- The company also partnered with PayPal, one of the largest payment processing services in the world, to let users pay for their shopping directly within ChatGPT.
- Apart from models, there are modes and tools in ChatGPT that allow you to go beyond basic chatting.
- That’s one reason why it sometimes «hallucinates» or generates confident-sounding but incorrect information.
- I’ve covered the models and modes above, but here’s a reminder of all the core features (as of October 2025).
- 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.
- While users cannot checkout inside ChatGPT, they are redirected to the merchant’s website when they click on the link.

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.
Problème #7 : ChatGPT « oublie » les conversations précédentes
GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users. Premium users were originally limited in the number of messages they could send to the new model, but OpenAI increased and eventually removed these limits. In March 2023, OpenAI announced GPT-4, the latest version of its language model. Developed by OpenAI, the AI chatbot became a hugely popular tool almost overnight. 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.
- This tool allows a user to customize ChatGPT’s behavior for a specific use case.
- It can create personalized workout plans, generate business ideas and even act as your therapist.

Frequently Asked Questions
ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance. The fine-tuning process involved supervised learning and reinforcement learning from human feedback (RLHF). In the case of supervised learning, the trainers acted as both the user and the AI assistant. In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations.
🔧 Peut-on personnaliser ChatGPT ?
It currently uses GPT-5, a generative pre-trained transformer (GPT), to generate text, speech, and images in response to user prompts. The quality of its responses often depends on the wording and context of the prompt, which can vary significantly. ChatGPT can be accessed through its web interface at chatgpt.com using almost any browser.

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. ChatGPT is powered by a large language model made up of neural networks trained on a massive amount of information from the internet, including Wikipedia articles NYXBets casino and research papers. Here’s how it works, its use cases, how to access it, its limitations, notable updates and future outlook. In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks).
