Thinking levels:

Nemotron 3.5 Lightning is an open model from NVIDIA: a 30B mixture-of-experts with only 3B parameters active per token. It is built for high-throughput agent workloads and for specialised tasks where a team customises the model for its own domain. Its price is very low, which suits pipelines that make many calls.

It accepts text input and returns text, and supports tool calling, structured JSON output and streaming. Nemotron 3.5 Lightning is commonly used for high-volume agents, classification and extraction, domain-specific assistants and cheap sub-agents. 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: $0.06 per million input tokens and $0.16 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.
