From Search to Research: Exploring Search Scaling in Autonomous Quantitative Factor Mining

Inference scaling has been shown to improve large language model (LLM) performance, and this principle naturally extends to autonomous LLM agents through increased search budgets, which we refer to as *search scaling*. Although prior work has characterized the mechanisms, scaling behavior, and performance limits of LLM...

CalibratedRubric: Task-Adaptive Rubric Banks for Open-Ended LLM Evaluation

CalibratedRubric is introduced, a task-adaptive framework that combines type-specific scoring, Bayesian rubric-measurability filtering, and item response theory (IRT)-based bank assembly that supports CalibratedRubric as an efficient, uncertainty-aware approach to open-ended LLM evaluation.

GAUGE: Grading Agent-Built Financial Models Without a Golden Answer

GAUGE is introduced, a benchmark for evaluating agent-built valuation models against observed analyst practice rather than a single point answer, and current agents are substantially stronger at model construction than valuation judgment.

FinResearchBench II: A Deep Research Benchmark with Consensus-Derived Gold Rubrics for Distinguishing Financial Report Quality

A scalable pipeline for generating high-quality rubrics without human experts in the final loop is proposed, which is naturally scalable for benchmark evaluation, automatic system comparison, and future studies of evaluation-driven system improvement.
