OAuth only, and a template must exist in the same location as the endpoint before the first call.\n\n**LlamaFirewall.** One `scan()` call runs several checks on the owner's machine and returns a short typed result. The last PyPI release is 1.0.3 from 29 May 2025, and its Prompt Guard loader imports a `huggingface_hub` class that current versions no longer export, so a fresh install needs older pins. The classifier weights also need Meta's manual approval.\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### LlamaFirewall\n\n1. Pin `huggingface_hub` below 1.0 and a matching `transformers` 4.x before importing the Prompt Guard scanner from the 1.0.3 wheel, or install from main\n2. Get access to `meta-llama/Llama-Prompt-Guard-2-86M` and set a Hugging Face token first. Without one the loader prompts for a login and a headless run stalls\n3. Call `scan_async` inside a running event loop. `scan()` wraps `asyncio.run` and fails there. `scan_async` returns score 0.0 and reason `default` on every allow\n4. Split text longer than 512 tokens yourself before a Prompt Guard scan. The library truncates and does not chunk\n5. Do not feed a block `reason` back to the model. The Prompt Guard reason quotes the full scanned text, and the hidden ASCII reason decodes the hidden payload\n\n## Questions\n\n### Which is better for AI agents, Google Cloud Model Armor or LlamaFirewall?\n\nGoogle Cloud Model Armor scores 77.9 (BB) on agent readiness against LlamaFirewall's 50.8 (D), and leads in 6 of 7 scored categories. LlamaFirewall leads on payments \u0026 pricing.\n\n### Can an agent call Google Cloud Model Armor and LlamaFirewall 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 LlamaFirewall.\n\n### Are Google Cloud Model Armor and LlamaFirewall open source?\n\nNo open-source release is listed for Google Cloud Model Armor. LlamaFirewall is open source (MIT (library). The Prompt Guard 2 weights it downloads are under the Llama 4 Community Licence).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/google-model-armor-vs-llamafirewall.json, and with the fewest tokens: https://www.anchorterminal.com/compare/google-model-armor-vs-llamafirewall.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"google-model-armor\", \"b\": \"llamafirewall\"}`.
