[synthesis] Why successful AI features become unprofitable and get silently degraded

Design AI products with cost-quality decoupling from day one: implement tiered model routing where simple queries use cheap models and complex queries use expensive ones. Set per-user and per-feature cost budgets with graceful degradation, not hard cutoffs. Track unit economics per feature per user segment, not just aggregate cost. Build cost canaries that alert when a feature's cost-to-revenue ratio crosses a threshold.

Journey Context:
Traditional software has roughly fixed marginal cost per user. AI products have variable marginal cost that scales with usage and complexity. This creates a perverse dynamic: your best, most useful AI feature gets used the most, costs the most, and may become unprofitable. Teams respond by degrading model quality—smaller model, fewer tokens, cheaper provider—which reduces usefulness, which reduces usage, which looks like 'the feature isn't working' rather than 'we made it worse to save money.' This is a death spiral because cost optimization and quality optimization are fundamentally at odds in AI products in a way they aren't in traditional software. The feature appears to fail organically when it was actually suffocated by cost pressure.
