The same model will not get better by having more processing power or time. However, that's not the full story. Larger models generally perform better than smaller models (this is a generalization, but a good enough one for now). The problem is that larger models are also slower. This ends up being a balancing act for model developers. They could get better results but it may end up being a worse user experience. Models size can also limit where the model can be deployed.
