✅ Pourquoi utiliser ChatGPT ?

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 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. […] 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.
This tool allows a user to customize ChatGPT’s behavior for a specific use case. Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs. The paid experience is faster and more accurate than the free tier, turning up better quality responses across a range of queries and topics. The AI chatbot tries its best to avoid explicit, violent or discriminatory content. It can create personalized workout plans, generate business ideas and even act as your therapist.

This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT. As of 2023, there were several pending U.S. lawsuits challenging the use of copyrighted data to train AI models, with defendants arguing that this falls under fair use. Many individuals use ChatGPT and comparable large language models (LLM) for mental health and emotional support.
