同族不同尺寸 LLM 的 KV cache 之间存在大量线性结构:用 500 条 FineWeb-Edu 序列、按 target 的每个 (layer, head) 做闭式 ridge,就能让接收方直接从发送方的 KV 解码、完全跳过 prefill。六对中四对保住 target 自身 73–98% 精度、比 re-prefill 快 2.7–25$\times$;另两对崩到 42–44%。成败由残差落在 attention 敏感子空间的位置决定,而非残差大小。 ---
Hybrid (Attention+SSM) LLMs break prefix caching because in-place SSM state updates forbid prefix roll-back — only exact-match hits work, so naive checkpointing floods the cache with huge, rarely-reused entries. Marconi admits SSM states judiciously (≤2 per sequence, chosen by a reuse taxonomy) and
2.8T 参数 / 104B 激活的原生多模态 MoE,1M 上下文。三根支柱:3:1 的 KDA–Gated MLA 混合注意力(序列维)、Attention Residuals(深度维)、16-of-896 的 Stable LatentMoE(宽度维)。宣称对 Kimi K2 有 ~2.5× scaling 效率增益。多处架构改动的直接动机是解锁 kernel 路径而非模型质量。 ---
A sequence-transduction model built *entirely* from attention, discarding recurrence and convolution. Stacked multi-head self-attention plus position-wise FFNs give $O(1)$ path length and full intra-example parallelism, reaching 28.4 BLEU (EN-DE) / 41.8 BLEU (EN-FR) at a fraction of prior training c
A general-purpose fine-tuning recipe that couples a pre-trained DPR dense retriever (non-parametric memory: a fixed 21M-passage Wikipedia index) with a pre-trained BART seq2seq generator (parametric memory), treating the retrieved document as a latent variable marginalized end-to-end. Sets SotA on o
Scaling a plain GPT-2-style autoregressive decoder to 175B parameters makes task-agnostic **in-context learning** work: with no gradient updates, GPT-3 learns tasks purely from prompt demonstrations, sometimes matching fine-tuned SOTA. The load-bearing finding is that the zero→few-shot gap *widens*
Autoregressive generation scales terribly on multi-step grade-school math. Instead of a bigger generator, train a separate *verifier* that scores 100 sampled solutions and return the best. On the new GSM8K benchmark, 6B verification ≈ finetuned 175B — a ~30× parameter saving, scaling better with dat
把"思考"当成一种不改变环境的语言动作,塞进 agent 的动作空间 $\hat{A}=A\cup L$,让冻结的 PaLM-540B 用少样本交替生成 Thought/Action/Observation。推理指导取信息、取信息纠正推理,QA 上消灭幻觉,决策任务上 1–2 shot 反超训了 10³–10⁵ 条轨迹的 IL/RL。
一个 6.7B 的 GPT-J 用自监督方式给普通文本自动插入 API 调用,只保留"能降低后续 token 预测损失"的调用,再在增广数据上微调。学会自己决定何时/调用哪个工具后,零样本超越 25× 更大的 GPT-3,且不损失语言建模能力。
Reflexion turns a sparse reward (binary/scalar) into a *verbal* self-reflection stored in an episodic memory buffer, so an LLM agent improves across trials without any weight update. Policy is $\theta = \{M_a, mem\}$. Hits 91% HumanEval pass@1, +22% AlfWorld, +20% HotPotQA — but only on strong backb
AutoGen 把复杂 LLM 应用统一抽象为「多个可对话 agent 相互聊天」。核心是两件事:可定制的 conversable agent(LLM/人/工具任意组合)+ conversation programming(用自然语言与代码融合来编排 computation 与 control flow)。六个应用(数学、RAG、ALFWorld、多 agent 编码、动态群聊、对话象棋)证明开箱即用即可匹敌/超过商业与 SOTA 基线,同时大幅减少代码量。
自回归 LLM 会把大量注意力"倾倒"到最初几个 token(注意力汇),因为 SoftMax 强制分母求和为 1。窗口注意力一旦驱逐这几个初始 token 就崩溃。StreamingLLM 保留 4 个初始 token 的 KV + 滑动窗口 KV,无需微调即可稳定处理 4M+ token,比重算基线快 22.2×。 ---
A benchmark of 2294 real GitHub issue→PR tasks across 12 Python repos: given an issue and a full codebase, the model must emit a patch that passes the PR's real tests. Even with an oracle retriever handing over the exact files to edit, the best model resolves only 4.8% — localization and long-contex
