<h2>为什么这么快</h2>
<ul>
<li><strong>DFlash2 投机解码</strong>：每步前瞻 7 个 draft token，高命中率，单流大幅提速。</li>
<li><strong>170HX 专用内核调优</strong>：split-KV verify kernel 用 64-token KV tile（GA100 163KB 共享内存），长上下文 +17~25%。</li>
<li><strong>GA100 稳定修复</strong>：Marlin 重排 + 内存分配器调参，规避 Xid 31，长时间稳定。</li>
<li><strong>256K 超长上下文</strong>：64GB 显存几乎全给 KV，单卡即可容纳 25 万+ token 的文档/代码库。</li>
