A 184-Million-Parameter Classifier Claims State-of-the-Art Prompt-Injection Detection
The Semalith v1.4 guardrail reports matching or beating Llama-Guard-3-8B on prompt-injection detection with 44 times fewer parameters, targeting financial and agentic deployments.
A new paper introduces Semalith v1.4, a 184-million-parameter safety classifier that the authors report achieves state-of-the-art detection of prompt injection (malicious instructions hidden in a model's input to hijack its behavior), while…
