Coding benchmark
FrontierSWE leaderboard
Every model the catalog carries a published FrontierSWE value for, ranked by that value.
An ultra-long-horizon software-engineering benchmark with open-ended implementation, performance, and research tasks designed to challenge frontier coding agents.
FrontierSWE ranking
3 models with a published FrontierSWE value, ordered by that value, highest first. Models the source has not scored on this benchmark are not listed — they are unmeasured, not last.
| Rank | Model | Provider | Mean@5, best@5, average rank, and dominance |
|---|---|---|---|
| 1 |  Kimi K3 | Moonshot AI | 81.2 |
| 2 |  GLM-5.3 | Z.AI | 78.1 |
| 3 |  Qwen3.8 Max | Alibaba | 73.5 |
Evidence key: Observed
Rows are ordered by the value FrontierSWE: Benchmarking coding agents at the limits of human abilities published, highest first. The source does not state whether a higher value is the better result, so this page does not either: for a benchmark that measures a rate of failure, read the table from the bottom.
