Security researcher: open-weight models beat closed ones for blackbox bug bounty workflows
rez0__ · x · 2026-10-10
Security researcher rez0 amplified and endorsed a take on model selection for bug bounty workflows:
- Open-weight models suit blackbox targets: closed models tend to be more hesitant when probing blackbox web apps; most cases don't need a frontier closed model.
- Specific picks: DeepSeek V4.1 Flash or MiMo V2.6 Flash get the job done for blackbox vulnerability hunting.
- Whitebox and low-level research: GPT-5.6 Sol with daybreak remains the king.
- rez0 adds: if you can afford the "diamond drill" (top closed model), just use it.
A practical model-selection heuristic by target type for anyone building AI-powered security workflows.
