# Learn Artificial Intelligence

Artificial intelligence explained in plain English — beginner guides to LLMs, walkthroughs for running AI models locally, and honest tool comparisons.

## Reading this site as an agent

- Every article has a markdown twin at `https://learnaitodayonline.com/<slug>.md`, generated from
  the same source as the HTML rather than scraped from it, so it contains the
  article and none of the site furniture.
- Each one opens with front matter carrying the canonical URL, the publication
  date, a `last_reviewed` date where one exists, and the series the post
  belongs to.
- A full index of every article is at https://learnaitodayonline.com/llms.txt
- A full URL list is at https://learnaitodayonline.com/sitemap-index.xml
- Figures are charts. The caption under each is often the only provenance for
  a number in the post, so it is preserved in the markdown.
