I don't want to pay for a service that doesn't deliver.
You can already do this: hire a consultancy to build you a working deliverable for a fixed price. They will be incentivized to prompt their tools well and to avoid tools that are consistently pathological.
Edit: actually they probably will charge even more if they are charlatans
A handful of honest participants like DeepSeek are pay as you go instead of trying to sneakily bill you for usage.
