That output is there for a reason. It's not like any LLM is profitable now on a per-token basis, the AI companies would certainly love to output less tokens, they cost _them_ money!

The entire hypothesis for doing this is somewhat dubious.

Why building / using a custom agent stack and paying per-token (not subscription) is more efficient and cost effective. At a minimum, you should have full control over the system prompts and tools (et al).
