Opus 5 Tops AI Bug Bounty Benchmark
Hunting for the strongest AI model to help with bug bounty work? A new benchmark from MDP Security put 10 autonomous models through 100 black-box security labs, with no source code leaks to lean on. Here is the leaderboard and what it tells you about choosing a model.

What Happened
MDP Security ran 10 autonomous AI models through 100 black-box security labs. The top result was Opus 5 with 63 solves across 303 rungs. Right behind it, Grok 4.6 scored 62 solves on 295 rungs. The next tier is a tie between DeepSeek V4 Flash and Qwen 3.8 Flash, both with 53 solves.
Why It Matters
The Flash variants are proving mature enough for recon and vulnerability assessment, which makes them worth testing if you are doing bug bounty work and want an affordable model. The gap between the top two is just one solve, so your choice between Opus 5 and Grok 4.6 might come down to cost and speed rather than raw capability.
