One study analyzed ChatGPT’s responses to 517 questions about software engineering or computer programming posed on Stack Overflow for correctness, consistency, comprehensiveness, and concision. ChatGPT has been used to generate introductory sections and abstracts for scientific articles. Andrew Ng argued that “it’s a mistake to fall for the doomsday hype on AI—and that regulators who do will only benefit vested interests.” Yann LeCun dismissed doomsday warnings of AI-powered misinformation and existential threats to the human race. 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”.
- In July 2023, the FTC launched an investigation into OpenAI, the creator of ChatGPT, over allegations that the company scraped public data and published false and defamatory information.
- 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.
- 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.
- On August 19, 2025, OpenAI launched ChatGPT Go in India, a low-cost subscription plan priced at ₹399 per month, offering ten times higher message, image generation, and file-upload limits, double the memory span compared to the free version, and support for UPI payments.
- 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.
Geoffrey Hinton, one of the “fathers of AI”, voiced concerns that future AI systems may surpass human intelligence. 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”. 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.
App Functionality
A study presented example attacks on ChatGPT, including jailbreaks and reverse psychology. ChatGPT is programmed to reject prompts that may violate its content policy. 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. 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. 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 the 2020s, the rapid advancement of deep learning-based generative artificial intelligence models raised questions about the copyright status of AI-generated works, and about whether copyright infringement occurs when such are trained or used. Over many iterations of ChatGPT, plus users maintained more access to better models than the free tier provided, and access to additional features like voice mode. In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations. 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 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. 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.
Fazit: ChatGPT – Einfach, nützlich und sicher
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. The Pro launch coincided with the release of the o1 model, providing unlimited access to o1 and advanced voice mode.
Applications
- This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT.
- … 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.
- ChatGPT can find more up-to-date information by searching the web, but this doesn’t ensure that responses are accurate, as it may access unreliable or misleading websites.
- Over many iterations of ChatGPT, plus users maintained more access to better models than the free tier provided, and access to additional features like voice mode.
These rankings were used to create “reward models” that were used to fine-tune the model further by using several iterations of proximal policy optimization. The ethics of its development, particularly the use of copyrighted content as training data, have also drawn controversy. The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code. As of 2025, ChatGPT’s website is among the top 5 most-visited websites globally, and has over 800 million active weekly users. By January 2023, ChatGPT had become the fastest-growing consumer software application in history, gaining over 100 million users in two months.
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. On August 19, 2025, OpenAI launched ChatGPT Go in India, a low-cost subscription plan priced at ₹399 per month, offering ten times higher message, image generation, and file-upload limits, double the memory span compared to the free version, and support for UPI payments. In October 2023, OpenAI’s image generation model DALL-E 3 was integrated into ChatGPT Plus and ChatGPT Enterprise. 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. In February 2023, OpenAI launched a premium service, ChatGPT Plus, that costs US$20 per month.
Die Standard-Persönlichkeit von ChatGPT
In March 2023, ChatGPT Plus users got access to third-party plugins and a browsing mode (with Internet access). 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. GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users. 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.

Robin Bauwens, an assistant professor at Tilburg University, found that a ChatGPT-generated peer review report on his article mentioned nonexistent studies. In January 2023, Science “completely banned” LLM-generated text in all its journals; however, this policy was just to give the community time to decide what acceptable use looks like. 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”. This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT.
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”. 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. 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. ChatGPT is a generative artificial intelligence chatbot developed by OpenAI and released in November 2022.
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). These issues have led to its use being restricted in some workplaces and educational institutions and have prompted widespread calls for the regulation of artificial intelligence. It can generate plausible-sounding but incorrect or nonsensical answers known as hallucinations.
Despite its acclaim, the chatbot has been criticized for its limitations and potential for unethical use. At the same time, its release prompted extensive media coverage and public debate about the nature of creativity and the future of knowledge work. The developer has not yet indicated which accessibility features this app supports. Privacy practices may vary based, for example, on the features you use or your age.
Like GPT-5, it comes with a “Thinking” mode for complex problem-solving and an “Instant” mode for fast responses. 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. 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. In November 2023, OpenAI launched GPT-4 Turbo with a 128,000 token context window.
Was ist neu und besser bei dem Sprachmodell GPT-5.1?
This tool allows a user to customize ChatGPT’s behavior for a specific use case. 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. 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.
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 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.” The Guardian questioned whether any content found on the Internet after ChatGPT’s release “can be truly trusted” and called for government regulation. In December 2022, the question-and-answer website Stack Overflow banned the use of ChatGPT for generating answers to questions, citing the factually ambiguous nature of its responses. It found that 52% of the responses contained inaccuracies and 77% were verbose.
A May 2023 statement by hundreds of AI scientists, AI industry leaders, and other public figures demanded that “mitigating the risk of extinction from AI should be a global priority”. In late March 2023, the Italian data protection authority banned ChatGPT in Italy and opened an investigation. 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 10, an annual listicle curated by Nature of people considered to have made significant impact in science. A 2023 study reported that GPT-4 obtained a better score than 99% of humans on the Torrance Tests of Creative Thinking.
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. 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.
