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**NVIDIA NeMo Guardrails.** Apache-2.0, 7,200 stars and nine releases between 9 October 2025 and 16 September 2026. Usage telemetry and a heartbeat every 10 minutes to NVIDIA by default.\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### NVIDIA NeMo Guardrails\n\n1. Set NEMO_GUARDRAILS_NO_USAGE_STATS=1 before import unless you want deployment metadata sent to NVIDIA every 10 minutes\n2. Use IORails for plain input and output checks. LLMRails and Colang are for dialogue flows a tool-calling agent rarely needs\n3. Pin nemoguardrails==0.24.1. 0.24.0 changed message passing to messages= and removed inline config from /v1/checks\n4. Call /v1/checks with a config_id loaded on the server and branch on the RailOutcome\n5. Put the server behind your own gateway. It has no auth or rate limiting\n\n## Questions\n\n### Which is better for AI agents, Granite Guardian or NVIDIA NeMo Guardrails?\n\nNVIDIA NeMo Guardrails scores 68.4 (B) on agent readiness against Granite Guardian's 60.1 (C), and leads in 4 of 7 scored categories.\n\n### Can an agent call Granite Guardian and NVIDIA NeMo Guardrails without installing anything?\n\nNo hosted endpoint is listed for Granite Guardian. No hosted endpoint is listed for NVIDIA NeMo Guardrails.\n\n### Are Granite Guardian and NVIDIA NeMo Guardrails open source?\n\nNo open-source release is listed for Granite Guardian.
