Hey everyone! I just published an open-source, bilingual (EN/ES) guide on the inner workings of Transformers.

If you are interested in the exact math and mechanics behind attention collapse, KV-cache compression, or just want a solid visual step-by-step from scratch, you might find this very useful. It includes reproducible code and connects with my TAF Agent project for practical testing.

Check it out here: [Cómo Atienden los Transformers](https://karlesmarin.github.io/transformers-guide/es/index.html) (Language toggle at the top).

Feedback or PRs on GitHub are super welcome!
