Nemotron 3.5 Content Safety is a 4B-parameter guardrail model from NVIDIA, fine-tuned from Gemma-3-4B. It checks both what users send to a language or vision model and what the model answers, and returns a safe or unsafe verdict for each, the safety categories involved and, optionally, its reasoning. It understands text and images, covers 12 languages and reads up to 128K tokens.

It accepts text and image input and returns text, and supports streaming. Nemotron 3.5 Content Safety is commonly used for prompt and response moderation, content classification, safety pipelines and enterprise AI guardrails. Hormouz serves it behind an OpenAI-compatible API: point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs without changes.

Pricing is usage-based: $0.2 per million input tokens and $0.2 per million output tokens. There is no fixed monthly fee, and you pay only for the tokens you use. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
