Paper Proposes Message-Passing Method For Compressing LLM Weights
A new arXiv paper proposes a message-passing method for compressing large language model weights, the kind of efficiency work that underlies answer engines like Perplexity AI.
Gemini 2.5 Pro Tested in Multi-Agent Drug Safety Causality Framework
Researchers built a four-agent causality assessment system using Google's Gemini 2.5 Pro and DeepSeek-V3.2 to review drug safety case reports against expert judgment.
Independent Audit Finds Cheap Moderation Model Rivals Claude
A new paper benchmarks a cheap content moderation model against Claude and 13 other frontier reasoning systems, finding it holds up on accuracy at a fraction of the price.
Paper Finds Vague Tool Output Wording Can Mislead AI Agents and Their Verifiers
A new paper, with an audit prompt tested on Codex and Claude Code, shows vague tool output wording can mislead AI agents and the verifiers meant to catch their errors.
OpenAI Details Tighter Security For Frontier Model Training
OpenAI said it strengthened containment around how it trains frontier models, moving some ChatGPT-building work to offline environments with heavier red-teaming.
Researchers Publish S-SALAAD Framework For Sparse Large Model Inference
A new paper on compressing large models for edge devices matters to Perplexity AI and any company whose answer engine has to run inference away from a data center.
Paper Finds Claude Opus 5.5 Stays Coherent on Hidden-Variable Probability Tests
A new paper tests seven models, including Claude Opus 5.5 and Claude Haiku 5.5, on whether their probability judgments obey a basic law of probability.
Paper Describes Claude Opus Agent Designing Sub-THz Transmitter
A new paper describes Claude Opus 4.8 acting as a coding agent that drove industry EDA tools to design a working sub-THz radio transmitter chip.
Paper Tests Whether Claude and Five Other Models Can Tell a Teenager's Writing From an Adult's
A new case study finds that Claude Fable 5 and five other frontier models often mismatch handwritten exam answers to the wrong age, while voicing high confidence in the wrong guess.
Paper Compiles LLM Routing Decisions Into Parallel Inference for RAG
A new preprint shows that a large language model's section-picking decisions in hierarchical retrieval can be compiled into parallel inference instead of run one token at a time.
Paper Finds Anthropic and OpenAI Models Decline Reports by Racial Description
A new paper tests whether Anthropic's Claude and OpenAI models refuse to weigh an informant's report based on racial description alone, not evidence.
