The "premium request" billing model where you pay per invocation and not for usage is very obviously not a sustainable approach and creates skewed incentives (e.g. for microsoft to degrade response quality), especially with the shift towards longer running agentic sessions as opposed to simple oneshot chat questions, which the system was presumably designed for. Its just a very obvious fundamental incompatibility and the system is in increasing need of replacement. Usage linked (pay per token) is probably the way to go, as is industry standard.

Paying per token also encouragages reduced quality only now you pay. If they can subtbtly degrade quality or even probability of 1shot solutions, they get you paying for more tokens. Under current economic models and incentive structures, enshitification is inevitable, since we're optimizing for it long term.
