ChatGPT is a large language model (LLM) — a type of AI trained on enormous amounts of text from the internet, books, and other sources. The training process involved the model making billions of predictions about what word should come next in a sequence, adjusting its internal parameters to get better over time.
The result is a model with approximately 100-175 billion parameters (for GPT-4) that has absorbed statistical patterns across virtually every topic humans write about. When you ask it a question, it generates a response by predicting which words are most likely to follow your prompt, given its training.
This is why it can be confidently wrong — it's generating plausible-sounding text, not looking up facts from a database. When it hallucinates (invents false information), it's producing text that statistically resembles the pattern of correct answers without actually checking facts.
The "GPT" stands for Generative Pre-trained Transformer. "Transformer" is the architecture that enabled the modern AI boom — it processes text in parallel rather than sequentially, making it far more powerful than previous approaches.
Think of it as an extraordinarily sophisticated pattern-matcher and text generator, not a thinking machine that "knows" things the way humans do.

AI image generators like Midjourney, DALL-E, and Stable Diffusion work through a process called diffusion. They start with pure noise (random pixels) and progressively denoise toward an image that matches the text description you provided.
During training, these models were shown millions of image-text pairs from the internet. The model learned the statistical relationship between textual descriptions and visual features. When you type "a Nigerian market at sunset, oil painting style," it uses those learned associations to guide the denoising process toward an image that statistically resembles what that phrase patterns in its training data.
The quality of your output depends heavily on your prompt. Effective image prompts include: subject description, art style (photography, oil painting, digital art), lighting description, camera angle, mood, and technical quality terms (sharp focus, 8K, detailed).
Midjourney is generally considered to produce the most aesthetically polished results and is easiest to use. DALL-E 3 (accessible through ChatGPT Plus) excels at following text instructions precisely. Stable Diffusion is open-source and free but requires more setup and prompt craft.
