLHF).

• 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.
• Another study, focused on the performance of GPT-3.5 and GPT-4 between March and June 2024, found that performance on objective tasks like identifying prime numbers and generating executable code was highly variable.
• Most people don’t explore that space.
• ChatGPT gained one million users in five days and 100 million in two months, becoming the fastest-growing internet application in history.
• 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”.

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.
In response, many educators are now exploring ways to thoughtfully integrate generative AI into assessments. Efforts to ban chatbots like ChatGPT in schools focus on preventing cheating, but enforcement faces challenges due to AI detection inaccuracies and widespread accessibility of chatbot technology. The potential benefits include enhancing personalized learning, improving student productivity, assisting with brainstorming, summarization, and supporting language literacy skills. The chatbot technology can improve security by cyber defense automation, threat intelligence, attack identification, and reporting. In an industry survey, cybersecurity professionals argued that it was attributable to cybercriminals’ increased use of generative artificial intelligence (including ChatGPT). Another study, focused on the performance of GPT-3.5 and GPT-4 between March and June 2024, found that performance on objective tasks like identifying prime numbers and generating executable code was highly variable.
