Capacity, Not Format: Rethinking Structured Reasoning Failures
Researchers found that structured output formats like JSON degrade AI model performance not because of formatting itself, but because of insufficient model capacity. Models with adequate computational headroom handle JSON constraints without accuracy loss, while smaller models operating near their limits suffer 28-36 percentage point drops, a penalty that can be partially recovered by reasoning first and formatting afterward.
