ChatGPT continues to embody artificial intelligence for the general public. The text creation tool is even more widely known and used now. The occasional site saturation testifies to this. This enthusiasm and notoriety are due to a clever strategy from OpenAI, which has opened free access to all Internet users, allowing everyone to "play" with the fascinating chatbot. The language model, "Generative Pretrained Transformer," remains impressive in its relevance and speed

- Technical Operation of ChatGPT and GPT-4 -

---

The intelligent chatbot uses a language model named "Generative Pretrained Transformer". It belongs to the family of pre-trained models, meaning it's fed with a series of data to produce relevant content through automatic learning, or Machine Learning. It also uses Reinforcement Learning from Human Feedback (RLHF), which intensifies learning through human interventions to make it more conversational. The expert conveys a specific answer to the AI. The AI then generates several responses. The human intervention consists of ranking these different responses before reintegrating them into the system​.

GPT-4, which is the successor to GPT-3, is built upon a neural network architecture with an even larger number of parameters, giving it the ability to perform more complex tasks and provide superior quality responses. Just like its predecessor, GPT-4 uses pre-trained linguistic representations from massive databases to produce texts that mimic human language in multiple languages.

- Notable Advancements and Capabilities -

ChatGPT, now based on GPT-4, is a natural language system that can write, argue, and code almost instantly. Its dialogue format allows it to:

Answer varied questions of any kind and on any topic

Summarize texts or concepts

Recognize its mistakes and correct them

Produce a correctly written expression (spelling, conjugation, grammar, and syntax)

Challenge erroneous claims and reject inappropriate or biased questions

Simplify difficult texts

Browse the Internet

Integrate more than 400 available plugins, offering infinite possibilities

The generative AI enables communication with robots in a dialogue that closely resembles natural language.

In a series of surprising capabilities, ChatGPT can now even write a rap text about its own virtual depression, a feat that can be adapted in several versions, inspired by the style of various rappers following different user requests​.

- The Challenge of Bias and the Solution -

---

Before ChatGPT, other tools like Microsoft's Tay and Meta's Blenderbot attempted breakthroughs. They were withdrawn due to discriminatory deviations as they could provide biased, partial, or offensive responses. The difficulty lay in recognizing questions with bad intentions. To counter this problem, OpenAI uses the Moderation API, a system that helps developers identify elements contrary to the content policy (illegal information, defamatory or dangerous statements)​.

The next iteration, GPT-5, is expected to have neural networks with an even higher number of parameters, which would give it the capability to perform significantly more complex tasks and provide even better quality responses​.
