SlideGen: Collaborative Multimodal Agents for Scientific Slide Generation

SlideGen is a collaborative vision‑language multi‑agent framework designed to generate scientific presentation slides from research papers. It assigns specialized agents to outline the presentation structure, align figures and tables with key claims, generate speaker notes, and compose editable PPTX slides using a diverse layout library. The system introduces a geometry‑aware density metric to evaluate visual clutter and demonstrates significant improvements in layout balance, content coverage, and text coherence over existing baselines on a 200‑paper benchmark.

Accelerating Diffusion Language Models via Structured Suffix Modeling

The paper introduces a training‑free structured suffix modeling technique to accelerate Diffusion Language Models (DLMs). It partitions the suffix into local, middle, and tail regions, retaining varying numbers of tokens per region and incorporating previous decoding results into current token representations. Experiments on three DLMs show significant speedups—up to 72.81× in long‑sequence inference—while often improving performance, and the method is compatible with existing acceleration strategies.

Don't Repeat Yourself: Stopping Verbatim Loops at Sampling Time

The paper introduces DRY, a sampling-time logit adjustment that penalizes token generation only when it would extend the current suffix into an exact repetition of an earlier span, thereby preventing verbatim loops in large language model outputs. Experiments across models ranging from 1.5B to 120B parameters and various prompt families show that DRY cuts suffix-extension rates by 47% and improves lexical diversity, while preserving benchmark performance. The method has been adopted by popular open-source LLM inference frameworks, indicating its practical relevance.

Can an LLM Forget the Right Things?

The article discusses a specialized LLM inference runtime designed for real-time applications, such as a 33 ms robot control cycle. Unlike typical runtimes that ignore physical deadlines, this system refuses new requests when the deadline is at risk, evicts key‑value cache entries based on meaning rather than age, and is implemented entirely in hand‑written CUDA without relying on cuBLAS or libtorch.

Speculative Decoding on CPUs: Nearly 4x Faster Token Generation with DFlash

Speculative decoding leverages idle CPU resources to accelerate token generation without altering model outputs. In vLLM benchmarks, DFlash achieved a 3.92× increase in autoregressive throughput using Qwen3.5‑9B on an Intel Xeon 6 at a concurrency of 1. The article details the origins of this speedup, discusses acceptance metrics, and outlines factors that influence when speculation is beneficial.
