🛡️ LLM-Fort Guardrails Suite (v1)
LLM-Fort Guardrails is a suite of 7 security-focused LoRA adapters fine-tuned on top of Qwen/Qwen3-4B-Instruct-2507. These adapters serve as lightweight, high-performance security guardrails mapped to critical safety boundaries.
By offloading classification and security checks to lightweight adapters, the system achieves enterprise-grade security filtering without degrading the inference performance of the main application model.
