Tier B
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.

- built by Abundant
- in curated RL directories (5 pts)
On X · well regarded, moderate buzz, from 15 posts about SWE-Marathon in the last month
SWE-Marathon is cited by Moonshot and Meta as a headline long-horizon coding benchmark in model launches, though scores are mostly self-reported and some urge independent verification.
