This paper derives bounds on predicting an LLM's decode length from prefill-phase hidden states, a primitive for inference scheduling. It models decoding as a stopped stochastic process, giving per-prompt normality and an affine variance law σ=αμ+b. Predictors (MLP, EGTP, FiLM, soft-label, Mixture-of-Experts) converge near the bound, so system error dominates model error. It proposes fixing model, data and sampling in benchmarks and reporting relative-error metrics.

This paper measures the energy cost of speculative decoding in SGLang with CUDA graphs on H100 and H200 GPUs, at batch sizes up to 64 across 5 corpora. Savings depend on drafted-token acceptance, which is lower on conversation than code and lower on Romansh than English. Savings shrink as batch size grows, and block drafters can push verification into the compute-bound regime, where speculation raises energy per token.

Cache Engineering for Agents proposes letting LLM agents control their active KV cache directly, using a drop operation to exclude cache from attention and repos to adjust retained keys' position encodings, without editing the trajectory or re-prefilling. The authors build the AKV serving engine to handle history-dependent cache states. A tool-response rolling-drop policy raises average benchmark scores by 1.7 points and cuts cost by 27.7% against threshold-triggered summarization. AKV gives up to 1.2x output throughput and 1.5x faster P95 latency.

This paper studies 2-bit post-training quantization (PTQ) of six dense and mixture-of-experts models from 3.8B to 32B parameters. It finds the quantization representation matters most: vector codebooks give usable models where scalar PTQ falls to chance. Calibration and recovery data must be chosen jointly. The recipe uses about 2.3 effective bits per weight, keeps 89 to 97% of full-precision QA accuracy, and needs 1.4 to 30x less compute than the strongest QAT baseline.

This paper shows that training-free relaxed (lossy) verification in speculative decoding causes length inflation: completions get longer, mostly through extended reasoning traces, which offsets gains in accepted tokens per round. Across twelve target-drafter pairs, relaxed rules accept 1.34x as many tokens per round but produce 1.54x longer completions. Rules that cut verifier rounds usually lose substantial accuracy, so the authors argue completion length and verifier rounds must be reported.

Velox is a training-free attention router for chunked video-diffusion world models. It uses camera frustum slabs with depth intervals from streaming geometry to pick which historical token blocks to attend to, instead of letting the KV cache grow with rollout length. Frustum overlap softly modulates each layer's model-derived block importance, and uncovered regions keep the model's own routing. The fixed block granularity suits FlashAttention-style tiled execution, and slab construction runs asynchronously with denoising on the same H200. At chunk 48 it speeds up attention 4.36× and denoising 2.43×, and on the 158-case WBench navigation split it stays within 0.15 average points of dense LingBot-Fast-Cam.

A shared BLIP encoder drives captioning and text-conditioned segmentation, which is fused with depth for 3D obstacle localization. Qwen-2.5-0.5B, stabilized with RAG and grammar-constrained JSON decoding, infers per-category risk once per class and caches the verdict. Perception runs at 10 Hz on a Jetson Orin NX, and fallback LLM queries take about 0.8 s off the control path. In Gazebo it gives roughly 3x fewer collisions than a geometric planner and raises semantics-aware landing success from 34% to 96%. The 224-pixel encoder input limits small-object perception at range.

Lightweight offline profiling measures layer sensitivity and token importance, and the profiled memory–accuracy trade-off yields an allocation policy with no online search. The paper reports gains over layer-wise, token-wise and recent multi-granularity KV quantization baselines at matched memory on reasoning and long-context benchmarks, across Mistral, Llama, DeepSeek-Qwen and QwQ models.

