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 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.

A new MIT study suggests that ChatGPT might be harming critical thinking skills

OpenAI charges $150 for every million tokens (about 750,000 words) input into the model and $600 for every million tokens the model produces. OpenAI says its o1-pro uses more computing than its o1 “reasoning” AI model to deliver “consistently better responses.” It’s only accessible to select developers who have spent at least $5 on OpenAI API services. The company claims they are improved versions of what was already there and that they hallucinate less. Showing ChatGPT users a tiny disclaimer that the chatbot can make mistakes clearly isn’t enough. Personal data has to be accurate,” said Joakim Söderberg, data protection lawyer at Noyb, in a statement. OpenAI has updated its AI voice assistant with improved chatting capabilities, according to a video posted on Monday (March 24) to the company’s official media channels.
In a post on X, Altman said that, in the coming months, OpenAI will release a model called GPT-5 that “integrates a lot of OpenAI’s technology,” including o3, in ChatGPT and its API. It’s unclear when these agentic tools might launch or which customers will be eligible to buy them. We trained a new model that is good at creative writing (not sure yet how/when it will get released). The company has mostly concentrated on challenges in rigid, predictable areas such as math and programming. He posted a lengthy sample from the model given the prompt “Please write a metafictional literary short story about AI and grief.” OpenAI has not extensively explored the use of AI for writing fiction. OpenAI CEO Sam Altman said, in a post on X, that the company has trained a “new model” that’s “really good” at creative writing.

ChatGPT handles over a million suicide-related conversations weekly

The startup has launched an update to Advanced Voice that enables users to converse with ChatGPT out loud in a more natural and fluid sound. This is the chatbot’s approach to becoming a more effective educational tool, rather than simply providing answers to prompts. ChatGPT now receives 2.5 billion prompts daily from users worldwide, including roughly 330 million from the U.S. General Services Administration (GSA) added OpenAI, Google, and Anthropic to its approved AI vendor list, allowing agencies to access these tools through preset contracts without negotiating pricing.

We will see how handling troubling statements produced by ChatGPT will play out over the next few months as velwins casino tech and legal experts attempt to tackle the fastest moving target in the industry. That’s a problem when you’re using it to do your homework, sure, but when it accuses you of a crime you didn’t commit, that may well at this point be libel. ChatGPT is AI-powered and utilizes LLM technology to generate text after a prompt. For example, there are chatbots that are rules-based in the sense that they’ll give canned responses to questions. A chatbot can be any software/system that holds dialogue with you/a person but doesn’t necessarily have to be AI-powered. A Brooklyn-based 3D display startup Looking Glass utilizes ChatGPT to produce holograms you can communicate with by using ChatGPT.

• This feature is rolling out to ChatGPT Pro and Plus users first, excluding those in the U.K., EU, Iceland, Liechtenstein, Norway, and Switzerland.
• OpenAI allows users to save chats in the ChatGPT interface, stored in the sidebar of the screen.
• 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.
• Prior to training, the average quality of the datasets was improved as the model matured from version 1 to version 3.
• While many chatbots only respond to basic verbal prompts, the GPT models can produce chatbots with conversational AI capabilities.

Referrals from ChatGPT to news sites are rising but not enough to offset search declines

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. 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 launch date and whether it will be standalone or integrated with ChatGPT and Sora remain unclear. On November 5, OpenAI announced that over 1 million businesses globally now use its products, making it the fastest-growing business platform in history.

• Meanwhile, founding leader Joanne Jang is spinning up a new unit called OAI Labs, focused on prototyping fresh ways for people to collaborate with AI.
• Researchers at Stanford University have observed that therapy chatbots powered by large language models can sometimes stigmatize people with mental health conditions or respond in ways that are inappropriate or could be harmful.
• 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.
• Kate Park is a reporter at TechCrunch, with a focus on technology, startups and venture capital in Asia.
• 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.
• That’s more than double the volume reported by CEO Sam Altman just eight months ago, highlighting the chatbot’s explosive growth.

OpenAI has begun testing a feature that lets new ChatGPT users sign up with only a phone number — no email required. Changes to ChatGPT’s code base suggest that Operator will be available as an early research preview to users on the $200 Pro subscription plan. 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.
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.

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.
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.
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.

OpenAI intends to release several “agent” products tailored for different applications, including sorting and ranking sales leads and software engineering, according to a report from The Information. The tools are part of OpenAI’s new Responses API, which enables enterprises to develop customized AI agents that can perform web searches, scan through company files, and navigate websites, similar to OpenAI’s Operator product. OpenAI wants to incorporate Anthropic’s Model Context Protocol (MCP) into all of its products, including the ChatGPT desktop app. The company has updated its policies to allow ChatGPT to generate images of public figures, hateful symbols, and racial features when requested.
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. However, the company has now “evolved” its approach, as stated in a blog post published by Joanne Jang, the lead for OpenAI’s model behavior. OpeanAI intends to release its “first” open language model since GPT-2 “in the coming months.” The company plans to host developer events to gather feedback and eventually showcase prototypes of the model. 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. OpenAI may launch several new AI models, including GPT-4.1, soon, The Verge reported, citing anonymous sources.
The update enables real-time conversations, and the AI assistant is said to be more personable and interrupts users less often. OpenAI had previously declined such prompts due to the potential controversy or harm they may cause. OpenAI made a notable change to its content moderation policies after the success of its new image generator in ChatGPT, which went viral for being able to create Studio Ghibli-style images. The Arc Prize Foundation, which develops the AI benchmark tool ARC-AGI, has updated the estimated computing costs for OpenAI’s o3 “reasoning” model managed by ARC-AGI. OpenAI started updating ChatGPT to enable the chatbot to remember previous conversations with a user and customize its responses based on that context.
