If that's the case then these models are failing extremely hard. 7% win rate against human written AIs that they should be copying from memory? A copy paste command should do 50%!
All of the above, to the extent that they can be measured from a simple to verify end condition (stats, win rates, etc). Adaptability, ability to understand and progress on a task, and so on.
The customer may not care what the internal contributions are to such a measure. Instead it represents the customers’ overall values in some way.
Worth digging into the protocol and see what went wrong.