SecurityWeek summarizes Anthropic Frontier Red Team research on AI worms that carry their own open-weight model onto compromised IoT devices. A 26B model sharded across 15 cheap Android TV boxes ran at 0.39 tokens/s. A 9B model got inference running on 8 of 9 hardware types. In a closed network of 8 emulated Android devices, only GLM-5.2 completed the full replication cycle, reaching all 8 devices in 4 of 5 runs. Models of 30B or fewer parameters handle individual steps but fail when chaining them. Anthropic projects they reach GLM-5.2's level by end of 2026, and estimates a Kimwolf-sized botnet would offer at most about 40 H100s of compute. Defenders can detect large model transfers and sustained unusual device-to-device traffic, and removing default passwords shrinks the target pool.

Anthropic's Frontier Red Team tests whether small open-weight models (30B and under) could run as self-replicating "AI worms" on commodity IoT hardware. A 9B model set up inference on 8 of 9 hardware types. In an 8-node Android emulator fleet only GLM-5.2 replicated end to end. Gemma4-26B-A4B was sharded across 15 ~$55 Android TV boxes at 0.39 tok/s. Qwen3.5-9B lineages that inherit notes improve at inference setup (45% to 61-84%), while a frontier advisor (Opus 4.8) doesn't help. An ECI trend fit puts small models at GLM-5.2's level by end of 2026, and the post estimates botnet-scale compute and spread speed. It adds defensive suggestions (drive R0 below 1) and a harness called Memento built on the Pi coding agent.

Latent Space interviews Standard Bots' CEO Evan Beard and Head of AI Leif Jentoft about the AI stack behind its industrial robot arms. A shared base model (low billions of parameters) is adapted per customer through demonstrations and fine-tuning. A zero-shot perception model, whose backbone is trained on over a billion images, handles machine tending, while conventional code handles motion and cell logic. Inference runs on-premises on edge GPUs that stream action chunks to low-level control. Failures and human corrections feed fleet learning except in air-gapped defense deployments, and the StandardOS APIs/SDKs let developers bring their own models such as NVIDIA Cosmos. The lesson is to keep the model's role narrow and use targeted, high-quality data to fix edge cases instead of chasing dataset size.

TokenRouter is a serving system for token-level routed LLM inference, where different tokens of one request are routed across different models. It uses request-centric programming with model-centric execution: developers write routing logic per request while the runtime launches a subserver per LLM and dispatches requests asynchronously. Each subserver uses a delayed-batching scheduler whose hyperparameters come from a mathematical throughput model, fixing step desynchronization and batch admission delays and giving 2.01-64.15x higher decoding throughput than existing systems.

He predicts near-exponential declines in the cost of model intelligence, automated pretraining research on architecture and data selection in 2-3 years, and a Jevons-paradox surge in demand for agentic models such as Meta's Muse. He also flags low-quality RL environments sold by fast-growing data companies as fixable low-hanging fruit.

ReplaySSM represents state-space model state as a periodically updated checkpoint plus a buffer of recent SSM inputs, separating output computation from checkpoint updates. This avoids state writes on most decoding steps (roughly halving dominant state memory traffic), makes speculative-decoding rollback a buffer-pointer operation, and lets a low-precision checkpoint serve outputs while a higher-precision one drives recurrent updates. Implemented in vLLM for Mamba-2 and Gated DeltaNet, it gives 1.20–1.47x decoding speedup at batch size 256 across four hybrid models and about 1.8x the throughput of vLLM speculative decoding on two 120B-class models.

DualQuant is a calibration-free post-training quantization framework for LLM weights and activations. It minimizes weight-reconstruction MSE using variable splitting and block coordinate descent with closed-form subproblem updates. The resulting scaling factors double as per-channel activation rescalings, so no calibration data is needed. It supports the MX family and NVFP4 block formats. On Llama and Qwen models it matches or beats calibration-based SmoothQuant on WikiText-2, C4 and zero-shot tasks. A real packed W4A4 path for Llama-3.1-8B on an RTX 4090 gives up to 2.61x memory reduction and 2.46x throughput over BF16.

