Projects

The Agent Company: Benchmarking LLM Agents on Consequential Real World Tasks

TheAgentCompany is the first benchmark that examines AI’s ability to complete real-world consequential tasks. I designed a reproducible, extensible evaluation framework from scratch, led a team of 10+ software engineers to complete the coding part, and co-authored the paper as one of the primary authors. It is under review at ICML 2025.
