MRVQ: One Resident Index for Dimension- and Rate-Elastic Vector Search
Elastic Vector Search and the Memory-Rate-Dimension Trade-Off Dense-retrieval services operating at scale must continually adapt to shifting constraints. Latency budgets shrink, quality thresholds rise, and memory footprints becom...
FrugalEvo: Towards Cost-Aware LLM-Guided Program Evolution
Prior work on LLM-guided evolutionary methods such as AlphaEvolve has demonstrated strong results on computational optimization problems, including circle packing. However, these approaches typically optimize for performance gain...
Pivot-SD: Efficient Self-Distillation for Masked Diffusion Language Models
Masked diffusion language models (dLMs) present a parallel alternative to autoregressive models for complex reasoning, yet they encounter a credit-assignment problem: a few commitments during denoising sharply reduce uncertainty o...
"Torturing" LLMs in a Robot Prison Has Triggered the Dumbest Debate in AI Yet
GitHub project puts locally hosted LLMs through Saw-style experiments A GitHub project has sparked heated discussion on X after its creator began running torture and pain experiments on a series of large language models run locall...
OpenAI safety leader quits, warning AI company's culture is 'broken'
A safety leader at OpenAI has quit the company, warning that its culture was broken and that AI firms were not "being nearly careful enough" about developing the technology. David Robinson, who led the writing of safety reports th...
Embedding Prediction Helps Image Generation
LLMs are increasingly applied to cybersecurity workflows, where they are expected to translate analysts' intent into tool invocations. However, existing evaluations focus on knowledge-based assessments or end-to-end agentic tasks,...
ScholarCatalyst: A Benchmark for Retrieving Papers That Inspire New Research
Author-Annotated Benchmark for Scientific Paper Retrieval ScholarCatalyst introduces a benchmark designed to study how researchers identify prior work that inspired their projects. The dataset was built by having 184 lead authors...
VISTA: A Visual Harness for Reasoning in an Interactive World
We show that multimodal models possess strong reasoning abilities and that an appropriate harness can unlock their potential to solve tasks across diverse interactive environments. We introduce VISTA, a visual harness that gives a...
KaliBench: A Fine-Grained Benchmark for Cybersecurity Tool Use on Kali Linux with Runtime-Free Verifiable Rewards
Large language models now appear in security workflows where analysts expect them to turn natural language into exact tool invocations. Existing benchmarks test knowledge or end-to-end agent behavior, but they skip the core challe...
Cost-augmented Schrödinger bridges on graphs are exactly solvable: a Feynman-Kac tilt replaces learned control
The generalized Schrödinger bridge on a graph moves mass between two distributions while charging a cost for the states visited. Previous work has approached this by learning the rates of a controlled continuous-time Markov chain...
