The most famous product is ChatGPT. It answers questions, writes code, and helps with creative tasks.

How OpenAI’s Technology Works

OpenAI uses deep learning and neural networks. These systems learn from massive amounts of text, images, and videos. For example, ChatGPT was trained on billions of sentences from books, websites, and articles. As a result, it learned grammar, facts, and reasoning patterns.

The training process has three steps:

Collect data – Gather text from the internet.
Train the model – The AI predicts the next word in a sentence.
Fine-tune – Human feedback improves responses.
