JFK ΔWER compares each quantized build's JFK transcript to this model's66fp16 JFK transcript, so it measures quantization drift rather than absolute recognition accuracy.67**q4_k** is the recommended default — near-reference quality at a fraction of the68footprint.</sub>69 70## 🧠 About FireRedASR2 LLM71 72FireRedASR2-LLM is the Encoder-Adapter-LLM member of **FireRedASR2**, the successor to73FireRedTeam's open-source industrial-grade **FireRedASR** speech-recognition family, released as74part of the **FireRedASR2S** all-in-one ASR system. At 8B+ parameters with an LLM-scale decoder75backbone, it is the bigger and more accurate sibling of the already-available76**firered-aed-l-v2** (FireRedASR2-AED, a 1.1B-parameter attention encoder-decoder reporting773.05%/11.67% avg CER). The FireRedASR2S technical report (arXiv:2603.10420) and the upstream model78card both report **2.89% average Character Error Rate** across four public Mandarin benchmarks79and **11.55% average CER** across 19 public Chinese dialect/accent benchmarks -- outperforming80Doubao-ASR (3.69%/15.39%), Qwen3-ASR (3.76%/11.85%), and Fun-ASR (4.16%/12.76%) on the paper's own81comparison table. These numbers belong to FireRedASR2-LLM and should not be confused with the82smaller firered-aed-l-v2's 3.05%/11.67% figures. The model is bilingual (Mandarin Chinese and83English). This OpenASR pack distributes the q4_k quantization build, repackaged as an `.oasr`84pack that runs natively in the OpenASR runtime -- fully local, no Python at inference time, no85cloud upload.
