It is very unlikely that anyone is going to give you a good advice with so little information about your cost structure. There is great people here who can provide invaluable insights about your costs but they need to have more information.

We use a lot of GPU intensive models and 80% of revenue goes into AWS, doesn't mean that your AWS cost is mostly GPU. It should mean that, but who knows. Tell us how is your AWS infrastructure, what instances do you have, how much do they cost to you, etc. Because with your information about the costs the best advice you can get is to not use AWS neither GPU-intensive ML models.
