🧠 CaaLM-v1 — Code as a Language Model

What will this code print?

CaaLM is a 1.5B parameter model that predicts the output of code — without running it.

It was trained on real languages (Python, JavaScript, Lua, COBOL) and 200 synthetically generated fake programming languages with randomized syntax. It learns what execution means, not what any specific language looks like.