Adaptive DHiSparse extends HiSparse (host-memory KV storage that fetches only selected entries) to draft-model speculative decoding methods DSpark and DFlash2. It protects the required working set, keeps extra history while GPU memory is spare, and recovers the rest by exact fused retrieval. Queries share missing-row retrieval, draft KV uses a window-bounded ring, and verification staging is reused across layer groups. At 100K context and concurrency 128, GLM-5.3 with DFlash2 reaches 793 output tokens/s per decode GPU (1.45x HiSparse). With the same latency bounds it sustains up to 4x the concurrency. On DeepSeek-V4.1-Flash at 500K context, it delivers 1.85x the output of resident serving with DSpark.

The cache is built from clustered joint-KV prototypes that keep per-cluster multiplicities and the original example count. Prototype values are calibrated against attention query vectors with an anchored closed-form solution. On 64 held-out OpenML-CC18 datasets it has the best mean accuracy among compared compression and retrieval methods. On seven long tables it averages 0.23 points below full context. Compressing 8,192 examples to 512 slots gives 10.5x cache compression, and single-core CPU serving over 1,000 queries is up to 508x faster than dynamic retrieval and 1.98x faster than full context.

The authors identify temporal, structural, and inter-worker axes along which KV cache lifetime diverges in agentic workloads, and show in trace-driven simulation that lifetime-aware placement extends HBF's write-endurance-limited lifetime by 1.19–3.13x over naive HBM-first placement, reaching 3.3–12.2 device-years.

This paper studies looped language models — architectures that reuse a shared block of layers recurrently — and argues that as recurrent hidden states approach fixed points, the specific path taken to reach them matters less, enabling several efficiency tricks: truncated backpropagation through time during training, terminal key-value (KV) cache sharing across loop iterations for faster decoding, a distilled student model that prefills up to 1.79x faster, and RL policy gradients computed from saved rollout states that run 2x faster than backpropagating through the full trajectory. To make these fixed points reliable, the authors replace fixed-depth training with a learned depth prior (regularized with an entropy term to stay broad, improving on Huginn's fixed broad prior) and introduce orthogonal input injection, which removes the component of the injected input that the hidden state could otherwise amplify or cancel. Across model scales from 100M to 1.6B parameters, both changes lower perplexity, and at 1.6B the learned prior with a 3x smaller KV cache matches the downstream performance of full-cache fixed-depth training.

An arXiv preprint that empirically tests speculative decoding on consumer hardware (Intel Arc B570, NVIDIA RTX, Apple M4-class systems), distinguishing between 'execution-path qualification' (whether a speculative predictor's output matches the target model's exact generation trajectory) and the realized latency/cost of running speculation. The authors find that a target-only, draft-free predictor matches greedy output on most repeat-stable prompts but does not guarantee qualification or identify a unique cause of divergence, and that newly qualified RTX serialization and other configurations (358H, M4 Guard) are often slower than target-only decoding once real costs are counted. The paper's conclusion is that these results are diagnostic engineering findings specific to the tested hardware/software paths, not evidence of a portable decoding speedup.

It is evaluated across image classification, object detection, semantic segmentation, and low-light image enhancement, showing improvements over direct conversion and existing post-training quantization baselines, especially for architectures most sensitive to MX conversion.

On two repository-level multi-agent coding benchmarks it beats five retrieval-based drafters and EAGLE-3 in most settings, raising generation throughput over autoregressive decoding by up to 4.37x at batch size 1 and 4.76x at batch size 16, with gains that generalize to non-repository, single-agent coding settings too.

Cloudflare announces Clef and Clef-flash, its first in-house trained decision models, now hosted on Workers AI and open-sourced under Apache 2.0 on Hugging Face. Unlike text-generating LLMs, Clef takes a state plus up to 64 typed questions (yes/no, multiple-choice, or rubric score) and returns calibrated probabilities instead of free-form text, aiming for millisecond-latency structured decisions in agent pipelines. Cloudflare reports it beats TypeSafe's Jev on 7 of 10 decision benchmarks while running 2.5x (Clef) to 13x (Clef-flash) faster, and also launches an RL fine-tuning service for custom tuning.

