Qwen3.8-27B-DSpark

RadixArk · Qwen3.8-27B-DSpark

A DSpark speculative-decoding draft model for Qwen3.8-27B target models, trained with SpecForge and served with SGLang. The checkpoint has been evaluated with both RadixArk/Qwen3.8-27B-NVFP4 and Qwen/Qwen3.8-27B-FP8 targets. The acceptance-length evaluation below uses the NVFP4 target. The throughput evaluation uses the FP8 target. - Draft parameters: 1,857,358,337 (1.86B) - Draft weight dtype: BF16 - Hidden size: 5,120 - Transformer layers: five full-attention layers - Attention: GQA with 32 query heads and eight key/value heads - Target auxiliary feature layers: 5, 19, 33, 47, 61 - Markov head: VanillaMarkov, rank 256 - Training target width: 16 future positions - Serving gamma: seven draft proposals - Target verification width: eight tokens, including the target bonus token - Maximum position embeddings: 262,144
