It is trained and tested on English only, each call checks one criterion, the 4.1 prompt format differs from 3.x, and IBM's watsonx.ai lists only the deprecated 3.0 model.\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### Granite Guardian\n\n1. Append the `\u003cguardian\u003e` block as the final user message, with the mode line, `### Criteria:` and `### Scoring Schema:`. Copy the strings from the model card, because no package builds them\n2. Use the no-think instruction for gating and parse `\u003cscore\u003e`. Think mode writes a reasoning trace first, and the card's examples allow up to 2,048 output tokens\n3. Treat `yes` as the criterion being met, which for built-in criteria means the risk is present. Treat a missing `\u003cscore\u003e` tag as a failed check\n4. Pass retrieved text through `documents=` and tool schemas through `available_tools=` in `apply_chat_template`, not inside the message text\n5. Under Ollama, set `num_ctx` in the request options. IBM's docs say the default context is short and long requests are truncated\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## Questions\n\n### Which is better for AI agents, Granite Guardian or OpenAI Moderation API?\n\nOpenAI Moderation API scores 71.3 (BB) on agent readiness against Granite Guardian's 60.1 (C), and leads in 5 of 7 scored categories.
