NVIDIA Nemotron Nano 9B V2 is a 9B-parameter language model trained from scratch by NVIDIA, available free on OpenRouter. Designed as a unified model for both reasoning and non-reasoning tasks — it generates a reasoning trace before delivering a final answer, with the ability to skip intermediate reasoning via system prompt configuration. This makes it a single model that handles both chain-of-thought and direct-response tasks. 131K context window. Text-only. Also available directly on NVIDIA NIM. OpenAI-compatible. Free tier: 200 RPD.
