This week, ChatGPT is on track to reach 700M weekly active users — up from 500M at the end of March and 4× since last year. Nick Turley, OpenAI’s VP and head of the ChatGPT app, highlighted the app’s growth on X, noting it has quadrupled in size over the past year. Despite unveiling GPT-5 as a “one-size-fits-all” AI, OpenAI is still offering several legacy AI options, including GPT-4o, GPT-4.1, and o3. Since its May 2023 launch, ChatGPT’s mobile app has amassed $2 billion in global consumer spending, dwarfing competitors like Claude, Copilot, and Grok by roughly 30 times, according to Appfigures. OpenAI introduced its most affordable subscription plan, ChatGPT Go, in India, priced at 399 rupees per month (approximately $4.57).

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 ».

OpenAI has updated ChatGPT to use information from your previous conversations

While OpenAI has a similar deleted data retention policy for ChatGPT, the retention period for ChatGPT is only 30 days, which is 60 days shorter than Operator’s. OpenAI launched ChatGPT Gov designed to provide U.S. government agencies an additional way to access the tech. OpenAI first previewed the model in December alongside a more capable system called o3. OpenAI announced a new AI “agent” called deep research that’s designed to help people conduct in-depth, complex research using ChatGPT. To use ChatGPT in any form through the native mobile app, you will still need to be logged in. In response to pressure from rivals like DeepSeek, OpenAI is changing the way its o3-mini model communicates its step-by-step “thought” process.

Munich court says ChatGPT violated music copyright laws

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 foxygold casino ChatGPT features like web browsing, coding, and image processing and generation.

• ChatGPT, software that allows a user to ask it questions using conversational, or natural, language.

Paid version

OpenAI’s ChatGPT now offers new funtions for business users, including integrations with various cloud services, meeting recordings, and MCP connection support for connecting to tools for in-depth research. Some people also wonder whether there will be a feature that allows multiple users to join the chat, similar to a study group. OpenAI has introduced ChatGPT Agent, which completes a wide variety of computer-based tasks on behalf of users and combines several capabilities like Operator and Deep Research, according to the company.
More and more tech companies and search engines are utilizing the chatbot to automate text or quickly answer user questions/concerns. Both the free version of ChatGPT and the paid ChatGPT Plus are regularly updated with new GPT models. ChatGPT is a general-purpose chatbot that uses artificial intelligence to generate text after a user enters a prompt, developed by tech startup OpenAI.

In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations. ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance. The latest model, which launched in August 2025, is GPT-5 and is hailed as being the “smartest, fastest, most useful model yet”. ChatGPT can be used for many purposes, including answering questions and explaining tricky concepts, drafting essays, writing code and even advising on health queries. But OpenAI recently disclosed a bug, since fixed, that exposed the titles of some users’ conversations to other people on the service. Several tools claim to detect ChatGPT-generated text, but in our tests, they’re inconsistent at best.
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.

GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API. 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. 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. GPT-4o (« o » for « omni ») is a multilingual, multimodal generative pre-trained transformer developed by OpenAI and released in May 2024. In November 2023, OpenAI launched GPT-4 Turbo with a 128,000 token context window.

GPT-4.5

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.
Open AI introduced a new section called “library” to make it easier for users to create images on mobile and web platforms, per the company’s X post. OpenAI has released two new reasoning models, o3 and o4 mini, just two days after launching GPT-4.1. Flex processing is available in beta on the o3 and o4-mini reasoning models for non-production tasks like model evaluations, data enrichment, and asynchronous workloads. OpenAI introduced o3 in December, stating that the model could solve approximately 25% of questions on FrontierMath, a difficult math problem set. The company skipped that step — sending safety cards for GPT-4.1 — claiming in a statement to TechCrunch that “GPT-4.1 is not a frontier model, so there won’t be a separate system card released for it.”
Samantha Lock of The Guardian noted that it was able to generate « impressively detailed » and « human-like » text. Kevin Roose of The New York Times called it « the best artificial intelligence chatbot ever released to the general public ». 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.
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. ChatGPT can produce correct answers to medical exam and licensing questions, for example the United States Medical Licensing Examination and the Specialty Certificate Examination in Dermatology. The chatbot can assist patients seeking clarification about their health. Many companies adopted ChatGPT and similar chatbot technologies into their product offers. This has led to concern over the rise of AI slop whereby « 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. »
ChatGPT includes a built-in image generator that’s powered by GPT-4o. Ask it to find, for example, the best humidifier available — and specify any features or a price range. You can probably tell by now that ChatGPT is far more than a simple chatbot. Once you’ve chosen a model and even a mode or tool in ChatGPT, it’s time to finally ask something.
