Guardrails AI: Enforcing Output Quality
Guardrails AI is a library for adding structural, type, and quality guarantees to LLM outputs.
One of the biggest risks of LLMs is their lack of consistency. Guardrails AI addresses this by allowing you to define a "RAIL" (Reliable AI Markup Language) schema that the model MUST follow.
Validation and Correction
Guardrails doesn't just check the output; it can automatically fix it. If a model generates invalid JSON or fails a specific validation check (like including forbidden words), Guardrails can re-ask the model with specific instructions on how to correct the error, ensuring that your application only receives valid data.
Security and Compliance
By enforcing specific output structures, Guardrails helps prevent prompt injection and ensures that sensitive data (like PII) is never leaked in the model's response, making it a critical tool for building safe and compliant AI products.
