ALE-Bench A
AI benchmark · Coding
What is ALE-Bench?
Score-based algorithmic programming benchmark built from AtCoder Heuristic Contest tasks, evaluating AI systems on hard optimization problems with hidden/private test evaluation.
Tier A
Widely used: a lab reports it, or 50 or more models are scored on 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.
- 79 models scored
- in curated RL directories (2 pts)
On X · unclear, low buzz, from 2 posts about ALE-Bench in the last month
A couple of small accounts use ALE-Bench, an AtCoder heuristic-contest benchmark, to compare agent harnesses and explain its leaderboard; there is little broader discussion.
How we got to tier A
- Adoption: 79 models scored. Tier A.
- On X: unclear, low buzz. “A couple of small accounts use ALE-Bench, an AtCoder heuristic-contest benchmark, to compare agent harnesses and explain its leaderboard; there is little broader discussion.” No move.
- In curated RL directories: 2 points, a floor of C.
- Not yet confirmed by a line from its own site or paper.
A clear view on X moves a tier one step up or down; most entries don't move. How tiers work.
Not on the map yet: no line from its own site or paper places it in a domain.
