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. 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.

• ChatGPT is an artificial intelligence chatbot capable of having conversations with people and generating unique, human-like text responses.

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. Many companies adopted ChatGPT and similar chatbot technologies into their product offers. 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. Robin Bauwens, an assistant professor at Tilburg University, found that a ChatGPT-generated peer review report on his article mentioned nonexistent studies. A 2023 study reported that GPT-4 obtained a better score than 99% of humans on the Torrance Tests Crowngreen casino of Creative Thinking.

Release of Study Mode (July

This update allows ChatGPT to remember details from previous conversations and tailor its future responses accordingly. According to an OpenAI blog post, ChatGPT will build memories on its own over time, though users can also prompt the bot to remember specific details — or forget them. OpenAI initially releases this feature to users who pay for the Plus, Team or Enterprise plan.

How does ChatGPT work?

ChatGPT is a generative artificial intelligence chatbot developed by OpenAI and released in November 2022. It currently uses GPT-5, a generative pre-trained transformer (GPT), to generate text, speech, and images in response to user prompts. 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.

• OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations.
• This update allows ChatGPT to remember details from previous conversations and tailor its future responses accordingly.

{

• 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.

|}

• Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs.

{

• They can explicitly tell ChatGPT to remember aspects of the conversation, and ChatGPT can use these details in future conversations.

|}{

• For example, the new model doubles its context window from 128,000 tokens in GPT-4o to 256,000 tokens in GPT-5.

Most people know that, just because something is on the internet, that doesn’t make it true. 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.
