Earlier quoted context omitted.
The Chinchilla paper was called "Training Compute-Optimal Large Language Models", which is exactly on point.
I mean, it would be slightly more accurate if it had been “Compute-Optimal Training of Large Language Models”, since the models so-trained aren’t the thing that is compute-optimal, the training is compute-optimal. But… yeah, its hardly a title chosen for marketing rather than description.

This website has an interesting graph which visualizes this:
> For example, the compute overhead for 75% of the optimal model size is only 2.8%, whereas for half of the optimal model size, the overhead rises to 20%. As we move towards smaller models, we observe an asymptotic trend, and at 25% of the compute-optimal model size, the compute overhead increases rapidly to 188%.
So if you train your model you shouldn't just look at compute-optimal training but try to anticipate how much the model will probably be used for inference, to minimize total compute cost. Basically, the less inference you expect to do with your model, the closer the training should be to Chinchilla-optimality.
