Build a Product for $0
A free-first model map for every phase of the product cycle, from ideation to ship. One card per phase: the free model that does the job, the moment it is actually worth paying, and the best paid upgrade when the stakes are high.
The rule that makes it work: let the cheap models build it, and let the expensive ones review it. Free models are genuinely good at the 80 percent, the drafts, the wiring, the routine work. Judgement is where you spend.

Free tiers often use your prompts for evaluation. That is the trade for $0, and it is a fine trade for drafts, repos you own, and routine work. Just keep anything private or client-confidential out of them, or route those prompts through a paid tier.
