As of late 2025, GPT-5 Auto is the default model for most conversations. You can try ChatGPT without an account in many regions, but signing in unlocks advanced features like saved chat history, conversation sharing, custom instructions, and higher usage limits. There are also desktop apps for Windows and macOS that add systemwide shortcuts for quickly launching ChatGPT and sharing your screen, files, or screenshots directly in a chat. In my experience, the web version offers the fullest range of features available. There’s still a free version of ChatGPT, but the Plus and Pro plans can do faster responses and provide access to the latest tools.
MCP, an open-source standard, helps AI models generate more accurate and suitable responses to specific queries, and lets developers create bidirectional links between data sources and AI applications like chatbots. 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 launched a new API feature called Flex processing that allows users to use AI models at a lower cost but with slower response times and occasional resource unavailability. Instead, it should be used as a tool to generate text or complete language-based tasks, and any information provided by the model should be verified with credible sources.” Even answers to questions about computer programming languages, an unlikely source of hallucinations, have proved inaccurate so often that the popular programming question-and-answer site Stack Overflow temporarily banned answers from ChatGPT. Despite decades of using AI, Wall Street professionals report that consistently beating the market with AI, including recent large language models, is challenging due to limited and noisy financial data. In the 2020s, the rapid advancement of deep learning-based generative artificial intelligence models raised questions about the copyright status of AI-generated works, and about whether copyright infringement occurs when such are trained or used.
OpenAI’s AI voice assistant now has advanced feature
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. The system is designed to prevent models from giving advice that could potentially lead to harmful attacks, as stated in OpenAI’s safety report. OpenAI has rolled out a new system to monitor its AI reasoning models, o3 and o4 mini, for biological and chemical threats. 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.
Although ChatGPT only launched back in 2022, and is still fairly young in the grand scheme of things, it has seen countless updates and new version launches (also known as “models”). For example, there are chatbots that are rules-based in the sense that they’ll give canned responses to questions. While OpenAI had previously allowed users to ask ChatGPT questions without signing in, responses were restricted to the chatbot’s last training update. ChatGPT users will see an updated “chain of thought” that shows more of the model’s “reasoning” steps and how it arrived at answers to questions. ChatGPT has experienced significant growth recently due to the launch of new models and features, such as GPT-4o, with multimodal capabilities. 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.
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.”
ChatGPT is a generative artificial intelligence chatbot developed by OpenAI.
OpenAI has said that individuals in “certain jurisdictions” (such as the EU) can object to the processing of their personal information by its AI models by filling out this form. That’s because ChatGPT lacks context awareness — in other words, the generated code isn’t always appropriate for the specific context in which it’s being used. Due to the nature of how these models work, they don’t know or care whether something is true, only that it looks true. And nonprofit organization Solana officially integrated the chatbot into its network with a ChatGPT plug-in geared toward end users to help onboard into the web3 space.
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. O3-pro is available for ChatGPT and Team users and in the API, while Enterprise and Edu users will get access in the third week of June. 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.

It is capable of writing software, answering codebase questions, running tests, and proposing pull requests. In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks). The integration used ChatGPT to write prompts for DALL-E guided by conversations with users. According to TechCrunch, it is a service based on o3 that combines advanced reasoning and web search capabilities to make comprehensive reports within 5 to 30 minutes.
Although OpenAI notes it may not grant every request since it must balance privacy requests against freedom of expression “in accordance with applicable laws”. This includes the ability to make requests for deletion of AI-generated references about you. There are multiple AI-powered chatbot competitors such as Together, Google’s Gemini and Anthropic’s Claude, and developers are creating open source alternatives. OpenAI allows users to save chats in the ChatGPT interface, stored in the sidebar of the screen.
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. It is unclear whether OpenAI intends to launch the social network as a standalone application or incorporate it into ChatGPT. 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. 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 now reveals more of its o3-mini model’s thought process
In July 2023, the FTC launched an investigation into OpenAI, the creator of ChatGPT, over allegations that the company scraped public data and published false and defamatory information. Italian regulators assert that ChatGPT was exposing minors to age-inappropriate content, and foxygold casino that OpenAI’s use of ChatGPT conversations as training data could violate Europe’s General Data Protection Regulation. ChatGPT also provided an outline of how human reviewers are trained to reduce inappropriate content and to attempt to provide political information without affiliating with any political position. GPT-4o’s ability to generate images was released later, in March 2025, when it replaced DALL-E 3 in ChatGPT.

OpenAI releases its GPT-4.1 and GPT-4.1 mini AI models in ChatGPT
- These labels were used to train a model to detect such content in the future.
- Scientists at the University of California, Riverside, estimated in 2023 that a series of 5 to 50 prompts to ChatGPT needs approximately 0.5 liters (0.11 imp gal; 0.13 U.S. gal) of water for Microsoft servers’ cooling.

- The integration used ChatGPT to write prompts for DALL-E guided by conversations with users.
I’ve covered the models and modes above, but here’s a reminder of all the core features (as of October 2025). Apart from models, there are modes and tools in ChatGPT that allow you to go beyond basic chatting. To get started, simply go to chatgpt.com or install the official app from the Apple App Store or Google Play. There’s even a Projects feature that keeps all your chats organized, plus a Library to manage all your generated images. This year alone, OpenAI peppered us with new models, modes, and features to play with inside the AI.
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.
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 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 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.
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. 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. 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 feature acts as a conversational search engine, providing more comprehensive and accurate answers by scouring multiple sources simultaneously.
