This is basically how you should treat all AI dev. Working around AI model limits for something that will take 3-6 months of work has very little ROI compared to building what works today and just waiting and building what works tomorrow tomorrow.
This is the hard part - especially with larger initiatives, it takes quite a bit of work to evaluate what the current combination of harness + LLM is good at. Running experiments yourself is cumbersome and expensive, public benchmarks are flawed. I wish providers would release at least a set of blessed example trajectories alongside new models.
As it is, we're stuck with "yeah it seems this works well for bootstrapping a Next.js UI"...
This assumes AI model improvements will be predictable, which they won’t.
There are several simultaneous moving targets: the different models available at any point in time, the model complexity/ capability, the model price per token, the number of tokens used by the model for that query, the context size capabilities and prices, and even the evolution of the codebase. You can’t calculate comparative ROIs of model A today or model B next year unless these are far more predictable than they currently are.
