Learn AI Today explains artificial intelligence in plain English for adults who use AI tools but never studied computing. Each post answers one question a beginner actually asks, such as why a chatbot invents facts, how much electricity one prompt uses, or what a computer needs to run a model at home.
What the site covers#
The posts fall into five areas. AI Basics explains what language models are and how they learn. AI and Energy looks at the electricity, water and hardware behind AI. Run AI Locally shows how to run free models on your own computer, with a VRAM calculator that works out what a machine can hold. The quantization and watermark guides go further for readers who want the detail.
New posts are paired with a short video on the site's YouTube channel, starting with the episode on why AI makes things up.
How posts are written#
Every figure in a post links to the source it came from, and a figure that cannot be traced is left out. Where sources disagree, the post shows both and says why. Each post carries the date its facts were last reviewed, because much of this field changes from month to month. Where the site runs its own test, as with the 26-question hallucination test, the post says what was tested, on what and when.
The editorial policy sets out the rules in full, including how AI tools are used and how corrections are handled.
