Dev open-sources Qwen-2.5-1B-RLCD with batched inference for 5x faster on-device JSON generation

Developer harshagundal open-sourced Qwen-2.5-1B-RLCD, claiming 5x faster on-device inference for type-safe JSON workloads on an M4 MacBook, with a demo and weights on Hugging Face.

The trick requires no new training: any LLM can batch inference for every JSON key in parallel and generate probability distributions over a set of candidate categories, with further optimization possible. The post was quote-tweeted by @shinboson with a jab that most AI researcher spin-outs are essentially acquihire opportunities whose products and research are "almost all completely worthless."
