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.

- 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.
- In June 2023, hundreds of people attended a “ChatGPT-powered church service” at St. Paul’s Church in Fürth, Germany.
- It is designed to generate human-like text and can carry out a wide variety of tasks.
- 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.
- ChatGPT is an artificial intelligence chatbot capable of having conversations with people and generating unique, human-like text responses.

Addition of E-Commerce Features (April
- {
- In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations.
- In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks).
- Beyond text, ChatGPT can generate original images and videos through its integrated tools.
- This often leads to what experts call “hallucinations,” where the output generated is stylistically correct, but factually wrong.
- In late March 2023, the Italian data protection authority banned ChatGPT in Italy and opened an investigation.
- ChatGPT relies on large language models (LLMs), enabling it to understand your questions and provide human-like responses.

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 Romibet to users who pay for the Plus, Team or Enterprise plan.
How to use ChatGPT for work
The language models used in 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.
Release of Instant Checkout Feature (September
- {
- Robin Bauwens, an assistant professor at Tilburg University, found that a ChatGPT-generated peer review report on his article mentioned nonexistent studies.
- OpenAI announces the ChatGPT Pro plan, a new premium plan for ChatGPT users to access even more features.
- As of July 2025, Science expects authors to release in full how AI-generated content is used and made in their work.
- While users cannot checkout inside ChatGPT, they are redirected to the merchant’s website when they click on the link.
- 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.
- I’ve covered the models and modes above, but here’s a reminder of all the core features (as of October 2025).
