+                        
+            The goal is to create a chess-playing language model with **under 1 million parameters**, which is roughly the number of neurons in a honey bee's brain.
+            At this scale, efficiency and clever architecture choices are key! We are not targetting superhuman performance, but rather exploring how well small models can learn the rules of chess, the goal being (only) to play **legal moves**.
             
             1. **Train your model** using the [Chess Challenge Template](https://github.com/nathanael-fijalkow/ChessChallengeTemplate)
