Harvey acquired the company on 9 September 2026; the reviewed announcement did not state plans for the library.\n\n**OpenAI Moderation API.** Free, on any OpenAI project key. No prompt-injection, jailbreak or PII detection.\n\n## Before you call either\n\n### Guardrails AI\n\n1. Pin guardrails-ai==0.11.0 and each guardrails-ai-\u003cvalidator\u003e package, install only from PyPI, and never install 0.10.1\n2. Import validators from guardrails_ai.\u003cname\u003e, not guardrails.hub, and don't run guardrails hub install\n3. Pass use_local=True to detect_pii, toxic_language and the other model-backed validators, or set validation_endpoint to a server you run\n4. Set enable_metrics to false in ~/.guardrailsrc if you don't want usage metrics sent\n5. Avoid building on reask and RAIL. The open 1.0.0 issues plan to remove both\n\n### OpenAI Moderation API\n\n1. Read category_scores rather than flagged alone. The default thresholds are OpenAI's\n2. Pin omni-moderation-2024-09-26 if the scores feed a decision you audit. The latest alias will move\n3. Send an array of inputs in one call and match results by index to stay under the per-minute limit\n4. Add a moderation object to a Responses call instead of a second request when you only need scores on the generation\n5. Pair it with a separate injection detector. A clean result says nothing about a hidden instruction in a tool result\n\n## Other comparisons with Guardrails AI or OpenAI Moderation API\n\n- [Amazon Bedrock Guardrails vs Guardrails AI](https://www.anchorterminal.com/compare/amazon-bedrock-guardrails-vs-guardrails-ai.md)\n- [Azure AI Content Safety (Prompt Shields) vs Guardrails AI](https://www.anchorterminal.com/compare/azure-ai-content-safety-vs-guardrails-ai.md)\n- [Google Cloud Model Armor vs Guardrails AI](https://www.anchorterminal.com/compare/google-model-armor-vs-guardrails-ai.md)\n- [Guardrails AI vs Lakera Guard (Check Point AI Guardrails)](https://www.anchorterminal.com/compare/guardrails-ai-vs-lakera-guard.md)\n- [Guardrails AI vs NVIDIA NeMo Guardrails](https://www.anchorterminal.com/compare/guardrails-ai-vs-nemo-guardrails.md)\n- [Amazon Bedrock Guardrails vs OpenAI Moderation API](https://www.anchorterminal.com/compare/amazon-bedrock-guardrails-vs-openai-moderation.md)\n- [Azure AI Content Safety (Prompt Shields) vs OpenAI Moderation API](https://www.anchorterminal.com/compare/azure-ai-content-safety-vs-openai-moderation.md)\n- [Google Cloud Model Armor vs OpenAI Moderation API](https://www.anchorterminal.com/compare/google-model-armor-vs-openai-moderation.md)\n- [Guardrails AI vs Mistral Moderation API](https://www.anchorterminal.com/compare/guardrails-ai-vs-mistral-moderation.md)\n- [Lakera Guard (Check Point AI Guardrails) vs OpenAI Moderation API](https://www.anchorterminal.com/compare/lakera-guard-vs-openai-moderation.md)\n- [Mistral Moderation API vs OpenAI Moderation API](https://www.anchorterminal.com/compare/mistral-moderation-vs-openai-moderation.md)\n- [NVIDIA NeMo Guardrails vs OpenAI Moderation API](https://www.anchorterminal.com/compare/nemo-guardrails-vs-openai-moderation.md)\n",
