The weights have not changed since 29 April 2025, download access needs Meta's manual approval, and the licence withholds the grant from individuals and companies based in the European Union.\n\n**Prisma AIRS AI Runtime Security API.** A public OpenAPI document, ten detection types in one call, tool-call scanning, a remote MCP server, rotating API keys and OAuth roles suit teams already on Strata Cloud Manager. Access needs Software NGFW credits bought through sales, with no public price, trial or self-serve signup, and payloads flagged malicious are kept for up to 10 years.\n\n## Before you call either\n\n### Llama Guard 4\n\n1. Request access on the Hugging Face page before anything else. Approval is manual, and the form cannot be edited after submission\n2. Send only the user turn to check an input, and the user turn plus the model's answer to check an output. The template picks the role from the message count\n3. Parse the first line for `safe` or `unsafe` and the second for category codes. Set `max_new_tokens` to about 10 and turn sampling off\n4. Do not send an image with no text. Meta says the model is not an image-only classifier, and S14 is skipped when an image is present\n5. Pair it with a prompt-attack detector. The card says the model can itself be moved by adversarial or injected text\n\n### Prisma AIRS AI Runtime Security API\n\n1. Send `x-pan-token` and an `ai_profile` with `profile_name` or `profile_id` on every scan. Both come from Strata Cloud Manager, and a key works only in its own region\n2. Put earlier turns first in `contents`. Only the last element is scanned, and the rest is context\n3. Read `action` (allow or block) and `category`, then check `timeout` and `error`, because a detector that failed is reported in `errors` with a 200\n4. Keep synchronous requests under 2 MB and asynchronous ones under 5 MB and 25 items, and fetch at most 5 scan or report IDs a call, 10 calls a minute\n5. For MCP, connect to `/mcp` on the regional host with `x-pan-token` and `x-pan-profile` headers, and call `pan_inline_scan` yourself before and after generation\n\n## Questions\n\n### Which is better for AI agents, Llama Guard 4 or Prisma AIRS AI Runtime Security API?\n\nPrisma AIRS AI Runtime Security API scores 62.8 (B) on agent readiness against Llama Guard 4's 49.1 (D), and leads in 5 of 7 scored categories.
