LH-Bench: Skill-Grounded Evaluation of Long-Horizon Agents on Subjective Enterprise Tasks

arXiv:2603.22744v2 Announce Type: replace Abstract: Large language models excel on objectively verifiable tasks such as math and programming, where evaluation reduces to unit tests or a single correct answer. In contrast, real-world enterprise work is often subjective and context-dependent: success hinges on organizational goals, user intent, and the quality of intermediate artifacts produced across long, multi-tool workflows. We introduce LH-Bench, a three-pillar evaluation design that moves beyond binary correctness to score autonomous, long-horizon execution on subjective enterprise tasks.

Why this matters
Why now

The proliferation of large language models necessitates better evaluation methods for real-world enterprise applications beyond simple objective tasks.

Why it’s important

This development addresses a critical gap in assessing AI agents' performance on complex, subjective business processes, which is essential for broad enterprise adoption.

What changes

The focus of agent evaluation shifts from binary correctness to a more nuanced, skill-grounded approach that accounts for context and subjective outcomes.

Winners
  • · AI agent developers
  • · Enterprises adopting AI agents
  • · SaaS providers integrating AI agents
Losers
  • · White-collar professions reliant on repetitive, multi-step workflows
  • · Companies slow to adopt agentic workflows
Second-order effects
Direct

Improved evaluation leads to more robust and reliable long-horizon AI agents.

Second

Enterprise workflows become increasingly automated and optimized by sophisticated AI agents.

Third

The definition of 'work' fundamentally shifts as AI agents assume more complex, multi-faceted tasks previously exclusive to humans.
