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**Mistral Moderation API.** Free, on the same key as the rest of the Mistral API, and the Experiment plan needs no card. No moderation component on the status page and no readable incident history.\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### Mistral Moderation API\n\n1. Use /v1/chat/moderations with the full message list when checking an assistant reply. The raw endpoint has no context\n2. Read category_scores and set your own threshold per category. The booleans use Mistral's cut-offs\n3. Pin mistral-moderation-2603. The 2411 model was retired on 31 March 2026\n4. Move to a paid workspace or zero retention if the text you screen shouldn't train models\n5. For a Mistral-hosted agent, set the moderation_llm_v2 guardrail with block_on_error true and skip the separate call\n\n## Questions\n\n### Which is better for AI agents, Granite Guardian or Mistral Moderation API?\n\nGranite Guardian scores 60.1 (C) on agent readiness against Mistral Moderation API's 58.4 (C), and leads in 4 of 7 scored categories. Mistral Moderation API leads on schema \u0026 documentation, agent ergonomics and transparency \u0026 trust.\n\n### Do Granite Guardian and Mistral Moderation API need an API key?\n\nGranite Guardian needs no key. Mistral Moderation API needs an API key.\n\n### Can an agent call Granite Guardian and Mistral Moderation API without installing anything?\n\nNo hosted endpoint is listed for Granite Guardian.
