teortaxesTex analyzes Fireworks' third-party evals: DeepSeek 1017 scores 95.36% pass@3 on CyberGym vs 0910's 94.82% — a 0.6% gain within overlapping confidence intervals. The accompanying leaderboard shows DeepSeek V4.1 Flash (1017) on top, costing just $0.23/task at 11m34s versus GLM 5.3 ($2.25) and Kimi K3 ($2.89); ExploitBench hits 96.8% at 3000 steps. He argues distinguishing high pass@1 models requires steep difficulty distributions: under a homogeneous-task assumption, 0910's 88.1% pass@1 should yield 99.8% pass@3, but the reported 94.8% implies failures concentrate on stubborn hard tasks (a first-attempt failure is itself evidence of difficulty). Covers harness settings (temp 1.0, 131k output tokens, 6h cap) and 0-3% unscorable tasks, and asks Fireworks to publish pass@1. Unofficial analysis.
