What is GPT AI? Generative Pre-Trained Transformers Explained

The partnership will let users create AI videos using hundreds of Disney-owned characters, costumes, and props. The model will roll out to paid ChatGPT users and developers in three versions — Instant, Thinking, and Pro — tailored for everything from everyday tasks to complex reasoning and high-accuracy work. The data underscores OpenAI’s push to win enterprise customers as competition heats up from Google, Anthropic, and open-model rivals, a recurring theme you’ll see in recent updates. OpenAI has added new controls in ChatGPT that let users adjust the chatbot’s warmth, enthusiasm, emoji use, and formatting style.

OpenAI clarifies the reason ChatGPT became overly flattering and agreeable

More and more tech companies and search engines are utilizing the chatbot to automate text or quickly answer user questions/concerns. OpenAI is introducing a new way for users to customize their interactions with ChatGPT. However, users who create an account using their number can’t upgrade to one of OpenAI’s paid plans without verifying their account via an email.
OpenAI has effectively canceled the release of o3 in favor of what CEO Sam Altman is calling a “simplified” product offering. ChatGPT’s weekly active users increased to 300 million by December 2024 and 400 million by February 2025. It took ChatGPT nine months to increase its weekly active users from 100 million in November 2023 to 200 million in August 2024, but it only took less than six months to double that number once more, according to the report. According to a new report from VC firm Andreessen Horowitz (a16z), OpenAI’s AI chatbot, ChatGPT, experienced solid growth in the second half of 2024. The Responses API effectively replaces OpenAI’s Assistants API, which the company plans to discontinue in the first half of 2026. Meta also plans to bolster its presence in India by constructing a large 3GW data center in Jamnagar, Gujarat.

OpenAI to strengthen ChatGPT safeguards after teen suicide lawsuit

It will help organizations in Asia meet their local data sovereignty requirements when using OpenAI’s products. The new program will velwins casino be accessible to users of ChatGPT Enterprise, ChatGPT Edu, and API. The ChatGPT deep research feature is in beta and lets developers connect with GitHub to ask questions about codebases and engineering documents.
Brad Lightcap, OpenAI’s chief operating officer, will lead the company’s global expansion and manage corporate partnerships as CEO Sam Altman shifts his focus to research and products, according to a blog post from OpenAI. The protocol is currently available in the Agents SDK, and support for the ChatGPT desktop app and Responses API will be coming soon, OpenAI CEO Sam Altman said. The organization originally estimated that the best-performing configuration of o3 it tested, o3 high, would cost approximately $3,000 to address a single problem. The image generator was made available to all ChatGPT users on March 31, and went viral for being able to create Ghibli-style photos. More than 130 million users have created over 700 million images since ChatGPT got the upgraded image generator on March 25, according to COO of OpenAI Brad Lightcap. AI researcher Tibor Blaho spotted a new “ImageGen” watermark feature in the new beta of ChatGPT’s Android app.

OpenAI blocked from ‘Cameo’ following trademark lawsuit

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.
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, 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.

Since its launch, the GPT models have brought artificial intelligence (AI) to numerous applications in various industries. In a published research paper, researchers described generative pretraining as the ability to train language models with unlabeled data and achieve accurate prediction. To do that, the GPT models rely on the knowledge they gain after they’re trained with hundreds of billions of parameters on massive language datasets.
By popular request, GPT-4.1 will be available directly in ChatGPT starting today.GPT-4.1 is a specialized model that excels at coding tasks & instruction following. For instance, an analyst could use the company’s slide deck and documents to develop an investment thesis. OpenAI upgraded ChatGPT’s conversational voice mood for all paid users across different markets and platforms.
In addition to that, the chatbot requires 0.34 watt-hours of electricity to operate. The participants were asked to write multiple SAT essays using tools such as OpenAI’s ChatGPT, the Google search engine, or without any tools. They found that ChatGPT users showed minimal brain engagement and consistently fell short in neural, linguistic, and behavioral aspects. OpenAI has started using Google’s AI chips to power ChatGPT and other products, as reported by Reuters. 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… OpenAI says the agent can automatically navigate a user’s calendar, draft editable presentations and slideshows, run code, shop online, and handle complex workflows from end to end, all within a secure virtual environment.

OpenAI CEO says capacity issues will cause product delays

OpenAI launched ChatGPT Gov designed to provide U.S. government agencies an additional way to access the tech. The company then shows the responses to testers, who assess how persuasive the argument is, and finally OpenAI compares the AI models’ responses to human replies for that same post. However, the analysis doesn’t consider the additional energy costs incurred by ChatGPT with features like image generation or input processing.
The company claims o3 is the most advanced reasoning model it has developed, while o4-mini is said to provide a balance of price, speed, and performance. OpenAI introduced o3 in December, stating that the model could solve approximately 25% of questions on FrontierMath, a difficult math problem set. Questions have been raised regarding OpenAI’s transparency and procedures for testing models after a difference in benchmark outcomes was detected by first- and third-party benchmark results for the o3 AI model. 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.” OpenAI leaders have been talking about allowing the open model to link up with OpenAI’s cloud-hosted models to improve its ability to respond to intricate questions, two sources familiar with the situation told TechCrunch. The chatbot provides recommendations, images, and reviews of products in various categories such as fashion, beauty, home goods, and electronics.

Most recently though, headlines around OpenAI have focused on its competition gaining ground, with CEO Sam Altman’s “code red” internal memo shifting company focus toward its flagship chatbot.
In unsupervised training, GPT-3 attempted to produce accurate and realistic results by itself.
On the same day, Disney notably launched a lawsuit against Google alleging “massive” copyright infringement occurring in its AI models.

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.

Due to this and the thousands of hours engineers spent fine-tuning and training the GPT models, they’re able to give fluent answers to almost any input you provide. Additionally, position encoders allow GPT models to prevent ambiguous meanings when a word is used in other parts of a sentence. A transformer model captures more context and improves performance on natural language processing (NLP) tasks. More specifically, the GPT models are neural network-based language prediction models built on the Transformer architecture. The models allow business professionals to rewrite a particular text in a different form.
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.

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.
The update comes as OpenAI races to keep up with Google’s Gemini and Nano Banana Pro in AI image generation. OpenAI has released GPT Image 1.5, a new version of ChatGPT Images that’s faster and better at following instructions and making precise edits. This makes it one of the fastest-growing apps in terms of revenue, outpacing rivals like TikTok, Disney+, and HBO Max. ChatGPT has surpassed $3 billion in global consumer spending on mobile since its 2023 launch.

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. Unlike human therapists, AI tools aren’t bound by doctor-patient confidentiality, he noted. OpenAI unveiled Study Mode, a new ChatGPT feature designed to promote critical thinking by prompting students to engage with material rather than simply receive answers.
