Open-sourced Qwen-1B-RLCD runs type-safe JSON inference 5x faster on-device

A developer open-sourced Qwen-2.5-1B-RLCD, demoed on an M4 MacBook with 5x faster on-device inference for type-safe JSON workloads, now on Hugging Face.
The trick: LLMs can batch-infer every JSON key in parallel and produce probabilities over candidate categories — no new training required, and easy to optimize further.
Quoting the post, @swill1ams frames the business angle: run items through a cheap PCD-style custom model that classifies each step (ticket triage, invoice approval, claim flagging) with mathematically accurate confidence, and only escalate low-confidence cases to frontier models — cutting the few-cent-per-call token cost of today's agent workflows.
