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.
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.

• At launch, OpenAI included more than 3 million GPTs created by GPT Builder users in the GPT Store.
• ChatGPT has a familiar rhythm that most people recognize, even if they cannot describe it.
• At launch, the feature was limited to purchases on Etsy from US users with a payment method linked to their OpenAI account.
• On July 18, 2024, OpenAI released GPT-4o mini, a smaller version of GPT-4o which replaced GPT-3.5 Turbo on the ChatGPT interface.
• 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.

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.

Data Linked to You

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.
GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API. According to OpenAI, it was intended to reduce hallucinations and enhance pattern recognition, creativity, and user interaction. Released in February 2025, GPT-4.5 was described by Altman as a “giant, expensive model”.
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.

• In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks).
• 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).
• As of 2026update, if the user turns off data sharing for privacy, all previous transcripts and projects are permanently deleted without warning.
• As of 2023, there were several pending U.S. lawsuits challenging the use of copyrighted data to train AI models, with defendants arguing that this falls under fair use.
• ChatGPT is a chatbot and AI assistant built on large language model (LLM) technology.

OpenAI’s outsourcing partner was Sama, a training-data company based in San Francisco, California. These labels were used to train a model to detect such content in the future. 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. The service gained 100 million users in two months, making it the fastest-growing consumer software application in history.
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).

Accessibility

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.

Perplexity – AI Search & Chat

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.
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.
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.
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 https://www.luckytwicecasino.eu/ 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.

AI and privacy: ChatGPT conversations found on Google

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”. Geoffrey Hinton, one of the “fathers of AI”, voiced concerns that future AI systems may surpass human intelligence. In July 2023, the US Federal Trade Commission (FTC) issued a civil investigative demand to OpenAI to investigate whether the company’s data security and privacy practices to develop ChatGPT were unfair or harmed consumers. In October 2025, OpenAI banned accounts suspected to be linked to the Chinese government for violating the company’s national security policy. In late March 2023, the Italian data protection authority banned ChatGPT in Italy and opened an investigation.

Model versions

Tackle high-priority tasks.” Not bad. Once you learn to work those switches, ordinary tasks can become a little brighter and more interesting. These are not literal settings, but ways of phrasing your prompts that invite the model to take risks, add texture, or loosen up. Most people type in a prompt, hit enter, and accept whatever answer comes back, like it’s a vending machine dispensing a granola bar. ChatGPT has a familiar rhythm that most people recognize, even if they cannot describe it. Getting the best, or weirdest, takes from the AI chatbot
