OAuth only, and a template must exist in the same location as the endpoint before the first call.\n\n**OpenAI Guardrails.** MIT-licensed wrapper that adds twelve configurable checks to OpenAI client calls from one JSON file, with tool-level injection checks for the Agents SDK. The README labels it a preview at version 0.3.3, and by default a check that fails to run is reported as passed unless `raise_guardrail_errors=True` is set.\n\n## Before you call either\n\n### Google Cloud Model Armor\n\n1. Create one template per location you call from. A template in us-central1 doesn't answer on the europe-west2 endpoint\n2. Call `sanitizeUserPrompt` before the model and `sanitizeModelResponse` after, and read filterMatchState on both\n3. Treat EXECUTION_SKIPPED as unchecked, not clean. It means the input went over the filter's 65,536-token cap\n4. Pin the template to the Stable alias and move off v1 and v2 before 17 December 2026. In asia-northeast3, v1 stays the Stable version\n5. Retry 500, 502, 503 and 504 with truncated exponential backoff, and keep fan-out under the 1,200 queries a minute shared by the project\n\n### OpenAI Guardrails\n\n1. Pass `raise_guardrail_errors=True` to the client. The default treats a check that failed to run as passed\n2. Run `python -m spacy download en_core_web_sm` before using Contains PII, or client initialisation fails\n3. Catch `GuardrailTripwireTriggered`, and append a user message to history only after the call returns without it\n4. Use `block=true` for Contains PII in the output stage. Masking works only in the pre-flight stage\n5. Keep `stream=False` where output must be checked before it is shown, and budget one extra model call per LLM-based check\n\n## Questions\n\n### Which is better for AI agents, Google Cloud Model Armor or OpenAI Guardrails?\n\nGoogle Cloud Model Armor scores 77.9 (BB) on agent readiness against OpenAI Guardrails's 69.5 (B), and leads in 5 of 7 scored categories. OpenAI Guardrails leads on payments \u0026 pricing.\n\n### Can an agent call Google Cloud Model Armor and OpenAI Guardrails without installing anything?\n\nGoogle Cloud Model Armor has a hosted endpoint at https://modelarmor.{location}.rep.googleapis.com/v1/projects/{project}/locations/{location}/templates/{template}:sanitizeUserPrompt. No hosted endpoint is listed for OpenAI Guardrails.\n\n### Are Google Cloud Model Armor and OpenAI Guardrails open source?\n\nNo open-source release is listed for Google Cloud Model Armor. OpenAI Guardrails is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/google-model-armor-vs-openai-guardrails.json, and with the fewest tokens: https://www.anchorterminal.com/compare/google-model-armor-vs-openai-guardrails.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"google-model-armor\", \"b\": \"openai-guardrails\"}`.
