Guardrails AI
Definition
Open-source framework that validates and corrects LLM outputs using validators. Checks formatting, content safety, and structural correctness after the model generates a response. Uses LLM-based classification to evaluate outputs — probabilistic, not deterministic. Operates between model and user, not between agent and tool.
Why It Matters
Guardrails AI solves output quality — ensuring model responses are well-formatted and safe. But output filtering is fundamentally different from execution governance. Filtering a text response is not the same as blocking a database write. They protect different surfaces.
How Exogram Addresses This
Use Guardrails AI for output formatting and content safety. Use Exogram for execution governance. They are complementary — different layers, different problems. Guardrails AI adds 50-200ms (LLM-based). Exogram adds 0.07ms (deterministic).
