NVIDIA: Nemotron 3 Ultra (free)
🇺🇸 NVIDIA · Nemotron 3
Overview
NVIDIA: Nemotron 3 Ultra (free) is a large language model API from NVIDIA, part of its Nemotron 3 model family. It is currently routed free of charge on OpenRouter, which makes it well suited to prototyping and high-volume experimentation where per-token cost would otherwise dominate. An exceptionally large 1M-token context window (≈1,500 pages of text) means entire repositories or document collections can be processed without chunking. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.
