Codeforces B
AI benchmark · Coding
What is Codeforces?
Codeforces evaluates models on competition-level programming problems from the Codeforces platform, reporting human-comparable Elo ratings.
Coding mostly
“standardize a CodeForces evaluation benchmark to assess the competition-level coding capabilities of LLMs and reflect their corresponding sophisticated reasoning abilities.”

Lineage
Benchmarks this one is built on and built from: versions, subsets, extensions and the indexes that combine them.
Derived benchmarks
Codeforces ELO extension
Tier B
Established: 15 or more models scored, or curated RL directories rate it.
How much stands behind a tier: usage, who backs it, a confirmed line from its own site or paper, and a clear read on X. High with three of the four, medium with two, low otherwise.
- no usage data
- in curated RL directories (1 pt)
- its family includes Codeforces ELO (tier A)
On X · unclear, low buzz, from 1 post about Codeforces in the last month
Codeforces shows up mainly as one row in DeepSeek model-card score tables, with little discussion of the benchmark's own quality or reliability.
How we got to tier B
- Adoption: no usage data. Tier D.
- On X: unclear, low buzz. “Codeforces shows up mainly as one row in DeepSeek model-card score tables, with little discussion of the benchmark's own quality or reliability.” No move.
- In curated RL directories: 1 point, a floor of none.
- Root of a benchmark family that includes Codeforces ELO (tier A): raised to B, one step below.
- Confirmed: a line from its own site or paper places it.
A clear view on X moves a tier one step up or down; most entries don't move. How tiers work.