当被复用的长上下文 KV cache 存在远端存储、需经普通云网络(单位数 Gbps)取回时,取回延迟可与重算 prefill 相当甚至更久。CacheGen 用改造过的视频编码流水线把 KV cache 编码成紧凑比特流(size 降 3.5–4.3×,TTFT 降 3.2–3.7×),并按带宽逐块自适应流式传输以守住 SLO。
LLM inference has two phases with opposite hardware profiles: prompt (compute-bound) and token generation (memory-bound, power-insensitive). Splitwise runs them on separate, phase-matched machine pools, transferring the KV-cache over InfiniBand with layer-wise async overlap. Result: up to 1.4× throu
A co-designed frontend DSL + serving runtime for multi-call LLM programs. The runtime keeps finished KV caches in a radix tree with LRU eviction and schedules requests longest-shared-prefix-first (provably DFS-optimal), and compresses constrained-decoding FSMs so single-path token runs decode in one
DistServe splits LLM inference so prefill and decoding run on separate GPU pools, killing phase interference and letting each phase pick its own parallelism. A goodput-optimal placement search plus NVLINK-affinity KV transfer yields up to 7.4× higher request rate or 12.6× tighter SLO at >90% attainm
在线 LLM serving 中,prefill(计算受限)与 decode(内存受限)交织导致吞吐-延迟二选一。Sarathi-Serve 用 chunked-prefill + stall-free batching:把长 prefill 切成受 token budget 约束的小块,piggyback 到 decode 批次而不打断 decode。Mistral-7B 提升 2.6×、Falcon-180B 提升 6.9× serving capacity。
Multi-turn LLM serving discards each session's KV cache when idle, then recomputes it on the next turn — up to 99% of prefill cost is this wasted recompute. CachedAttention keeps KV in a tiered DRAM+SSD store (AttentionStore), overlaps load/save with compute, prefetches/evicts using the scheduler's
Public LLM APIs are request-level, so the serving cluster is blind to how an app's many LLM calls connect. Parrot's **Semantic Variable** annotates prompt regions (task/input/output) and doubles as an inter-request data pipe, letting the service recover a request DAG + prompt structure and jointly d
A dense 405B Transformer trained on 15.6T tokens at $3.8\times10^{25}$ FLOPs, deliberately choosing a boring architecture + SFT/rejection-sampling/DPO alignment over MoE + RL. The bet: quality comes from data curation, scale, and complexity management, not architectural novelty.
Qwen3 fuses a reasoning model and a chat model into **one** checkpoint via a 4-stage post-training pipeline (Long-CoT cold start → Reasoning RL → Thinking-Mode Fusion → General RL), adds a user-controllable **thinking budget**, and builds its 6 small models by **on-policy distillation** that beats R
LMCache is an out-of-GPU KV cache layer that extracts KV cache from vLLM/SGLang and stores/shares it across a storage hierarchy (CPU, disk, Redis, remote, network) for two use cases: cross-query prefix reuse and prefill–decode disaggregation. Its core trick is moving KV at a large **chunk** granular
Agentic programs alternate between busy phases (bursts of short tool calls) and idle phases (blocked on a long tool call). MORI ("Memory Offloader with Relative Idleness") reconstructs each live program's *idleness* $\iota$ from step timing, ranks all programs on a **continuous** spectrum, keeps the
RAPTOR builds a bottom-up tree over a corpus by recursively embedding, soft-clustering (UMAP+GMM), and LLM-summarizing chunks, so retrieval can pull context at multiple abstraction levels. Coupled with GPT-4 it lifts QuALITY from 62.3% → 82.6% absolute.