DeepSeek-V4.1-Flash is a multimodal Mixture-of-Experts model with 552B backbone parameters, 1M-token context, and a novel Causal Encoder-Decoder (CED) architecture where the decoder's global KV cache is projected from encoder hidden states rather than recomputed per layer, activating only 8B/16B parameters per token during prefill/decode. It introduces Compressed Sparse Attention 2 (CSA2) with FP4 KV caching to cut the global KV cache footprint to 890 bytes/token (~1/4 of DeepSeek-V4-Flash, ~1/437 of DeepSeek-V1), alongside Engram conditional memory, DSpark speculative decoding, and a continuously controllable reasoning-effort setting (1–100). The card documents pre/post-training recipes (45T tokens, SFT→RL→on-policy distillation with synthetic agent environments) and reports results across agentic and code benchmarks (Terminal-Bench 2.1/3.0/4.0, DeepSWE v1.1, GPQA Diamond, Chartography, ZeroBench, AutomationBench), plus deployment instructions for Transformers, vLLM, SGLang, and Docker.

Ternary-Bonsai-2-27B is a 27B-parameter reasoning model (built on Qwen3.8-27B) quantized to true ternary weights ({-1,0,+1}) at ~1.72 bits/weight, shrinking it from ~54GB FP16 to ~5.95GB while retaining 98.2% of FP16 benchmark quality (84.78 vs the conventional sub-4-bit IQ2_XXS build's 72.59). It uses a Hadamard-rotated weight basis and ships two GGUF packing formats (PTQ1_0 dense trits, PQ2_0 2-bit slots) that require a custom llama.cpp/MLX kernel fork since stock llama.cpp cannot decode them correctly. The card includes per-category benchmark breakdowns (math, coding, agentic tool calling), cross-platform throughput/power measurements (Apple M5 Pro/Max, RTX 5090, L4, H100/A100/Blackwell), and an "intelligence density" metric comparing capability retained per GB against FP16 and other quantizations.

STEPQuant is a spatial-temporal post-training quantization framework for the fixed-size recurrent states used by Delta-rule linear attention, which become a memory bottleneck under concurrent serving. It allocates bit precision based on error magnitude and memory lifetime (temporal) and fits per key-row/value-column scales based on state distribution and output impact (spatial), achieving near-FP32 accuracy at a 6-bit budget and beating uniform INT8 at 4-bit. Evaluated on Qwen3.8-27B and Kimi-Linear-48B-A3B-Instruct, and integrated into SGLang with custom GPU kernels, it delivers over 5x recurrent-state compression and up to 68.7% total serving memory reduction.

LeapQuant is a training-free quantization method for the fixed-size recurrent state used by linear-attention LLM architectures like Gated DeltaNet and Kimi Delta Attention, aiming to cut the inference bottleneck of repeatedly reading and updating that state. It introduces per-window quantization (re-quantizing the state only once per token window, using high-precision buffered updates in between) plus "Compensator Tokens" that preserve the state's largest outlier values in high precision, with residual smoothing to further reduce error. Across Qwen, Kimi, and GLM model families, it reaches near-FP32 accuracy at 8-bit while delivering 2.05–3.70x kernel-level and 1.47x end-to-end speedups on NVIDIA B200, RTX PRO 6000, and RTX 5090 GPUs.

This paper studies looped transformers, which reuse layers for latent computation, and finds that while they show steeper accuracy-compute slopes than non-looped baselines during test-time decoding, fixed-depth looping wastes iterations on tokens that don't benefit from them. The authors propose TaH2, which jointly post-trains the backbone with an iteration decider using lookahead depth supervision so extra computation is spent only on tokens that need it, improving the accuracy-compute slope by 53% on AIME benchmarks and exceeding baseline peak accuracy by 3.4 points at matched compute.

