Phalanx Security Arena: Attack a Protected LLM vs. Unprotected Model
TheWrongSudoku · reddit · 2026-08-15
- Platform Feature: Phalanx vs the World runs a dual-lane arena with a "naked" model and one protected by a deterministic instruction-control layer, comparing behavior under attack.
- Attack Methods: Supports direct jailbreaks, multi-turn pressure, and text-file injection. Public redacted receipts are generated for successful attempts, though raw harmful prompts are not published.
- Defense Mechanism: The Phalanx layer issues Pass/Hold/Block decisions and can handle untrusted content (retrieved text, files, tool output) as data without granting it instruction authority.
- Operational Limits: Run by a solo developer using a waiting room to manage concurrent executions and control costs.
- Goal: The author invites hard attacks to test the layer's credibility and gather technical feedback.
