Opir: Efficient Multi-Task Safety Classification for Toxicity, Jailbreaks, Hate Speech, and Harmful Content
arXiv:2605.29659v1 Announce Type: new Abstract: Real-time safety filtering for large language model (LLM) applications requires classifiers that can detect unsafe prompts, toxic language, jailbreak attempts, and unsafe responses without the cost profile of large guardrail models, and that can distinguish benign sensitive text from genuinely covert harmful content. In this paper, we introduce Opir, a family of encoder-based guardrail models built on the GLiClass architecture. Opir includes multi-task models for binary safe/unsafe classification, multi-label toxicity classification, jailbreak cl
As LLM applications proliferate, the need for efficient and reliable safety mechanisms becomes critical to prevent misuse and ensure responsible deployment.
This development addresses a core limitation in LLM deployment by offering a faster and more economical method for real-time safety filtering, potentially accelerating enterprise adoption.
The introduction of Opir provides a specialized, efficient guardrail model architecture that can differentiate nuanced harmful content from benign sensitive text, reducing the overhead of current larger guardrail solutions.
