Can you have it play more games by giving it less time per turn (~2500 rating is plenty good for an opponent/coach) and playing games concurrently while it waits for human to play?

how much does a game cost in CPU time money?

How do I get the commentary for a game I played? Oh, it's in Analysis page.

It plays chess very well, but the commentary is incoherent and doesn't match the game well -- The attacks described are nonsense and the coordinates are wrong. It seems a little confused about which side is which? It thinks a rook can diagonally attack a bishop, and seems to name squares opposite from their actual name.

That's a good idea. A bigger problem than time-slicing is probably GPU/TPU device ownership issues and GPU/TPU memory usage with multiple games going in parallel. There may be some ways to multiplex it intelligently though.

Costs are difficult to work out - it depends on cloud vs. self-hosting, what kind of TPUs/GPUs, how long you're calculating over.

The advantage that classical/NNUE engines have is that they can more easily spread over distributed frameworks like Fishtest.

Agreed, this looks superficially like commentary on the game, but honestly it doesn't seem more pertinent to the game score than a Markov chain trained on all the commentary would be (presumably this isn't true, and the author started with something like that Markov chain and the current version is way better in terms of some fitness function).

I wonder if there just is not enough training data available. GPT-3 overcomes this by harvesting a ridiculous amount of training data. AlphaZero, and the chess engine here, which is excellent, overcome it by generating their own training data through self play. But that's not applicable to the task of generating commentary.
