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. 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.
OpenAI has launched a new feature for ChatGPT deep research to analyze code repositories on GitHub. The coding agent may take anywhere from one to 30 minutes to complete tasks such as writing simple features, fixing bugs, answering questions about your codebase, and running tests. The startup has launched an foxygold casino update to Advanced Voice that enables users to converse with ChatGPT out loud in a more natural and fluid sound. OpenAI has unveiled o3-pro, an enhanced version of its o3, a reasoning model that the chatGPT maker launched earlier this year.

ZDNET’s recommendations are based on many hours of testing, research, and comparison shopping. When asked if there really was such a Greek myth, ChatGPT apologized and replied that there was no such myth but that it had created a fable based on its understanding of Greek mythology. The model can add two-digit numbers (e.g., 23 + 56) with complete accuracy, but for multiplying two-digit numbers (e.g., 23 × 56), it produces the right answer only about 30 percent of the time. By means of a series of such tests, a computer’s success at “thinking” can be measured by its probability of being misidentified as the human subject.
ChatGPT is a generative artificial intelligence chatbot developed by OpenAI.

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. 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. ChatGPT has been used to generate introductory sections and abstracts for scientific articles. Additionally, using a model’s outputs might violate copyright, and the model creator could be accused of vicarious liability and held responsible for that copyright infringement.
OpenAI is expanding its affordable ChatGPT Go plan, priced under $5, to 16 new countries across Asia, including Afghanistan, Bangladesh, Bhutan, Brunei Darussalam, Cambodia, Laos, Malaysia, Maldives, Thailand, Vietnam, and Pakistan. OpenAI is partnering with Walmart to allow users to browse products, plan meals, and make purchases through ChatGPT, with support for third-party sellers expected later this fall. A new Apptopia analysis suggests ChatGPT’s mobile app growth may be leveling off, with global download growth slowing since April. Unlike other AI browsers, Atlas is open to all users and will soon come to Windows, iOS, and Android, as OpenAI aims to make ChatGPT the go-to tool for browsing the web. The feature acts as a conversational search engine, providing more comprehensive and accurate answers by scouring multiple sources simultaneously.

Sam Altman aims to make ChatGPT more personalized by tracking every aspect of a person’s life

OpenAI suggests traits like “Chatty,” “Encouraging,” and “Gen Z.” However, some users reported that the new options have disappeared, so it’s possible they went live prematurely. Some users found they can specify a preferred name or nickname and “traits” they’d like the chatbot to have. The feature will start rolling out to ChatGPT Plus, Team, and Pro users around the globe this week. OpenAI has begun testing a feature that lets new ChatGPT users sign up with only a phone number — no email required. In a follow-up to its 2023 poll on ChatGPT usage among young people, Pew asked ~1,400 U.S.-based teens ages 13 to 17 whether they’ve used ChatGPT for homework or other school-related assignments. OpenAI says that ChatGPT Gov enables agencies to more easily manage their own security, privacy, and compliance, and could expedite internal authorization of OpenAI’s tools for the handling of non-public sensitive data.

• In February 2023, OpenAI launched a premium service, ChatGPT Plus, that costs US$20 per month.
• 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 update enables real-time conversations, and the AI assistant is said to be more personable and interrupts users less often.
• OpenAI’s new Applications CEO, Fidji Simo, called Pulse the first step toward bringing high-level personal support to everyone, starting with Pro users.
• A new Apptopia analysis suggests ChatGPT’s mobile app growth may be leveling off, with global download growth slowing since April.

OpenAI now allows developers to build interactive apps directly inside ChatGPT, with early partners like Booking.com, Expedia, Spotify, Figma, Coursera, Zillow, and Canva already onboard. ChatGPT now has 800 million weekly active users, reflecting rapid growth across consumers, developers, enterprises, and governments, Sam Altman said. In some of these countries, users can pay in local currencies, while in others, payments are required in USD, with final costs varying due to local taxes.

Can ChatGPT be detected?

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. The fine-tuning process involved supervised learning and reinforcement learning from human feedback (RLHF). 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. Users can interact with ChatGPT through text, audio, and image prompts.
OpenAI rolled out new tools designed to help developers and businesses build AI agents — automated systems that can independently accomplish tasks — using the company’s own AI models and frameworks. The company’s CEO Sam Altman said on Wednesday, however, that the release of the image generation feature to free users would be delayed due to higher demand than the company expected. The company has updated its policies to allow ChatGPT to generate images of public figures, hateful symbols, and racial features when requested. The offer will let millions of students use OpenAI’s premium service, which offers access to the company’s GPT-4o model, image generation, voice interaction, and research tools that are not available in the free version. The new models stand out from previous reasoning models because they can use ChatGPT features like web browsing, coding, and image processing and generation.

• Many companies adopted ChatGPT and similar chatbot technologies into their product offers.
• Developers can use GPT-4.5 through OpenAI’s API until July 14; then, they will need to switch to GPT-4.1, which was released on April 14.
• Unlike other AI browsers, Atlas is open to all users and will soon come to Windows, iOS, and Android, as OpenAI aims to make ChatGPT the go-to tool for browsing the web.
• The partnership will let users create AI videos using hundreds of Disney-owned characters, costumes, and props.
• The chatbot uses GPT-4, a large language model that uses deep learning to produce human-like text.

ChatGPT (based on GPT-4) was better able to translate Japanese to English when compared to Bing, Bard, and DeepL Translator in 2023. In 2023, OpenAI worked with a team of 40 Icelandic volunteers to fine-tune ChatGPT’s Icelandic conversation skills as a part of Iceland’s attempts to preserve the Icelandic language. Scientists at the University of California, Riverside, estimated in 2023 that a series of 5 to 50 prompts to ChatGPT needs approximately 0.5 liters (0.11 imp gal; 0.13 U.S. gal) of water for Microsoft servers’ cooling. TrendForce estimated that 30,000 Nvidia GPUs (each costing approximately $10,000–15,000) were used to power ChatGPT in 2023.
OpenAI unveiled Pulse, a new ChatGPT feature that delivers personalized morning briefings overnight, encouraging users to start their day with the app. OpenAI launched a new AI shopping feature in ChatGPT ahead of the peak holiday shopping window to help users research potential purchases. On the same day, Disney notably launched a lawsuit against Google alleging “massive” copyright infringement occurring in its AI models. Free users are limited in how many images they can generate per day or in a rolling window (see OpenAI’s support page for current rate limits).

OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations. 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. 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.
Within five days of its introduction, more than one million users had signed up for a free account to interact with ChatGPT. For example, “the cat sat on the mat” is more likely to occur in English than “sat the the mat cat on” and thus would be more likely to appear in a ChatGPT response. Judges in the US and Pakistan have endorsed using ChatGPT to investigate legal questions during a case. In an American civil lawsuit, attorneys were sanctioned for filing a legal motion generated by ChatGPT containing fictitious legal decisions. 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.