StruQ converts a **base** LLM into a defended one by (a) encoding prompt vs data into two channels with **reserved-token delimiters** the user cannot forge, and (b) **structured instruction tuning**: augment SFT data with attacked samples whose target output ignores the injected instruction. Drives
LLM 缺少指令/数据的显式隔离。本文给出隔离度的**形式化定义**(把探针 $x$ 放进指令位 vs 数据位,比较输出分布差异)、一个只靠"惊讶见证词"子串检测、无需 logits 的**黑盒经验代理指标** $\mathrm{sep}(g)$,以及 9160 条评测数据集 **SEP**。9 个主流模型全部隔离度低(13.3%–73.2%),且**模型越大隔离越差**;提示工程/优化/微调都无法同时兼得高隔离与高效用。
给 LLM 建立"指令特权等级"(System > User > Tool/第三方),并用两种合成数据原语(对齐指令做 context synthesis、非对齐指令做 context ignorance)微调 GPT-3.5 Turbo,使其在冲突时服从高特权指令。鲁棒性最高提升 63%,并泛化到训练中未见的越狱/密码提取攻击(+34%)。 ---
LLMs treat every input token equally, so a lower-priority user/data token can override a system instruction. ISE adds a tiny learned $H{\times}D$ segment-embedding table (system/user/data/output = 0/1/2/3), summed onto token embeddings before self-attention, and trained during SFT. Result: +15.75% a
MoE decode is memory-bound at moderate batch sizes, so latency is linear in the number of *unique* activated experts $T$ (the union over the batch). OEA re-routes tokens at inference (no retraining): guarantee each token a top-$n_i$ baseline, then let tokens piggyback extra experts already loaded fo
In memory-bound MoE decode, GPU runtime is set by the number of *activated expert replicas* (weight loads), not tokens. Token-balancing load balancers (EPLB) inadvertently inflate activated experts and hurt decode. METRO instead minimizes max activated experts/GPU via a lock-guarded greedy kernel +
MPK auto-compiles a multi-GPU PyTorch inference program into a single persistent mega-kernel via an SM-level task/event graph (tGraph) plus an in-kernel worker/scheduler runtime, enabling cross-task pipelining and fine-grained compute-comm overlap. Up to 1.7× lower latency vs SGLang/vLLM.
Constrained decoding masks+renormalizes each step; when the base model puts little mass on schema tokens, this is a reverse-KL projection with a large "projection tax" that steers toward valid-but-wrong outputs. DCCD first generates an unconstrained draft, then constrains conditioned on it — raising
Forcing an 8B model (Qwen3-8B) to do structured self-reflection via `Outlines` FSM-constrained decoding does **not** improve self-correction — accuracy drops 50.0%→38.0% and 96/100 diagnoses collapse to `FORMATTING_MISMATCH`, trapping 58 samples in death loops. This "structure snowballing" is the al
Decouples memory-management from reasoning: a small RL-trained ContextCurator (Qwen2.5-7B) rewrites working memory each turn for a *frozen* frontier TaskExecutor. On WebArena, Gemini-3.0-flash goes 36.4%→41.2% SR with −8.8% tokens; on DeepSearch, ~8× fewer tokens at higher SR. A 7B curator ≈ GPT-4o.
一个统一的世界-动作模型,用 UniDiffuser + 三流 MoT 把视频与动作放进同一生成框架,5 种推理模式共享一套权重。靠相对末端执行器动作表示做跨本体迁移(50–100 条轨迹),并以推理栈实现 54.4× 加速 / 11 Hz。RoboTwin 2.0 达 95.8%/96.1%,WorldArena EWMScore 63.77 第一。
Ψ-RAG replaces RAPTOR's $k$-means/GMM cluster tree with an AHC-style "merging and collapse" abstract tree (no distribution prior), adds an R&A agent with query reorganization for multi-hop causality, and fuses a BM25 sparse index to fix coarse abstraction. First Tree-RAG to beat SOTA Graph-RAG: +25.
