Alchemax-5 System Card & Frontier Safety Evaluation

Authors: Alchemax Preparedness & Alignment Group Institution: Alchemax Labs Research

Abstract & Key Findings

Before deploying any frontier model, Alchemax Labs conducts rigorous internal and external red-teaming under our Frontier Preparedness Framework. This System Card details the methodology, quantitative thresholds, and mitigation layers built into Alchemax-5.

Over 140 independent domain experts in offensive cybersecurity, biosecurity, and critical infrastructure tested pre-release checkpoints of Alchemax-5 over an eight-week period. We implemented multi-layer circuit breakers and representation-level refusal monitors that block high-risk dual-use synthesis while preserving 99.4% helpfulness on benign technical research.

Our findings confirm that while Alchemax-5 exhibits expert-level defensive code auditing and scientific reasoning, our alignment controls effectively prevent autonomous cyber-exploitation and hazardous material design.
