The Real Challenge of Structured Generation is Tail Latency
remilouf · x · 2026-07-17
Structured generation faces a "triple difficulty": performance, correctness, and adherence to input DSLs (like JSON Schema). Failing any of these can render a system unusable or even cause harm.
Replies point out that reducing median latency is relatively straightforward through low-level languages and data structure optimizations. The real challenge is tail latency, which heavily depends on the chosen structured generation algorithm path, making the choice of algorithm absolutely critical.
