well, I do understand the core motivation, but if the system prompt literally says “I am not budget constrained. Spend tokens liberally, think hardest, be proactive, never be lazy.” and I’m on an open pay-per-token plan on the API, that’s not what I consider optimal behavior, even in a business sense.

Fair, if you’re paying per token (at comparable rates to other customers) I wouldn’t expect this behavior from a competent company.
