ChatGPT’s training data includes software manual pages, information about internet phenomena such as bulletin board systems, multiple programming languages, and the text of Wikipedia. OpenAI collects data from ChatGPT users to further train and fine-tune its services. These labels were used to train a model to detect such content in the future. These rankings were used to create “reward models” that were used to fine-tune the model further by using several iterations of proximal policy optimization.
ChatGPT can find more up-to-date information by searching the web, but this doesn’t ensure that responses are accurate, as it may access unreliable or misleading websites. ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events. 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. A 2025 Sentio University survey of 499 LLM users with self-reported mental health conditions found that 96.2% use ChatGPT, with 48.7% using it specifically for mental health support or therapy-related purposes.

This tool allows a user to customize ChatGPT’s behavior for a specific use case. ChatGPT’s Mandarin Chinese abilities were lauded, but the ability of the AI to produce content in Mandarin Chinese in a Taiwanese accent was found to be “less than ideal” due to differences between mainland Mandarin Chinese and Taiwanese Mandarin. None of the tested services were a perfect replacement for a fluent human translator. For more common languages, AI translators like ChatGPT did better than Google Translate, while for “niche” languages (Amharic and Tagalog), Google Translate performed better.
Training
These models are trained on vast amounts of text data, which allows them to understand language patterns, context, and meaning. 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 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. This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT. 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. … 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.
Across devices, your chat history is usually saved, so you can return to past conversations anytime. Some versions let you upload images to ask questions about what’s shown, making it very flexible.
