FrontierCS 2 - Latent Objective Recovery: leaderboard
FrontierCS 2 selected formal runs on 48 research engineering tasks, with each source-native coding harness. Paper v1 Table 3 fixes the effort settings; the subsequently added DeepSeek 1017 row leaves effort unspecified. Superseded attempts are not selected by score. Native bounded task scores are distinct from human-reference margins and from pass/fail verdicts. Explicit failed-run zeroes remain zero; unreported scores remain missing. Metric: Task score (0–100).
Metric: Task score (0–100). Source: frontier-cs.org. Saturation forecast: Estimated already saturated. 14 models tracked.
