Qwen3.6-35B-A3B APEX I-Balanced + Native MTP head(Lynn 推荐 server-grade 本地版)

这是 Qwen3.6-35B-A3B 的 APEX I-Balanced 量化 + MTP head 完整保留版,在 Lynn GB10 Spark 上实测 think-on 长链 75-85 TPS(无 MTP baseline ~66 TPS),适合 24GB+ 显存 / 32GB+ 内存的本地高质量推理。

定位:端侧 35B 主力,质量接近 BF16,MTP 加速 30% 在 thinking 场景

English summary: this is the Qwen3.6-35B-A3B model with APEX adaptive-precision MoE quantization (I-Balanced variant) with the vendor-shipped MTP (Multi-Token Prediction) head preserved for use with llama.cpp --spec-type draft-mtp. Lynn-benchmarked on NVIDIA GB10 Spark (sm_121). Pairs with the lighter Lynn-9B-GGUF-imatrix release for the Lynn 4-quadrant matrix's heavyweight local tier.

为什么选这一档

35B-A3B(35B 总参数 / 3B active expert)是 Qwen 在 2025 端侧推理性价比之王:

  • active 3B params → decode 速度跟 dense 3-4B 接近(GB10 Spark 单流 60+ TPS)
  • total 35B + 256 experts → quality 大幅超越同 active 参数 dense 模型
  • APEX I-Balanced 量化:重要 expert 高精度,边缘 expert 更激进,体积 24GB 适合 32GB+ 内存设备
  • vendor MTP head 保留:llama.cpp --spec-type draft-mtp 自动启用 single-stream speculative decoding,thinking 长链路再 +29%

TPS 实测 / Throughput Benchmarks

NVIDIA GB10 Spark(sm_121), llama.cpp build-cuda-sm121 commit b1-5d44db6, 2026-05-23。Single-stream decode TPS via llama.cpp built-in predicted_per_second timing。

本仓库(APEX-MTP,--spec-type draft-mtp 启用)

Scenario Cap Tokens generated Decode TPS Notes
think-off 短答 1024 628 59.70 typical chat reply(MTP 在短答场景略损耗,见解读)
think-off 中长 2048 1808 61.95 sustained essay
think-on 数学题 4096 2145 84.69 thinking reasoning
think-on 归纳证明 16384 4213 75.53 math proof + Bayesian framing

vs 同硬件 APEX no-MTP 基线

Scenario APEX no-MTP APEX-MTP(本仓库) Δ
think-off 1024 66.42 59.70 -10% ⚠️(MTP overhead > 收益)
think-on 4096 65.78 84.69 +29%
think-on 16K ~65 estimate 75.53 +16%

⚠️ 何时启用 MTP

启用:thinking_enabled=true 长链路 reasoning,coding 长输出,长 prompt → +20-30% TPS。

关闭 (--spec-type none):short chitchat / think-off 短答 / tool-call only → MTP 反而 -10%,因为 high-confidence n-gram 命中率低。

Lynn client v0.80+ 会根据 chat_template_kwargs.enable_thinking flag 自动 toggle。

评测摘要 / Benchmark Summary

Vendor official Qwen3.6-35B-A3B BF16:

  • MMLU 5-shot: 86.40
  • GPQA Diamond thinking-on 32K: ~86 (vendor reports)
  • AIME / Math: 80+

Lynn 内部 Q4_K_M-imatrix 同模型实测(memory reference_qwen36_35b_release_numbers_20260519):

  • MMLU 500 thinking-off: 83.00%
  • GPQA Diamond 198 thinking-off: 50.00%
  • thinking-on 32K 数据更高(待补)

APEX-MTP-I-Balanced quality 跟 Q4_K_M-imatrix 同档(都是 ~Q4 bit-depth),MTP head 只加速,不改 quality。

MTP 验证 / MTP Verification

llama-server 启动 log 出现以下行确认 MTP active:

load_model: creating MTP draft context against the target model
common_speculative_impl_draft_mtp: adding speculative implementation 'draft-mtp'
  n_max=4, n_min=0, p_min=0.00, n_embd=2048, backend_sampling=1
speculative decoding context initialized

n_embd=2048 是 Qwen3.6-35B-A3B active expert hidden size(9B 同 head 是 n_embd=4096)。
