Summary

FinResearchBench II introduces a scalable, expert-free pipeline for evaluating deep research agents that generate long-form financial reports. This benchmark addresses the bottleneck of human expert reliance in defining and executing high-quality rubrics. The system uses 104 real-world financial queries and automatically synthesizes 14,450 query-specific candidate rubrics from model-generated reports. A three-LLM judge panel, validated against human experts with 98.67% label-level agreement on jointly unanimous items, screens these candidates. Through strict consistency and distinguishability filters, 2,600 "consensus-derived gold rubrics" are retained. These rubrics differentiate 10 deep research systems, showing item-level pass rates from 58.58% to 22.23%, demonstrating a robust and scalable evaluation signal.

Key takeaway

For AI Scientists and Machine Learning Engineers developing deep research agents for financial analysis, you should consider adopting LLM-driven rubric generation and evaluation. This approach offers a scalable alternative to human-expert-dependent methods, enabling more frequent and comprehensive benchmarking. By focusing on consistency and distinguishability in your evaluation criteria, you can achieve robust system comparisons and identify clear areas for agent improvement, moving beyond generic metrics to fine-grained, domain-specific quality assessment.

Key insights

LLM-based evaluation, validated against human experts, can scalably generate high-quality rubrics for deep research agent performance.

Principles

• Rubric quality requires consistency and distinguishability for effective evaluation.
• LLM unanimity can reliably screen rubrics at scale, replacing human expert execution.
• Expert-free pipelines enable scalable benchmark evaluation and system comparison.

Method

The pipeline involves generating 14,450 candidate rubrics from reports, validating an LLM judge panel against human experts, then applying strict consistency and distinguishability filters to derive 2,600 gold rubrics.

In practice

• Automate rubric generation for financial report evaluation.
• Compare deep research systems using LLM-derived rubrics.
• Improve agent performance via evaluation-driven feedback.