首个专为**交互式世界模型**设计的基准:用一个"动作生成框架"把文本/one-hot/相机内外参三类异构控制统一编码为 $(D,T,R,V)$ 四元组(81 个基础动作),配 330k 视频语料 + 4,900 任务 + 9 个可微指标,评测 14 个模型,揭示"生成质量 vs 可控性"权衡(Spearman $r_s=0.8053$ 与人类偏好对齐)。
首个系统梳理 World Action Model (WAM) 的综述:把"预测未来状态 + 生成动作"统一为联合分布 $p(o',a\mid o,l)$,将现有方法切成 Cascaded(先预测后解动作)与 Joint(联合预测)两大范式,并系统整理数据生态与评测协议,指出评测严重解耦、缺乏因果一致性指标。 ---
In xPyD MoE serving, decode latency is set by the *union* of distinct experts a batch loads from HBM, not by request count. ELDR reads each request's prefill expert activations into a compact signature, clusters them offline with balanced K-means (one centroid per decoder), and routes online within
Treat an LLM agent's file-system memory as a *trainable skill*, not a fixed module. Two meta-LLM outer loops — one revising the memory scaffold (code/prompts/schema), one LoRA-training a memory specialist on the agent's own good decisions — lift a frozen 32B agent 2×–4× on Crafter/MiniHack/NetHack,
A separate memory agent runs beside an unmodified action agent, maintaining a structured memory bank every N steps and deciding *whether* to inject a grounded reminder or stay silent. Fixes "behavioral state decay". +8.3 pp Terminal-Bench, +6.8 pp τ² (Sonnet 4.5); learnable on Qwen3.5-27B.
Context engineering (offload/summarize/truncate/isolate) keeps agent contexts short but each rewrite invalidates the KV cache and forces a re-prefill, spiking TTFT. SmoothAgent observes these rewrites are *segment-decomposable* — each prefix segment transforms independently of future tokens — so it
用 Mixture-of-Transformers 把「动作→3D世界预测」(前向模型)与「3D世界→动作」(逆动力学)通过双向注意力耦合进同一隐空间,再加上 3D-grounded 的 2D 视觉想象。仅 6k 小时(其中真机 1k 小时)预训练即达 RoboTwin2.0 hard 93% SR、真机较基线 +20%。
Agentic LLM serving shifts the goal to cluster TPS and makes KV$ reuse dominate (>80% vs 54–62% chat). Cache-aware schedulers overload a few instances by pinning whole sessions. SMetric balances only each session's *first* request and routes follow-ups cache-aware, gaining 10–16% TPS (colocation) an
AgentSM makes a Text-to-SQL agent reuse *structured* prior exploration traces (built offline from synthetic questions) and merges frequently co-occurring tool calls into composite tools. This cuts trajectory length ~25% and lifts accuracy to a SOTA 44.8% on Spider 2.0 Lite — without a heavy reasonin
把预训练视频扩散模型 (Cosmos-Predict2-2B) 通过**单阶段微调、零架构改动**变成机器人策略:动作、未来状态、状态价值都编码成"注入的 latent frame",共享同一套视频扩散去噪目标。既做直接策略 (LIBERO 98.5% / RoboCasa 67.1% / ALOHA 93.6% SOTA),又能用 rollout 数据精炼 world model + value 做 best-of-N 规划,再涨 +12.5 分。
LingBot-VA 把机器人操控重构成"先预测未来视频、再逆动力学解码动作"的自回归扩散世界模型:视频/动作 token 交织成单一因果序列,用双流 MoT(视频流从 Wan2.2-5B 初始化, 动作流窄 4×)联合训练,靠 KV-cache 维持长程记忆、部分去噪+异步执行做实时闭环。RoboTwin 2.0 92.9%/91.6%,LIBERO 98.5%,50 演示即可适配。 ---
DreamZero is a 14B autoregressive video-diffusion backbone fine-tuned to *jointly* denoise future frames and actions.

World Action Models entangle two things: a video-prediction training objective and test-time future video synthesis. Fast-WAM keeps video co-training but replaces future denoising with a single-pass world encoder for actions. Result: on-par accuracy, 190 ms latency (>4× faster), and the training obj
One shared Wan video-diffusion backbone exposes two interfaces: a Video Action Model (VAM, 5.5B) that jointly predicts future latents + action chunks, and an Action-Conditioned Video Simulator (ACVS) that scores candidate actions.

