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.

• In August 2025, OpenAI released GPT-5, its fastest and smartest model to date, and the current language model for ChatGPT.
• Many individuals use ChatGPT and comparable large language models (LLM) for mental health and emotional support.
• The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code.

• In late March 2023, the Italian data protection authority banned ChatGPT in Italy and opened an investigation.

• 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.

|}{

• This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT.

{
• 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.

|}

• The full capabilities of ChatGPT are still being explored by its millions of users.

{

• ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events.

• OpenAI’s outsourcing partner was Sama, a training-data company based in San Francisco, California.

{

• The laborers were exposed to toxic and traumatic content; one worker described the assignment as “torture”.

• Robin Bauwens, an assistant professor at Tilburg University, found that a ChatGPT-generated peer review report on his article mentioned nonexistent studies.

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 ?

ChatGPT became one of the fastest-growing apps in history, amassing hundreds of millions of users. ChatGPT is the artificial intelligence chatbot that started the whole generative AI revolution. 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.

• The feature is also still exclusive to ChatGPT users who have a Plus, Team, Enterprise or Education plan.

• ChatGPT is a generative artificial intelligence chatbot developed by OpenAI and released in November 2022.

{

• Geoffrey Hinton, one of the “fathers of AI”, voiced concerns that future AI systems may surpass human intelligence.

• For example, the new model doubles its context window from 128,000 tokens in GPT-4o to 256,000 tokens in GPT-5.
• The fine-tuning process involved supervised learning and reinforcement learning from human feedback (RLHF).

Technique 2 : Le Cadre de Prompt AllAboutAI (CRISPE+)

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 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).

Languages

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 NYXBets casino chatgpt.com using almost any browser.

Release of Instant Checkout Feature (September

By January 2023, ChatGPT had become the fastest-growing consumer software application in history, gaining over 100 million users in two months. As of 2025, ChatGPT’s website is among the 5 most-visited websites globally, and has over 800 million active weekly users.

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.
