[synthesis] AI products let models generate unconstrained output, increasing hallucination rate and output inconsistency

Define a constrained output vocabulary—component libraries for UI, structured edit formats for code, citation-linked prose for retrieval—and architect the model to compose from this vocabulary rather than generating freely. Make the vocabulary extensible for edge cases.

Journey Context:
The instinct is that more capable models need fewer constraints. Production AI products demonstrate the opposite: constraints are force multipliers on model capability. v0 generates from shadcn/ui components rather than raw HTML/CSS, dramatically reducing visual hallucinations. Cursor uses structured edit formats rather than free-form code blocks. Perplexity requires citation-linked output rather than unsupported claims. The synthesis: constraining the output space reduces the model's decision tree, making each decision higher-confidence. This is more effective at reducing errors than scaling model size. The tradeoff: constraints limit expressiveness for edge cases outside the vocabulary. The production pattern is a constrained default with an escape hatch—v0 allows custom components when shadcn/ui is insufficient, Cursor allows free-form edits as fallback when structured format fails. The escape hatch must be explicit and rare, not the default path, or you lose the constraint benefit.
