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. As technology progresses, ChatGPT stands poised to automate various tasks traditionally handled by humans, spanning data entry, customer service, and translation assistance. OpenAI intends to introduce watermarks for longer text pieces to aid in identifying AI-generated content. To combat cheating and plagiarism, OpenAI introduced an AI text classifier aimed at distinguishing between human and AI-generated text. While there are no constraints on the types of questions users can ask, it’s essential to note that ChatGPT’s knowledge is limited to data available up to the year 2021.

How can you access ChatGPT?

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. 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. 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.

Additionally, users can access its privacy policy before registration. 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.

This makes it ideal for processing long documents, analyzing complex data, and maintaining continuity across extended conversations. GPT-5 is a reasoning model with 400,000 context window. ChatGPT operates via its Generative Pre-trained Transformer, employing specialized algorithms designed to identify patterns within sequences of data. ChatGPT was developed by OpenAI, an artificial intelligence research company that introduced the tool to the public in November 2022.

The model’s output can also track and profile individuals by collecting information from a prompt and associating this information with the user’s phone number and email. Furthermore, the model lacks comprehension of offensive or discriminatory language. ChatGPT raises significant ethical concerns due to potential biases in its training data, which can manifest in its outputs. While ChatGPT can be helpful for some tasks, there are some ethical concerns that depend on how it is used, including bias, lack of privacy and security, and cheating in education and work. GPT-4.1 and GPT-5 have a knowledge cutoff of June 2024, while GPT-4o’s training data goes up to October 2023.

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. 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 has 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).

• ChatGPT raises significant ethical concerns due to potential biases in its training data, which can manifest in its outputs.
• 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.
• ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events.
• ChatGPT can provide health information to users and assist professionals with diagnosis and staying up to date with clinical guidelines.

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 full disclosure of any use of text-generating tools, and prohibit listing a chatbot as a co-author. In a 2023 blinded study in npj Digital Medicine, researchers tasked with identifying whether abstracts were authentic or generated by ChatGPT were fooled around one-third of the time by the AI-generated abstracts. When assembling training data, the sourcing of copyrighted works may infringe on the copyright holder’s exclusive right to control reproduction, unless covered by exceptions in relevant copyright laws.

A movement named QuitGPT emerged in February 2026 on Reddit, criticizing OpenAI’s ties with the Trump administration, such as a $25 million donation from OpenAI’s president Greg Brockman and his wife to a Trump Super PAC in 2025. Stanford researchers reported that GPT-4 “passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative.” In December 2023, ChatGPT became the first non-human to be included in Nature’s aviator india 10, an annual listicle curated by Nature of people considered to have made significant impact in science.