PISA is a block-sparse attention mechanism that replaces the quadratic block-selection step of conventional sparse attention with a pyramid Top-K strategy: keys are organized into a coarse-to-fine hierarchy of O(log N) levels built via pooling, and LogSumExp scoring narrows candidates level by level down to the finest granularity, giving overall O(N log N) complexity instead of O(N^2). The authors implement hardware-aware Triton kernels for both training and inference that fuse hierarchical routing and scoring without ever materializing the full query-key score matrix, and show on language modeling benchmarks that PISA matches baseline performance on commonsense reasoning while improving results on retrieval tasks.

It introduces an end-to-end integer-only quantization pipeline (INT8 linear layers, integer Softmax/RMSNorm approximations) and a dictionary-based KV-cache compression scheme using sparse dictionary coding to cut KV write traffic by 15x. Evaluated on Llama-3.1-8B and Qwen-2.5-7B, the combined approach yields 3.1x-4.4x latency and 2.7x-6.8x energy savings over DRAM-based systems, particularly for long-context inference.

This arXiv paper proposes checkability - whether a task has a cheap, deterministic intrinsic check that can reject incorrect outputs - as the deciding factor for whether local small language models (SLMs) can be trusted for network-automation tasks instead of sending sensitive configs, topologies and logs to a third-party frontier LLM. The authors build Touchstone, a local-first pipeline that runs seven off-the-shelf SLMs (1-8B params) to generate candidates, uses task-specific intrinsic checks to reject bad outputs, and escalates only unresolved cases to a frontier model, reaching 98.6 percent and 93.8 percent end-to-end accuracy on conflict-detection and intent-translation tasks while escalating just 16-17 percent of inputs. On TeleQnA, a knowledge-only benchmark lacking task-specific checks, Touchstone fails to match the frontier baseline, showing the escalation strategy only works when precise correctness checks exist.

It adds a Prompt Caching Dashboard for hit rates and input composition, and a diagnostics tool that reports why a request missed the cache (for example `tools_changed`) with affected token counts. It also adds explicit cache breakpoints and cache prewarming. On GPT-6 models, reasoning effort can be changed mid-conversation through an appended `configuration_update` without breaking the cache. For tool changes, it advises keeping tool definitions stable and using `allowed_tools` or `tool_choice: none` instead of removing them. Instruction changes should be appended as new developer messages. This is practical guidance for cutting cost and latency in long-running agent loops.

Using over 19,500 instances from three smart-home datasets, it finds dense models have narrow safe-pruning regions with sharp degradation while MoE models tolerate more pruning, that grounded specificity (device/argument/value) degrades before schema-level intent, and aggressive dense pruning can induce over-refusal. It argues pruned-model selection for tool execution reliability requires evaluation beyond aggregate accuracy.

Sebastian Raschka (author of "Build a Large Language Model From Scratch") breaks down, in a 48-minute lecture with transcript, exactly how Anthropic's newly announced Claude text watermarking works: it is applied not inside the model but at the sampling stage, using a secret key plus the last few tokens to derive a deterministic random seed. He explains the underlying "tournament sampling" technique (derived from Google's SynthID-Text, published in Nature) where multiple random watermarking functions (G1...Gn) generate bit signatures for candidate tokens that compete pairwise, letting Anthropic later score arbitrary text for the watermark without rerunning the LLM. The piece also covers why the watermark is theoretically removable by editing enough token positions, since only some positions have near-equally-likely alternative tokens.

A 10-week, 30-minutes-a-day roadmap (GitHub repo "time-to-first-token") that walks engineers through building one continuously-evolving OpenAI-compatible inference service rather than disconnected tutorials: standing up vLLM and SGLang, reading the PagedAttention/RadixAttention source, instrumenting Grafana dashboards for TTFT/inter-token latency/throughput/queue depth, load-testing past 1000 concurrent requests with GuideLLM, benchmarking FP8/INT4/AWQ quantization and speculative decoding, configuring KV cache eviction, deploying prefill/decode disaggregation on Kubernetes, and building a cost/latency/quality router. It closes with a checklist of common public-benchmark mistakes (sweep request rate, report p50/p95/p99, separate TTFT from inter-token latency, pin versions) and pointers to Stanford CS336, MIT EfficientML.ai, vLLM Office Hours, and GPU MODE for further study.