综述界定"交互式视频世界模型"= 闭环、逐帧动作条件、多轮交互的视频生成,并把整个领域拆成三个技术瓶颈——动作可控性、长程一致性与记忆、实时响应性——逐一梳理主流做法(动作注入四法、记忆/Forcing/显式 3D 三条一致性路线、蒸馏与缓存加速),最后横向对比四大应用(开放世界、游戏引擎、具身、自动驾驶)的 benchmark 与指标。
LaWAM gives a VLA policy explicit dynamics foresight without generating future pixels: it keeps the *forward decoder* of a latent action model (usually thrown away) as a Latent World Model (LaWM) that expands a policy-predicted latent action into one latent visual subgoal in a single forward pass.

一套固定超参数的 model-based RL 智能体,通过 RSSM 世界模型 + 想象空间 actor-critic,在 8 大类 150+ 任务上击败各自领域专用算法,并首次无人类数据、无课程从零采到 Minecraft 钻石。核心是一组量纲无关的鲁棒性技巧(symlog、symexp twohot、KL free bits、百分位回报归一化)。
Halo treats a batch of same-template agentic workflows as one consolidated query-plan DAG, then solves query optimization + scheduling as a single GPU-worker-placement problem (beam search over a prefill/decode + cache-reuse cost model). Runtime adds adaptive batching, prefix-cache sharing, and on-t
在多模型 agent 工作流里,同一段共享上下文被每个专用模型各跑一遍 prefill 并各存一份 KV。PrefillShare 把模型拆成「冻结的共享 prefill 模块 + 各任务专用 decode 模块」,只用 cache-conditioned 微调训 decode 去读 base 的 KV,从而一次 prefill、一份 KV 跨模型复用。精度追平全量微调,p95 延迟降 4.5×、吞吐升 3.9×。 ---
Agentic inference stacks glue a stateless LLM engine (vLLM) to a stateless tool orchestrator (Kubernetes), scheduling each LLM/tool call independently — causing KV-cache thrashing, cross-node memory imbalance, and leaked tool resources. ThunderAgent makes the whole multi-turn workflow a first-class
Agent memory turns every generation step into a frequent, interleaved ANN search/insert against a growing vector index; at scale this consumes 82%+ of runtime. Pancake attacks this with three coordinated tiers — locality-aware multi-level cache (FSM-driven), a hybrid graph unifying multi-agent coars
Orla is a serving layer that sits *between* agent-orchestration frameworks and LLM inference engines. It models an agentic task as a DAG of stages and adds three workflow-aware mechanisms — a stage mapper (per-stage model/backend routing), a workflow orchestrator (two-level scheduling), and a memory
Helium serves batch agentic workflows by modeling them as query-plan DAGs with LLM calls as first-class operators, then applies proactive KV/prompt caching + cost-based cache-aware scheduling over a templated radix tree. Up to 1.56× over KVFlow, 0.9% avg gap to MILP optimum, exact semantics. **Agen
Middleware atop vLLM that serves multi-agent workflows on a *mix* of LLM sizes/families. It couples a semantic router (per-model success confidence), a CPU QRF that predicts a workflow's *total remaining* output tokens, and an in-flight-token load monitor to pick the strongest model within a latency
Multi-LoRA agent serving breaks prefix caching: distinct adapters make identical-text KV caches diverge, so each agent keeps a redundant full cache and GPU memory saturates linearly. ForkKV physically splits KV into a shared base cache ($xW$) + tiny per-agent residual ($xA_i$), forks it with OS-styl
Agentic workflows have wildly unpredictable end-to-end latency, but each LLM's *share* of total execution time is stable. Scepsy exploits this: it traces workflows framework-agnostically, folds them into an "Aggregate LLM Pipeline" (a cheap throughput/latency predictor), then jointly searches fracti
