Omnimodal VLM that processes text, images, video, and audio with only 3B active parameters

Nemotron-3-Nano-Omni is NVIDIA's Mixture-of-Experts model that unifies vision, audio, and language understanding in a single architecture. With 31B total parameters but only 3B active per token, it delivers omnimodal perception at a fraction of the compute cost of dense models: up to 9x throughput over comparable open alternatives.
On Mixpeek, Nemotron-3-Nano-Omni serves as a universal perception backbone: a single model call extracts understanding from video (up to 2 minutes), audio (up to 1 hour), images, and text. This eliminates the need for separate caption, transcription, and analysis models in complex pipelines.
Architecture
Mamba2-Transformer hybrid MoE. C-RADIOv4-H vision encoder + Parakeet-TDT-0.6B audio encoder + MoE language decoder. 31B total / ~3B active params per token. 256K context window. Processes up to 2 minutes of video or 1 hour of audio.
Mixpeek SDK Integration
// No extractor parameter takes a Hugging Face model id (checked against
// GET /v1/discovery/extractors, which returns 13), so Nemotron-3-Nano-Omni-30B-A3B-Reasoning-BF16 runs
// on your side and the output is upserted through POST
// /v1/namespaces/{namespace_id}/documents/upsert. On Enterprise the other
// path is to upload the weights instead: POST /v1/namespaces/{id}/models
// accepts the huggingface format and a custom plugin loads them.