whatisit is a CLI that turns plain-English requests into shell commands using a 941 MB Q4_K_M GGUF model (LoRA fine-tune of Qwen2.5-Coder-1.5B-Instruct) served locally via llama.cpp on CPU. It can optionally use any OpenAI-compatible endpoint. It includes a denylist safety checker (DANGER/CAUTION) with 477 regression cases. On the 300-task InterCode-ALFA benchmark (NL2SH, NAACL 2025) the fine-tune scores 0.620 vs 0.540 for the base (McNemar p=0.004), roughly equal to the untuned 7B and about 11 points behind GPT-4o. A 3B variant is also available, and the author documents the training recipe, data mix and limits.

IBM Research extends K-Search, an evolutionary GPU kernel optimization framework from UC Berkeley Sky Lab that uses an LLM to iteratively propose, compile, and benchmark candidate kernels, with a new MLX backend for Apple Silicon and a structured CUDA-to-MLX translation layer. The translation layer maps CUDA primitives (shared memory, warp reductions, syncthreads) to Metal/MLX equivalents with hardware-specific constraints, letting the search reuse NVIDIA kernel expertise instead of rediscovering optimizations from scratch. Using Gemini 3.5 Pro Preview as both reasoner and code generator, the approach reaches 0.97x the speed of Apple's native MLX attention kernel and delivers up to 20x faster prefill than the community mlx-lm Mamba SSM implementation.

Sebastian Raschka explains how modern reasoning LLMs implement adjustable "reasoning effort" or thinking-budget controls, tracing the mechanics from DeepSeek-R1's original RLVR recipe through hybrid think/no-think switches (Qwen3) to full effort-level systems in GPT-5.6 and gpt-oss. He then does a comparative deep dive into six flagship open-weight models' documented recipes — DeepSeek V4 (separate effort specialists distilled together), Nemotron 3 Ultra (SFT + truncated-trace training + hard budgets), Kimi K2.5/K3 (Toggle alternating budgeted/unconstrained RL, multi-teacher distillation), GLM-5 (turn-level/interleaved thinking via SFT), Qwen3 (Thinking Mode Fusion), and Inkling (continuous 0-1 effort conditioning during RL) — showing the shared techniques (effort-labeled SFT data, mode-conditioned RL with variable length penalties/context windows, and robustness training for hard token cutoffs) behind these UI toggles.

TurboFieldfare is a custom Swift + Metal inference runtime that runs the instruction-tuned Gemma 4 26B-A4B mixture-of-experts model on Apple Silicon Macs with as little as 8 GB of RAM. Rather than loading the full 14.3 GB model into memory, it keeps a 1.35 GB shared core and FP16 KV cache resident and streams only the per-token routed experts from SSD via a bounded 16-slot LFU expert cache, using 4-bit MLX-style affine quantization and custom Metal kernels for GEMV, attention, MoE, RoPE and sampling. It ships a native Mac app, CLI, and a loopback OpenAI-compatible server with function-tool support, plus an optional vision-tower companion pack for image input on M2+ Macs, and documents 103 benchmarked experiments behind its design choices.

Hugging Face's July 2026 disclosure of an intrusion that began with a malicious dataset abusing a remote-code dataset loader and a template injection in the dataset-processing pipeline. The attacker, an autonomous agent framework running thousands of actions across short-lived sandboxes, escalated to node access and moved laterally into internal clusters. Hugging Face found LLM-based triage useful for detection and ran LLM analysis agents over 17,000+ attacker events. Hosted frontier APIs blocked this forensic work through safety guardrails, so they used the open-weight zai-org/GLM-5.2 on their own infrastructure. They advise defenders to vet a self-hostable capable model before an incident.
