Overview
IBM Granite Guardian 3.2 5B is a specialized model for risk detection in prompts, responses, and multi-turn conversations. Built on instruction-tuned Granite language models and informed by IBM's Risk Atlas, it identifies harms such as hate, violence, and misinformation across diverse enterprise scenarios. It supports use cases like AI guardrails, RAG validation (context relevance, groundedness, answer relevance), and function call assessment within agentic workflows. Trained on a mix of human-annotated and red-teamed synthetic data, it outperforms peer models on safety benchmarks. Released under Apache 2.0, it aligns with IBM's AI Ethics principles.
Highlights
- Granite Guardian 3.2 5B excels in identifying various risks in prompts and responses, including social bias, jailbreaking, violence, profanity, sexual content, unethical behavior, harm engagement, and evasiveness. It also assesses hallucination risks in RAG pipelines, such as context relevance, groundedness, and answer relevance.
- Through iterative pruning and healing, approximately 30% of the original parameters were removed from the model, resulting in faster inference and lower resource consumption without compromising performance. It outperforms other open-source models in standard benchmarks.
- Designed for diverse enterprise applications, Granite Guardian 3.2 5B is effective in detecting harm-related risks within prompt text, model responses, or conversations. It also evaluates function calling risks within agentic workflows, assessing intermediate steps for syntactic and semantic hallucinations.
