NVIDIA: Nemotron 3 Nano Omni (free)

NVIDIA: Nemotron 3 Nano Omni (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. A large 256K-token context window (≈384 pages of text) lets it take in whole books, large codebases, or lengthy transcripts in a single call. Beyond plain text it also accepts Audio, Image, Video input, so it can be applied to multimodal tasks rather than text alone. On Artificial Analysis's Intelligence Index it scores 15 (F grade), a useful proxy for its general reasoning strength relative to the other models tracked here. 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.
