Not if you optimize the tokens used. This is what DeepMyst actually do, one of the things we offer is token optimization where we can reduce up to 80% of the context so even if you use twice the optimized context you will end up with 60% less tokens.
Note that this functionality is not yet integrated with Mysti but we are planning to add it in the near future and happy to accelerate.
I think token optimization will help with larger projects, longer context and avoiding compact.
