Semalith v1.4: A Calibrated 184M Safety Classifier Achieving State-of-the-Art Prompt-Injection Detection at 44x Fewer Parameters than Llama-Guard-3-8B
Semalith v1.4 is a 184M-parameter DeBERTa-v3-base classifier that performs three-axis safety classification in a single forward pass.
Designed for financial and agentic environments, Semalith v1.4 handles prompt injection, general harm, and regulatory compliance simultaneously. It achieves state-of-the-art detection performance while being 44x smaller than Llama-Guard-3-8B, making it highly efficient for production guardrail deployment.
