The instability of the tooling outside of the LLM is what keeps me from building anything on the cloud, because you're attaching your knowledge and work flow to a tool that can both change dramatically based on context, cache, and model changes and can arbitrarily raise prices as "adaptable whales" push the cost up.
Its akin to learning everything about beanie babies in the early 1990's and right when you think you understand the value proposition, suddenly they're all worthless.
