    Can We Trust LLM Judges: A Study of Capability-Dependent Biases and Multi-Judge Ensemble for Bias Calibration

    The paper examines bias in LLM-as-judge setups for absolute scoring, where a single model’s capability affects its scoring behavior. It also studies ensemble calibration as a mitigation strategy.

    Concrete lesson on evaluation harness design: judge capability and calibration matter as much as prompt format.

  8. ● Top story

    Harness or Model? Isolating the Harness Effect in Agentic Coding with a Contamination-Controlled Private Suite

    This study separates model capability from harness design in agentic coding systems using a contamination-controlled suite. It tests whether improvements come from the model, the tools, or the control flow around them.

    Directly useful for agent builders: harness design can dominate apparent model gains.

  9. ● Top story

    RodForesight: A World Model Enhanced Diffusion Policy for Slender and Material Agnostic Rod Insertion

    The paper targets precision rod insertion in manufacturing, where narrow clearances and deformable interactions make standard peg-in-hole assumptions fail. It combines a world model with diffusion policy learning for the insertion task.

    Interesting example of coupling predictive world models to hard real-world manipulation.

  10. ● Top story

    Physics as the label for measuring and correcting materials reasoning in multimodal models

    This paper evaluates multimodal models on materials reasoning using physics constraints rather than only final human labels. It focuses on detecting invalid property predictions and correcting them against physical law.

    Good example of replacing weak label supervision with a stronger domain-consistency signal.

    ChitraMiti: Benchmarking Visual Grounding and Modality Reliance in Bengali Geometric Reasoning

    The benchmark tests vision-language models on Bengali planar geometry problems with structured diagram descriptions and manually extracted diagrams. It measures whether models actually ground the diagram rather than rely on text priors.

    Solid evaluation work for multimodal geometry and low-resource-language grounding.

    Announcing the World API

    World Labs is exposing a public API for generating explorable 3D worlds from text, images, and video. The announcement positions Marble’s world-model capabilities as a developer-facing service.

    Worth tracking as a platform shift: world generation packaged as an API, not just a demo.

  13. ● Top story

    Marble: A Multimodal World Model

    World Labs says Marble is its frontier multimodal world model and is now broadly available. The post frames the system as a general world-model product rather than a single-task generator.

    Useful for understanding how a world model is being productized and exposed to users.
