CodeForces (with tools)

CodeForces (with tools) is a benchmark for hard reasoning in science, technology, engineering and math. The official description says: "CodeForces (with tools) - competitive programming rating evaluated with terminal tool access similar to Codex CLI". Below we describe in simple words what benchmarks of this type generally examine.

CodeForces (with tools) measures hard reasoning in science, technology, engineering and math. In detail, it checks:

• graduate- and expert-level questions in science and math
• multi-step derivations where each step must be correct
• problems written to defeat memorisation (novel or recent exam problems)
• correct use of formulas, units and logical inference

The score is an Elo rating, built from head-to-head comparisons between models (like chess ratings). The number is only meaningful relative to the other rated models — higher is better.

Official methodology note: CodeForces (with tools) - competitive programming rating evaluated with terminal tool access similar to Codex CLI.

What does CodeForces (with tools) test?

CodeForces (with tools) mainly measures hard reasoning in science, technology, engineering and math. Concretely, it checks: graduate- and expert-level questions in science and math; multi-step derivations where each step must be correct; problems written to defeat memorisation (novel or recent exam problems).

How is the CodeForces (with tools) score calculated?

The score is an Elo rating, built from head-to-head comparisons between models (like chess ratings). The number is only meaningful relative to the other rated models — higher is better.
