The company announced a slew of generative AI-powered features to counter OpenAI and Microsoft. In July, OpenAI released ChatGPT agent, an AI agent that can perform multi-step tasks. It is capable of writing software, answering codebase questions, running tests, and proposing pull requests. The languages tested were Polish, French, Korean, Spanish, Arabic, Tagalog, and Amharic. For more common languages, AI translators like ChatGPT did better than Google Translate, while for „niche“ languages (Amharic and Tagalog), Google Translate performed better. None of the tested services were a perfect replacement for a fluent human translator.

- ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance.
- […] It’s also a way to understand the „hallucinations“, or nonsensical answers to factual questions, to which large language models such as ChatGPT are all too prone.
- 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.
- It can generate plausible-sounding but incorrect or nonsensical answers known as hallucinations.
- 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.
- Apart from models, there are modes and tools in ChatGPT that allow you to go beyond basic chatting.

The Pro launch coincided with the release of the o1 model, providing unlimited access to o1 and advanced voice mode. Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs. OpenAI collects data from ChatGPT users to further train and fine-tune its services.
Release of GPT-5 (August
OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations. ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events. This tool allows a user to customize ChatGPT’s behavior for a specific use case.

- 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.
- 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.
- For more common languages, AI translators like ChatGPT did better than Google Translate, while for „niche“ languages (Amharic and Tagalog), Google Translate performed better.
- 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.
- Despite its acclaim, the chatbot has been criticized for its limitations and potential for unethical use.

Model versions
ChatGPT is becoming a default interface for how people interact with AI and even how they get information from the internet. ChatGPT faces ongoing legal challenges related to industry Romibet concerns regarding the ethics and the legality of data sourcing for AI training. „You can create systems that can fool people into thinking that this thing that you’re talking to is human,“ Jaffri tells CNET. That’s one reason why it sometimes „hallucinates“ or generates confident-sounding but incorrect information. It was trained on massive amounts of data from books and the internet — websites, Wikipedia, Reddit threads, news sites and much, much more.

- Recently, OpenAI made ChatGPT’s image generation capabilities free for all users, albeit with a limited number of monthly uses.
- Released in February 2025, GPT-4.5 was described by Altman as a „giant, expensive model“.
- This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT.
- 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.
- ChatGPT faces ongoing legal challenges related to industry concerns regarding the ethics and the legality of data sourcing for AI training.
- The feature is also still exclusive to ChatGPT users who have a Plus, Team, Enterprise or Education plan.

GPT-4.5
Despite this, users may „jailbreak“ ChatGPT with prompt engineering techniques to bypass these restrictions. […] It’s also a way to understand the „hallucinations“, or nonsensical answers to factual questions, to which large language models such as ChatGPT are all too prone. These limitations may be revealed when ChatGPT responds to prompts including descriptors of people. In one instance, ChatGPT generated a rap in which women and scientists of color were asserted to be inferior to white male scientists. GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users.

In June 2023, hundreds of people attended a „ChatGPT-powered church service“ at St. Paul’s Church in Fürth, Germany. Geoffrey Hinton, one of the „fathers of AI“, voiced concerns that future AI systems may surpass human intelligence. 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-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API. Released in February 2025, GPT-4.5 was described by Altman as a „giant, expensive model“. In March 2023, a bug allowed some users to see the titles of other users‘ conversations.
