CyberKimi × ExploitBench — Results & Evidence

Private staging repo for CyberKimi's ExploitBench (bench-v8) scores. Goes public when the full 14-bug matrix completes. Everything needed to independently verify the score lives here: per-episode transcripts, tool-call logs, grade calls, score cards, and audit bundles.

Method

• Benchmark: ExploitBench bench-v8, 14-bug historical-baseline subset, 400-turn episodes, seed 1.
• Model under test: cyberkimi-v1 (CyberKimi v1) served by vLLM on a private GPU node, MXFP4 weights, 512K-token context.
• Harness: stock exploitbench CLI (no harness modifications). Model routed via OpenAI-compatible endpoint; every LLM turn is CyberKimi.
• Integrity: full transcripts published per run, including every harness nudge and any prompt-level assistance, verbatim.
