Elo-per-token Analysis Measures Test-Time Scaling in LLM Agents
A new arXiv paper proposes an Elo-per-token method to assess how LLM agents spend test-time compute while revising answers, calling tools, exploring options, and deciding when to stop. Because agents allocate that compute adaptively, conventional measures struggle to capture how their performance scales, which the authors aim to address with their token-level rating approach.
