ChatGPT: Everything you need to know about the AI-powered chatbot

Noam Brown, who heads AI reasoning research at OpenAI, thinks that certain types of AI models for “reasoning” could have been developed 20 years ago if researchers had understood the correct approach and algorithms. OpenAI will discontinue its largest AI model, GPT-4.5, from its API even though it was just launched in late February. GPT-4.5 will be available in a research preview for paying customers. 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. OpenAI is preparing to launch an AI system that will be openly accessible, allowing users to download it for free without any API restrictions.

• Furthermore, in response to competition from rivals like Chinese AI company DeepSeek R1, OpenAI rolled out trials for its newest lightweight model and deep research, accessible even to free-tier users (with limited access).
• GPT-4.1 would be an update of OpenAI’s GPT-4o, which was released last year.
• Instead, they’re the interface we use to interact with large language models.
• This prediction and adjustment happens billions of times, so the LLM is constantly refining its understanding of language and getting better at identifying patterns and predicting future words.
• A celebrated contributor to various news outlets, her sharp insights and relatable storytelling have earned her a loyal readership.

However, users have noted that there are some character limitations after around 500 words. Both the free version of ChatGPT and the paid ChatGPT Plus are regularly updated with new GPT models. 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. Operator promises to automate tasks such as booking travel accommodations, making restaurant reservations, and shopping online. 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 will remove its largest AI model, GPT-4.5, from the API, in July

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. OpenAI introduced o3 in December, stating that the model could solve approximately 25% of questions on FrontierMath, a difficult math problem set. Epoch AI, the research institute behind FrontierMath, discovered that o3 achieved a score of approximately 10%, which was significantly lower than OpenAI’s top-reported score. After introducing a data residency program in Europe in February, OpenAI has now launched a similar program in Asian countries including India, Japan, Singapore, and South Korea. The new program will be accessible to users of ChatGPT Enterprise, ChatGPT Edu, and API.

What are some sample everyday uses for ChatGPT?

OpenAI did not respond to a request for comment on potential copyright and plagiarism concerns about training data or on user privacy and data protection. The bots are intended to reference details from previous conversations with users while sticking to their designated personas, which can range from a chef to a doctor or a classical composer. Unless their human conversation partners bring up the subject, the bots are also trained to steer clear of controversial or potentially emotionally inflammatory subjects. BI reported that the proactive chatbot effort is being coordinated in partnership with Alignerr, a company that employs contractors with expertise across various fields to help label the training data AI models ingest.

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. Several major school systems and colleges, including New York City Public Schools, have banned ChatGPT from their networks and devices. They claim that the AI impedes the learning process by promoting plagiarism and misinformation, a claim that not every educator agrees with. OpenAI allows users to save chats in the ChatGPT interface, stored in the sidebar of the screen. Due to the nature of how these models work, they don’t know or care whether something is true, only that it looks true. 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.

But they hallucinate more than several of OpenAI’s previous models. ChatGPT relies on large language models (LLMs), enabling it to understand your questions and provide human-like responses. Sometimes it does it so convincingly and naturally, you might forget it’s not actually thinking.

• ChatGPT relies on large language models (LLMs), enabling it to understand your questions and provide human-like responses.
• The bot’s summaries will leave out key details — enough to make the answer a bit inscrutable in some cases, but this prompt can spark a useful discussion.
• OpenAI allows users to save chats in the ChatGPT interface, stored in the sidebar of the screen.
• Please logout and then login again, you will then be prompted to enter your display name.

The company has mostly concentrated on challenges in rigid, predictable areas such as math and programming. And it turns out that it might not be that great at creative writing at all. 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. Lightcap, who previously worked with Altman at Y Combinator, joined the Microsoft-backed startup in 2018. OpenAI also said Mark Chen would step into the expanded role of chief research officer, and Julia Villagra will take on the role of chief people officer.

All ChatGPT users on the web and iOS/Android now have a Library where images are automatically saved, letting you revisit, reuse or edit them without digging through old chats. It has also been integrated into educational apps, customer service bots and even Apple products via Apple Intelligence and Siri. On the flip side, perhaps a developer makes a dating chatbot, whose instructions say to never capitalize the first word of a response, to use “lol” and winking faces often, and to take on a casual tone. All of a sudden, you aren’t chatting with a ChatGPT clone, but a bot that doesn’t sound quite so robotic.
