Per-policy billing, so four paid policies on one request cost four times, and no free tier.\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### Amazon Bedrock Guardrails\n\n1. 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. Set outputScope FULL when you want assessments for content that passed, not only for interventions\n4. Budget in text units of 1,000 characters per policy. A 5,000-character tool result is five units on every paid policy\n5. Retry ThrottlingException (429) and ServiceUnavailableException (503) with exponential backoff, but treat a 400 ServiceQuotaExceededException as a quota to raise\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, Amazon Bedrock Guardrails or OpenAI Guardrails?\n\nAmazon Bedrock Guardrails scores 74.8 (BB) on agent readiness against OpenAI Guardrails's 69.5 (B), and leads in 4 of 7 scored categories. OpenAI Guardrails leads on payments \u0026 pricing, maintenance \u0026 community and transparency \u0026 trust.\n\n### Can an agent call Amazon Bedrock Guardrails and OpenAI Guardrails without installing anything?\n\nAmazon Bedrock Guardrails has a hosted endpoint at https://bedrock-runtime.{region}.amazonaws.com/guardrail/{id}/version/{version}/apply. No hosted endpoint is listed for OpenAI Guardrails.\n\n### Are Amazon Bedrock Guardrails and OpenAI Guardrails open source?\n\nNo open-source release is listed for Amazon Bedrock Guardrails.
