DSpark: Confidence Scheduled Speculative Decoding with Semi Autoregressive Generation

DSpark 是 DeepSeek 把并行 drafter 推向生产 serving 的一套完整方案：用 DFlash 式 parallel backbone 先一次生成长候选块，再用低秩 Markov head 注入块内局部自回归依赖，随后用 calibrated confidence head 和硬件感知 prefix scheduler 按请求与负载动态裁剪 target verification 长度。离线 Qwen3 / G...

Conditional Memory via Scalable Lookup: A New Axis of Sparsity for Large Language Models

Engram 把大模型稀疏性从 MoE (Mixture of Experts，混合专家，用条件计算扩大 total 参数并控制 active compute) 扩展到 conditional memory：用 hashed N gram lookup 存静态局部模式，用 context aware gate 决定是否把查到的记忆注入 hidden state；在 iso parameter / iso FLOPs 的 27B MoE...
