CodegenBench - LeetSunway: leaderboard

The LeetSunway part of CodegenBench (2026): 20 computation kernels that must be written for the SW26010 many-core processor of the Sunway TaihuLight supercomputer, using its master-slave core paradigm with little public example code. Pass@1 in percent, zero-shot; higher is better.

Metric: Pass@1 (%): share of problems whose first generated program compiles, runs and matches the reference output within tolerance; zero-shot through the official APIs with a short optimization system prompt, on the 20 LeetSunway kernels that must use the master-slave core paradigm of the SW26010 processor (Sunway TaihuLight, swgcc); higher is better. Source: arxiv.org. Saturation forecast: Around February 2027. 9 models tracked.
