Summary

Researchers introduce OmegaUse-OfficeVal, a new benchmark for evaluating LLM agents on complex office-suite tasks, incorporating human labor time and task price to assess economic viability. The benchmark reveals current LLMs are faster and cheaper than humans but lack comparable quality.

This paper introduces OmegaUse-OfficeVal, a novel benchmark designed to rigorously evaluate large language model (LLM) agents on multi-step, real-world office-suite tasks. Unlike previous benchmarks, OmegaUse-OfficeVal integrates economic grounding by pairing each task with estimated human labor time and a task price proxy. This allows for a direct comparison between the operational costs of LLM inference and traditional human labor. The benchmark consists of 100 tasks derived from actual practitioner requests, requiring an average of 2.32 hours of human effort. Initial evaluations using frontier LLMs against a human baseline indicate that while AI agents are significantly faster and cheaper, their deliverable quality has not yet reached human standards. The project provides open-source code and datasets to support further research and development in this area.

Why it matters

Professionals can use this benchmark to understand the current capabilities and economic trade-offs of deploying LLM agents for office automation, guiding strategic decisions on AI adoption.

How to implement this in your domain

  1. 1Review the OmegaUse-OfficeVal benchmark tasks to identify potential automation opportunities within your organization.
  2. 2Pilot LLM agents on specific, well-defined office tasks, comparing their performance and cost against human baselines.
  3. 3Utilize the economic grounding metrics from the benchmark to calculate potential ROI for AI-driven automation initiatives.
  4. 4Integrate quality verification steps into LLM agent workflows, acknowledging current limitations in deliverable quality.

Dual Teachers Improve Adversarial Robustness and Accuracy.

This work extends Information Bottleneck Distillation (IBD) by introducing a "clean teacher" alongside a robust teacher to improve the robustness/accuracy tradeoff against adversarial attacks. The proposed method transfers features from both teachers to a student model, achieving better clean accuracy while maintaining adversarial robustness, outperforming original IBD and competing with state-of-the-art approaches.
