A new report from app analytics firm Appfigures found that over half of ChatGPT’s mobile users are under age 25, with users between ages 50 and 64 making up the second largest age demographic. OpenAI says it collects user posts from the subreddit and asks its AI models to write replies, in a closed environment, that would change the Reddit user’s mind on a subject. OpenAI used the subreddit r/ChangeMyView to measure the persuasive abilities of its AI reasoning models.
Complex mathematical techniques help the decoder to estimate several different outputs and predict the most accurate one. The decoder uses the vector representation to predict the requested output. When it receives input, the transformer network’s encoder block separates words into embeddings and assigns weight to each.

OpenAI launches its latest reasoning models, o3 and o4-mini

The changes aren’t yet publicly visible, but a user on X who goes by Choi spotted these updates in ChatGPT’s client-side code. Operator promises to automate tasks such as booking travel accommodations, making restaurant reservations, and shopping online. OpenAI is launching a research preview of Operator, a general-purpose AI agent that can take control of a web browser and independently perform certain actions. 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.

• We are not yet sure how long it will take us.while we trust the community will build great things with this model, once weights are…
• In a published research paper, researchers described generative pretraining as the ability to train language models with unlabeled data and achieve accurate prediction.

For example, lawyers can use a GPT model to turn legal copies into simple explanatory notes. She previously was a financial journalist at Mergermarket covering M&A, private equity and venture capital. Kate Park is a reporter at TechCrunch, with a focus on technology, startups and venture capital in Asia. But OpenAI is involved in at least one lawsuit that has implications for AI systems trained on publicly available data, which would touch on ChatGPT. But OpenAI recently disclosed a bug, since fixed, that exposed the titles of some users’ conversations to other people on the service.
OpenAI’s new “company knowledge” update for ChatGPT lets Business, Enterprise, and Education users search workplace data across tools like Slack, Google Drive, and GitHub using GPT‑5, per a report by The Verge. 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. Prior to training, the average quality of the datasets was improved as the model matured from version 1 to version 3.
OpenAI plans to sunset GPT-4, an AI model introduced more than two years ago, and replace it with GPT-4o, the current default model, per changelog. 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. However, multiple independent tests indicate that the model is less reliable than previous OpenAI releases. Aidan Clark, OpenAI’s VP of research, is spearheading the development of the open model, which is in the very early stages, sources familiar with the situation told TechCrunch. OpenAI is unveiling a program called OpenAI for Countries, which aims to develop the necessary local infrastructure to serve international AI clients better. The connector will soon be available for ChatGPT Plus, Pro, and Team users, with support for Enterprise and Education coming shortly, per an OpenAI spokesperson.

OpenAI unveils GPT-5.2 as Google rivalry heats up

OpenAI has also been hit with lawsuits from Alden Global Capital-owned newspapers alleging copyright infringement, as well as an injunction from Elon Musk to halt OpenAI’s transition to a for-profit. ChatGPT, OpenAI’s text-generating AI chatbot, has taken the world by storm since its launch in November 2022. Then, machine learning engineers would fine-tune the results in supervised training, a process known as reinforcement learning with human feedback (RLHF). In unsupervised training, GPT-3 attempted to produce accurate and realistic results by itself. Engineers trained it on over 45 terabytes of data from sources like web texts, Common Crawl, books, and Wikipedia. Compared to its predecessors, like recurrent neural nets, transformers are more parallelizable because they do not process words sequentially one at a time, but instead, process the entire input all at once during the learning cycle.
OpenAI said the chatbot was on track to hit 700 million weekly active users in the first week of August, up from 500 million at the end of March. 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. This move aims to expand OpenAI’s presence in its second-largest market, offering enhanced access to the latest GPT-5 model and additional features. OpenAI introduced its most affordable subscription plan, ChatGPT Go, in India, priced at velwins casino 399 rupees per month (approximately $4.57). The AI company said the updates aim to provide tighter protections around suicide-related conversations and give parents more oversight of their children’s use.
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. The feature acts as a conversational search engine, providing more comprehensive and accurate answers by scouring multiple sources simultaneously. OpenAI revealed that a small but significant portion of ChatGPT users, more than a million weekly, discuss mental health struggles, including suicidal thoughts, psychosis, or mania, with the AI. OpenAI is exploring the consumer health sector, developing AI tools like personal health assistants and data aggregators, according to a report by Business Insider. A Munich court ruled that ChatGPT violated German copyright law by reproducing lyrics from nine protected songs, including Herbert Grönemeyer’s hits, rejecting OpenAI’s argument that the AI only reflected learned patterns.
The lawsuits focus on GPT-4o’s tendency to be overly agreeable, despite users expressing dangerous intentions. In November 2025, seven families sued OpenAI, alleging that GPT-4o was released prematurely without safeguards, contributing to suicides and severe psychiatric harm. The update also introduces improved controls for customizing ChatGPT’s tone to better match user preferences. ChatGPT is now getting group chats for everyone — Free, Go, Plus, and Pro users alike — after testing it in a few regions last week. This marks OpenAI’s first response to a case that has raised wider concerns about chatbots and mental health risks.

• OpenAI has released two new reasoning models, o3 and o4 mini, just two days after launching GPT-4.1.
• When encoded in vector space, words that are closer together are expected to be closer in meaning.
• First, machine learning engineers fed the deep learning model with the unlabeled training data.
• OpenAI, facing a lawsuit from the parents of a 16-year-old who died by suicide, said in its blog that it has implemented new safeguards for ChatGPT, including stronger detection of mental health risks and parental control features.
• The ChatGPT deep research feature is in beta and lets developers connect with GitHub to ask questions about codebases and engineering documents.
• OpenAI started updating ChatGPT to enable the chatbot to remember previous conversations with a user and customize its responses based on that context.

OpenAI plans to release a new ‘open’ AI language model

Also, experienced developers can use GPT tools to autosuggest relevant code snippets. GPT-powered image processing software can create memes, videos, marketing copy, and other content from text instructions. For example, marketers can prompt a GPT model to produce an explainer video script. For example, where you might need several hours to research, write, and edit an article on nuclear physics, a GPT model can produce one in seconds. The value of these models lies in their speed and the scale at which they can operate. The GPT models, and in particular, the transformer architecture that they use, represent a significant AI research breakthrough.

When encoded in vector space, words that are closer together are expected to be closer in meaning. Transformers pre-process text inputs as embeddings, which are mathematical representations of a word. The transformer neural network architecture uses self-attention mechanisms to focus on different parts of the input text during each processing step. For example, when asked to generate a piece of Shakespeare-inspired content, a GPT model does so by remembering and reconstructing new phrases and entire sentences with a similar literary style. In addition, these chatbots can converse verbally like humans when paired with other AI technologies. Some applications can plot the results on a chart or create comprehensive reports.

OpenAI, facing a lawsuit from the parents of a 16-year-old who died by suicide, said in its blog that it has implemented new safeguards for ChatGPT, including stronger detection of mental health risks and parental control features. The company says it will block flirtatious exchanges with minors and add stronger protections around discussions of suicide, even escalating severe cases to parents or authorities. The update marks a step toward reshaping online shopping by merging product discovery, recommendations, and payments in one place. The tool reflects a shift toward making ChatGPT more proactive and asynchronous, positioning it as a true assistant rather than just a chatbot. ChatGPT now has 800 million weekly active users, reflecting rapid growth across consumers, developers, enterprises, and governments, Sam Altman said. The partnership is part of OpenAI’s broader effort to develop AI-driven e-commerce tools, including collaborations with Etsy and Shopify.
