Call ApplyGuardrail twice, once with source INPUT before the model and once with source OUTPUT after, since the policies that apply differ\n2. Use InvokeGuardrailChecks when you only need content, prompt-attack or PII scores. It needs no guardrail id and runs in detect-only mode\n3.

Retry ThrottlingException (429) and ServiceUnavailableException (503) with exponential backoff, but treat a 400 ServiceQuotaExceededException as a quota to raise\n\n### Azure AI Content Safety (Prompt Shields)\n\n1. Send retrieved pages and tool results in the documents array of shieldPrompt, not in userPrompt, so document attacks are reported separately\n2. Call text:shieldPrompt over REST with api-version=2024-09-01. The Python SDK 1.0.0 has no method for it\n3. Keep each request under 10,000 characters across prompt and documents, and split long tool results\n4. Create the resource in a region that lists Prompt Shields, since not every region has it\n5. On F0 you get 5 requests a second. Queue checks or move to S0 before load testing\n\n## Other comparisons with Amazon Bedrock Guardrails or Azure AI Content Safety (Prompt Shields)\n\n- [Amazon Bedrock Guardrails vs Google Cloud Model Armor](https://www.anchorterminal.com/compare/amazon-bedrock-guardrails-vs-google-model-armor.md)\n- [Amazon Bedrock Guardrails vs Guardrails AI](https://www.anchorterminal.com/compare/amazon-bedrock-guardrails-vs-guardrails-ai.md)\n- [Amazon Bedrock Guardrails vs Lakera Guard (Check Point AI Guardrails)](https://www.anchorterminal.com/compare/amazon-bedrock-guardrails-vs-lakera-guard.md)\n- [Amazon Bedrock Guardrails vs NVIDIA NeMo Guardrails](https://www.anchorterminal.com/compare/amazon-bedrock-guardrails-vs-nemo-guardrails.md)\n- [Azure AI Content Safety (Prompt Shields) vs Google Cloud Model Armor](https://www.anchorterminal.com/compare/azure-ai-content-safety-vs-google-model-armor.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- [Azure AI Content Safety (Prompt Shields) vs Lakera Guard (Check Point AI Guardrails)](https://www.anchorterminal.com/compare/azure-ai-content-safety-vs-lakera-guard.md)\n- [Azure AI Content Safety (Prompt Shields) vs NVIDIA NeMo Guardrails](https://www.anchorterminal.com/compare/azure-ai-content-safety-vs-nemo-guardrails.md)\n- [Amazon Bedrock Guardrails vs Mistral Moderation API](https://www.anchorterminal.com/compare/amazon-bedrock-guardrails-vs-mistral-moderation.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 Mistral Moderation API](https://www.anchorterminal.com/compare/azure-ai-content-safety-vs-mistral-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",
