Decision models fix a pricing inefficiency: prefill workloads subsidize decode, argues sh_reya

As decision model hype settles, shreya argues decision models address a market inefficiency: workloads differ vastly (prefill-dominating operations, prefix reuse, intelligence needed), yet pricing is typically uniform — your prefill subsidized my decode at great cost. Cheaper, faster prefill-only endpoints now exist.
Context: TypeSafe reframed their model Jev as a "decision model," but shreya argues treating Jev's questions as decisions means using it at the wrong layer of abstraction, hurting reliability.
