This repository releases a DSpark draft model for GLM-5.3. It is a speculator, not a standalone LLM: pair it with a GLM-5.3 target (BF16 or FP8) in SGLang or vLLM. Requires a recent SGLang or vLLM build with native DSpark support. This draft is for GLM-5.3 only. --speculative-num-draft-tokens is block size + 1. The draft is bf16 dense. Keep the draft KV cache dtype on auto so it does not inherit the target's FP8 MLA KV cache. - Context-length numbers are the mean of 3 runs (50 prompts, SPEED-Bench low-entropy throughput) - Qualitative numbers are one run on SPEED-Bench categories (80 prompts each) Acceptance length is the per-request mean of completion tokens divided by verification steps.…