Agent tasks fire 10–100 chained LLM calls, but request-level GPU schedulers discard each session's KV cache across tool calls, inflating latency 3–8×. SAGA makes the whole agent workflow the schedulable unit: workflow-aware eviction (within 1.31× of Bélády), session-affinity batching with work steal
Dynamic multi-agent workflows (retry loops, runtime branches) break both LRU (temporal locality) and KVFlow (static DAG) for KV-cache management. PBKV predicts the next $K$ agent invocations with a tiny GraphSAGE model, scores each cache node by cross-workflow expected reuse, then evicts retired-cac
SPECTRE reuses idle tail-model services as remote speculative drafters for busy large models, and adaptively switches between *parallel* (draft overlaps verify) and *ordinary* (draft waits) modes using a throughput-derived rollback threshold $r^*$. Up to 2.28× over AR, +66% over the best SD baseline
Agentic requests are multi-call DAGs revealed online; users feel end-to-end workflow latency, not per-call latency. HexAGenT maintains a per-workflow standalone horizon $H_w(t)$, ranks ready calls by projected scaled-SLO risk, and jointly picks prefill/decode placement + queue priority on heterogene
Agentic serving is irregular at the turn but stable at the conversation: one compute-bound turn-1 prefill + a long memory-bound tail. Scheduling the conversation (not the turn) replaces unobservable decode-cost prediction with two observable signals — turn-1 input length and per-decoder KV occupancy
Multi-turn agents blow up KV memory/bandwidth far more than compute. IntentKV keeps the base LLM frozen and prunes KV by (a) scoring history against a session-level QueryMemory of accumulated intent + a zero-init residual head, and (b) evicting via slot-map redirection to a dead slot instead of comp
Serving LLM multi-agent workflows under tight GPU budgets breaks because each stage's decode length and KV footprint are unknown, model demand is long-tailed, and clusters differ in readiness vs latency. Maestro predicts per-stage output length and KV need (tool-intent classifier + role-aware regres
Coding agents are long-running, closed-loop LLM sessions (median 36 min, ~20× more tool-driven than user-driven turns) that reuse large, growing prefixes.

ABot-M0.5 是一个面向移动操作 (mobile manipulation) 的 World Action Model。核心论点:移动操作失败不是模型规模不够,而是三处结构性错位——时间粒度、动作空间、训练-推理一致性。三个对应机制:帧级 latent action 桥接粗视频与细控制;dual-level MoT 解耦 mobility/manipulation 子空间;Dream Forcing 用自梦视频训练逆动力学。RoboCasa365 平均 40.4%(SOTA)。
Kairos is a 4B native world-action model that trains a video-diffusion backbone from scratch on a passive→human→robot data curriculum, replaces quadratic attention with a hybrid SWA+DSWA+GLA design (proven to bound long-horizon error via a contractive gated-delta memory), and co-designs distillation
KVCOMM针对多智能体LLM通信中的重复prefill,提出无需训练的在线KV复用:先做RoPE位置对齐,再用anchor池估计跨上下文偏移并增量更新。论文在MMLU/GSM8K/HumanEval上保持接近原始精度,同时把多agent首token延迟显著压缩(最高约7.8x)。
