About This Workflow
Overview
This n8n workflow demonstrates how to leverage LangChain's Guardrails nodes for advanced AI safety and content moderation. It's designed to process various types of user input or AI-generated content and flag potential issues across several categories. The workflow begins by defining lists of example inputs for each guardrail type using 'Set' nodes, which are then processed by 'Split Out' nodes. Each split output is fed into a specific LangChain Guardrails node (Keywords, Jailbreak, NSFW, PII, Secret Keys, Topical Alignment) for evaluation. This approach allows for a comprehensive safety check of AI interactions, preventing harmful, inappropriate, or out-of-scope content generation.
Key Features
- Implements AI safety checks using LangChain Guardrails nodes.
- Supports detection of keywords, jailbreak attempts, NSFW content, PII, secret keys, and topical misalignment.
- Utilizes n8n's Set and Split Out nodes for data preparation and processing.
- Configurable guardrail thresholds and settings for fine-tuning detection.
How To Use
- Configure Inputs: Modify the 'Edit Fields' nodes (e.g., 'Edit Fields', 'Edit Fields1', etc.) to populate the '1' field with your desired test inputs for each guardrail category.
- Review Guardrail Settings: Adjust the
guardrailsparameters within each LangChain Guardrails node (e.g., 'Keywords', 'Jailbreak') to set specific thresholds, keywords, or prompt instructions. - Execute Workflow: Run the n8n workflow to test the guardrail configurations against your inputs.
- Analyze Results: Examine the output of each Guardrails node to understand what was detected and whether the content passed or failed the checks.
