Qwen3.8-Flash-Next on a single
@NVIDIAAI DGX Spark just got better 🚀
Default recipe 👇
・Fixed a hidden bug that dropped per-layer embeddings: quality loss 1.397 → 1.344, same speed
・Follow-up replies 2x faster (1.66s → 0.81s), after tool calls 3.61s → 2.72s
・~49 tok/s prose, ~62 code (1 stream), up to ~168 tok/s (4 streams)
・Optional bit-exact decoding for evals and debugging
・Speculative depth 6 unlocked, +16% on code
New opt-in lane on vLLM 0.30 (./start-v030.sh) 🌟
・NVIDIA's official weights now fit on one Spark: the 48 GB per-layer table is read by the GPU straight from a file, built once and reused on every reboot
・FP8 KV backport: 801k tokens of context, 3/3 needles at 200k
・Best quality yet: NLL 1.332
・Prefill +10% (2,140 tok/s), follow-ups 0.67s, code +6% at 4 streams
・Trade-off: prose ~25% slower. Use it for agents, keep the default for raw speed
