Guardrails
LangDB allow developers to enforce specific constraints and checks on their LLM calls, ensuring safety, compliance, and quality control.
Guardrails currently support request validation and logging, ensuring structured oversight of LLM interactions.
These guardrails include:
Content Moderation: Detects and filters harmful or inappropriate content (e.g., toxicity detection, sentiment analysis).
Security Checks: Identifies and mitigates security risks (e.g., PII detection, prompt injection detection).
Compliance Enforcement: Ensures adherence to company policies and factual accuracy (e.g., policy adherence, factual accuracy).
Response Validation: Validates response format and structure (e.g., word count, JSON schema, regex patterns).
Guardrails can be configured via the UI or API, providing flexibility for different use cases.
Guardrail Templates
LangDB provides prebuilt templates to enforce various constraints on LLM responses. These templates cover areas such as content moderation, security, compliance, and validation.
The following table provides quick access to each guardrail template:
Detects and filters toxic or harmful content.
Validates responses against a user-defined JSON schema.
Detects mentions of competitor names or products.
Identifies personally identifiable information in responses.
Detects attempts to manipulate the AI through prompt injections.
Ensures responses align with company policies.
Validates responses against specified regex patterns.
Ensures responses meet specified word count requirements.
Evaluates sentiment to ensure appropriate tone.
Checks if responses are in allowed languages.
Ensures responses stay on specified topics.
Validates that responses contain factually accurate information.
