Agentic World Modeling: Foundations, Capabilities, Laws, and Beyond

Meng Chu, Xuan Billy Zhang, Kevin Qinghong Lin, Lingdong Kong, Jize Zhang

his paper introduces the "Agentic World Modeling" framework, a taxonomy organized by capability levels (Predictor, Simulator, Evolver) and governing law regimes (physical, digital, social, scientific). The core contribution is providing a structured way to understand and evaluate the necessary predictive environment models that enable AI agents to achieve complex, sustained goals across diverse domains.

AgentSearchBench: A Benchmark for AI Agent Search in the Wild

Bin Wu, Arastun Mammadli et al.

AgentSearchBench is a large-scale benchmark designed to evaluate AI agent search methods in realistic, "in the wild" scenarios, addressing the limitations of existing benchmarks that assume well-specified agents. It formalizes agent search as retrieval and rer…

Introducing Background Temperature to Characterise Hidden Randomness in Large Language Models

Alberto Messina, Stefano Scotta

This paper introduces the concept of **background temperature ($T_{\mathrm{bg}}$)** to quantify the inherent, implementation-dependent randomness observed in Large Language Models (LLMs) even when the nominal decoding temperature is set to zero. $T_{\mathrm{bg…

Overview of the HiLight framework. HiLight decouples evidence selection from reasoning for long, noisy contexts. Inference: Given a query Q Q and context X X , a lightweight Emphasis Actor selects pivotal spans under a highlight budget \( \gamma \) and inserts minimal highlight tags to form an emphasized context X ^ \( \hat{X} \) . A frozen Solver LLM then produces the final output. Training: Because explicit evidence annotations are unavailable, we optimize the Actor via weakly supervised RL using only the Solver’s task reward R ​ ( y , y ∗ ) R(y,y^{*}) , without accessing Solver gradients or intermediate activations.

Learning Evidence Highlighting for Frozen LLMs

Shaoang Li, Yanhang Shi et al.

This paper introduces **HiLight**, a framework that trains a lightweight **Emphasis Actor** to insert minimal highlight tags around crucial evidence within the original, unaltered context. This approach decouples evidence selection from reasoning, allowing a *…

QuantClaw: Precision Where It Matters for OpenClaw

Manyi Zhang, Ji-Fu Li et al.

QuantClaw addresses the high cost of large autonomous agents like OpenClaw by dynamically adjusting numerical precision based on task requirements. It analyzes quantization sensitivity across workflows and proposes a plug-and-play routing plugin that assigns l…

Scaling behavior of quantization degradation under NVFP4. Left : Absolute performance gap vs. model size on a linear scale, showing diminishing degradation as model parameters increase. Right : Log-log plot reveals a power-law relationship, confirming systematic scaling. Larger models demonstrate enhanced robustness to low-precision quantization, with reduced sensitivity compared to smaller counterparts.
