The language models used in Romibet ChatGPT are specifically optimized for dialogue and were trained using reinforcement learning from human feedback (RLHF). GPT-4o is the most advanced version accessible to everyone, handling text, images and audio as input and output. ChatGPT relies on large language models (LLMs), enabling it to understand your questions and provide human-like responses. In late March 2023, the Italian data protection authority banned ChatGPT in Italy and opened an investigation. OpenAI said it has taken steps to effectively clarify and address the issues raised; an age verification tool was implemented to ensure users are at least 13 years old.
Paid tier
So far, users can make single-item purchases from domestic sellers on online marketplace Etsy, as well as some merchants on Shopify’s e-commerce platform. In August 2025, OpenAI released GPT-5, its fastest and smartest model to date, and the current language model for ChatGPT. OpenAI claims that GPT-5 outperforms past models in math, real-world coding, multimodal understanding and health knowledge, and is also less likely to hallucinate or make false claims. Teachers are concerned that students will use it to cheat, prompting some schools to completely block access to it. Not only can ChatGPT generate working computer code of its own (in many different languages), but it can also translate code from one language to another, and debug existing code.
Notable ChatGPT Updates
OpenAI has already gotten a glimpse of this future through its o1 model, and the results have been mixed. AI agents represent stage three of AGI, enhancing ChatGPT’s reasoning abilities and enabling it to complete a broader range of tasks without human assistance. OpenAI initially releases this feature to users who pay for the Plus, Team or Enterprise plan.

This often leads to what experts call “hallucinations,” where the output generated is stylistically correct, but factually wrong. Instead of a list of websites, though, it’ll provide users with a simple list of answers. ChatGPT became one of the fastest-growing apps in history, amassing hundreds of millions of users. ChatGPT can produce correct answers to medical exam and licensing questions, for example the United States Medical Licensing Examination and the Specialty Certificate Examination in Dermatology. The Guardian questioned whether any content found on the Internet after ChatGPT’s release “can be truly trusted” and called for government regulation. This has led to concern over the rise of what has come to be called “synthetic media” and “AI slop” which are generated by AI and rapidly spread over social media and the internet.
- It currently uses GPT-5, a generative pre-trained transformer (GPT), to generate text, speech, and images in response to user prompts.
- In one instance, ChatGPT generated a rap in which women and scientists of color were asserted to be inferior to white male scientists.
- OpenAI supports limited, no-login access in many regions, so you can try ChatGPT instantly.
- ChatGPT is powered by a large language model made up of neural networks trained on a massive amount of information from the internet, including Wikipedia articles and research papers.
- A 2023 study reported that GPT-4 obtained a better score than 99% of humans on the Torrance Tests of Creative Thinking.
- In my experience, the web version offers the fullest range of features available.

Can I search the web with ChatGPT?
Similar to a phone’s auto-complete feature, ChatGPT uses a prediction model to guess the most likely next word based on the context it has been provided. ChatGPT Team lets companies create shared workspaces with settings that apply to all users, as well as the ability to share proprietary data sets. OpenAI announces the ChatGPT Pro plan, a new premium plan for ChatGPT users to access even more features.
I’ve covered the models and modes above, but here’s a reminder of all the core features (as of October 2025). This is used to not only help the model determine the best output, but it also helps improve the training process, enabling it to answer questions more effectively. Here’s how it works, its use cases, how to access it, its limitations, notable updates and future outlook. Recently, OpenAI made ChatGPT’s image generation capabilities free for all users, albeit with a limited number of monthly uses. Beyond text, ChatGPT can generate original images and videos through its integrated tools. If you prefer to keep using Dall-E 3 (its first image generator), you can still access it through the Dall-E GPT.

- The languages tested were Polish, French, Korean, Spanish, Arabic, Tagalog, and Amharic.
- OpenAI announced the addition of product recommendations on ChatGPT when users implied shopping intent in their queries.
- It was trained on massive amounts of data from books and the internet — websites, Wikipedia, Reddit threads, news sites and much, much more.
- The paid version of ChatGPT also offers features like image and voice inputs and integrations with other OpenAI services like the image generator DALL-E.
- Geoffrey Hinton, one of the “fathers of AI”, voiced concerns that future AI systems may surpass human intelligence.
- Not only can ChatGPT generate working computer code of its own (in many different languages), but it can also translate code from one language to another, and debug existing code.

By January 2023, ChatGPT had become the fastest-growing consumer software application in history, gaining over 100 million users in two months. As of 2025, ChatGPT’s website is among the 5 most-visited websites globally, and has over 800 million active weekly users.

OpenAI’s outsourcing partner was Sama, a training-data company based in San Francisco, California. ZDNET’s recommendations are based on many hours of testing, research, and comparison shopping. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.

ChatGPT is an artificial intelligence chatbot capable of having conversations with people and generating unique, human-like text responses. Many individuals use ChatGPT and comparable large language models (LLM) for mental health and emotional support. OpenAI acknowledged that there have been “instances where our 4o model fell short in recognizing signs of delusion or emotional dependency”, and reported that it is working to improve safety. ChatGPT is a chatbot and AI assistant built on large language model technology. It is designed to generate human-like text and can carry out a wide variety of tasks. It can also be fine-tuned for specific use cases such as legal documents or medical records, where the model is trained on domain-specific data.
- This tool allows a user to customize ChatGPT’s behavior for a specific use case.
- OpenAI has already gotten a glimpse of this future through its o1 model, and the results have been mixed.
- Your prompts (on Free, Plus and Pro plans) may be used to train the model unless you opt out in settings.
- OpenAI announced that it is letting users buy goods directly in ChatGPT through a feature called Instant Checkout.
- Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs.
- The language models used in ChatGPT are specifically optimized for dialogue and were trained using reinforcement learning from human feedback (RLHF).

In January 2023, the International Conference on Machine Learning banned any undocumented use of ChatGPT or other large language models to generate any text in submitted papers. Some, including Nature and JAMA Network, “require that authors disclose the use of text-generating tools and ban listing a large language model (LLM) such as ChatGPT as a co-author”. As of July 2025, Science expects authors to release in full how AI-generated content is used and made in their work. In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks). The laborers were exposed to toxic and traumatic content; one worker described the assignment as “torture”.
