Fixed-price AI app features—not open-ended model experiments

Founders want AI that does a job: classify support tickets, extract fields from uploads, draft scope from a brief—not a science project billed hourly. Lab Twelve scopes AI features as bounded slices: prompt + UI + guardrails + eval hooks, priced from MVP Sprint or AI add-on ranges depending on depth. Models never invent your quote; the pricing engine maps complexity tiers to published numbers. Humans own security, cost controls, and the pass before production.

FAQ

Questions for this build type

How do you price AI complexity?

Number of workflows, structured outputs, and integrations map to Business App, MVP Sprint, or AI add-on bands—all from offers.ts.

Which models do you use?

Provider is scoped per project—typically Anthropic for extraction and chat. You own runtime cost.

Is this AI-native delivery?

Yes for our pipeline. Your product AI is a scoped feature slice, not unlimited generation.