TokenCake targets LLM multi-agent serving where tool calls create long KV-cache idle windows and graph-critical agents compete for scarce GPU blocks. It co-designs an event-driven Temporal Scheduler (opportunistic offload + predictive upload) and an agent-aware Spatial Scheduler (dynamic reserved/sh
用“KV 缓存编辑指令”把 agent 的消息改写变成服务端可执行的 span splice;在 MLA 下用闭式 RoPE $\delta$-rotation 让编辑后缓存仍位置正确,从而提升 replay cache hit(+11.2pp)并在部分并发下显著降延迟(峰值 -241ms)。
来自 ALIYUN 通义生产集群一周真实 trace 的首个系统性 KV$ 复用画像:理想命中率仅 62%/54%(远低于合成负载的 >80%),单轮请求贡献 to-B 负载 97% 的命中,KV$ 寿命极短(to-B P99=97s,90% 块 0.3s 内不再复用),因此中等容量缓存即够用。据此把 GDFS 改造成按类别复用概率排序的 workload-aware 淘汰策略,命中率 +1.5–3.9%、QTTFT 降 28.3–41.9%。
FlowKV 通过 KV cache tensor 形状变换 + segment-based 连续分配 + 双向段对齐,将 PD 分离推理中 NCCL KV 传输延迟降低 96%(23,469 次 kernel 调用 → 1 次),配合 Load-Aware Scheduler 实现异构 GPU 部署下 15–49% 端到端加速。 ---
KVCache offloading 系统的 CPU 三大瓶颈(细粒度缓存管理、PCIe 带宽浪费、CPU-centric 同步开销)通过算法-系统协同解决:head 粒度近似缓存 + 零拷贝传输引擎 + GPU 中心同步,解码吞吐提升 9.3%–66.6%,精度几乎无损。
推导 $\kappa_{\text{crit}} = \kappa_M \times \kappa_{HW}$ 分析框架,将 KV offloading 下 prefill 从 compute-bound 转 memory-bound 的临界点分解为模型因子和硬件因子;实证表明真实工作负载超过该阈值 1–2 个数量级,GPU 仅消耗 22–28% TDP,99% 延迟花在 PCIe 传输上。

NetKV adds datacenter network topology and congestion awareness to decode-instance selection in disaggregated LLM inference via a lightweight operator-to-scheduler oracle; on a 64-GPU fat-tree, it cuts mean TTFT by up to 21% over round-robin and 18% over cache+load-aware baselines, with the static t
DSpark 把"起草更快更准"与"验证更省"两条线合成一个无损投机解码系统。起草端用半自回归结构:并行 DFlash 主干一次前向出全块 base logits,再挂一个轻量序列头(Markov 或 RNN)注入块内依赖以抑制后缀衰减。验证端用置信度调度:置信头估计每位前缀存活率,硬件感知调度器按实测 $\text{SPS}(B)$ 吞吐曲线动态选每请求验证长度,早停机制保证严格无损。离线接受长度超 Eagle3 约 26.7%–30.9%、超 DFlash 约 16.3%–18.4%;在 DeepSeek-V4 上较 MTP-1 每用户生成加速 60%–85%(Flash)/ 57%–78
SGLang 在 DeepEP/EPLB 之上加了两个 dispatch-time MoE 负载均衡特性:Waterfill 把 dense shared expert 当作可分派的 slot,按各 rank 当前负载"填谷"到轻负载 rank(V3/R1 +1.48%~+4.66%,V4 Flash 最佳 +4.92%);LPLB 用每层 min–max 线性规划在 redundant 副本间重分流量(+0.84%~+7.34%,无 redundant 时为负)。两者都不改 logical top-k,保持语义。
DeepSpec 是训练+评测投机解码 draft model 的全栈 Python 代码库(~6.1k LOC, MIT)。同一套 `Qwen3DSparkModel` 通过 config 开关切出 DFlash(CE-only)与 DSpark(Markov 头 + L1 分布匹配 + confidence 头),另有独立的 Eagle3(TTT) 路径。三段流水线:数据准备 → FSDP 训练 → rejection-sampling 评测,附 Qwen3/Gemma4 官方 checkpoint。
RLM is an inference-time scaffold that stops feeding a long prompt $P$ into the model's context window and instead loads $P$ as a variable inside a persistent Python REPL; the root LM sees only constant-size metadata and writes code to peek, decompose, and recursively call itself (`llm_query` / `rlm
把"包裹固定 LLM 的 harness 代码"本身当成搜索目标:一个 coding-agent proposer 通过文件系统读取全部历史候选的源码、分数、执行 trace,逐轮提出新 harness。文本分类比 ACE 高 7.7 分且 context token 少 4×;数学检索 5 个 held-out 模型平均 +4.7 分;TerminalBench-2 上超过手工 harness。
For agents that repeatedly query the *same* large external context (a 50k-entry feedback corpus, a code repo), PEEK caches the reusable "orientation knowledge" — what the context contains, how it is organized, key entities/constants/schemas — as a small constant-size **context map** kept resident in
借鉴硬件投机执行思想,将 agent 的推理-行动循环与用户输入流、工具执行流解耦(Asynchronous I/O),并允许在信息不完整时投机发起工具调用、事后修正(Speculative Tool Calling),配合 clock-based SFT 训练将 3B 边缘模型的端到端延迟降低 1.6–2.2×,同时保持接近非流式基线的准确率。
