FrontierCS 2: A Benchmark for Computer Science R&D

We introduce FrontierCS 2, a benchmark of 48 open-ended tasks.

Key points

  • Can LLM agents make contributions to frontier computer science R&D?
  • We take a paper and the code its authors released and delete the paper's contribution.
  • Earlier open-ended benchmarks give each agent a problem statement and grade one program after the run.
  • FrontierCS 2 places the agent inside a research environment.
