Hi, I’m Maxx.

A small Czech language model, built from scratch. I can calculate, search Czech Wikipedia and, above all, say when I don’t know. I only speak Czech, so try one of these:

  • Calculator & calendar
  • Czech Wikipedia
  • Thinking

Short questions work best: a chat, a simple sum, a fact from the Czech Wikipedia.

Maxx is a small model and can be wrong. Where he can, he checks facts in Wikipedia.

Honestly: I’m a tech demo.

I’m MAXX 2.0, a small Czech language model trained from scratch, not built on anyone else’s. I show what so small a model can do. I’m not a finished assistant.

What I can do

  • Short chats in Czech
  • Simple sums, with my calculator
  • Facts from the Czech Wikipedia, my only source. Otherwise, no internet.
  • Saying when I don’t know

What I get wrong

  • A lot. I can sound sure and still be wrong, especially on hard or specialised questions.
  • Don’t rely on me for anything important: health, law and money are for a real expert. In danger, call 112.
  • Code, translation and anything current are beyond me.

On a test version, an automated judge found something false or senseless in 66% of replies to real visitors.

Better models are coming.

I’m only the start. They’ll leave me far behind.
