Nemotron 3 Nano Omni 30B A3B Reasoning

Function calling Reasoning Vision Reasoning

Nemotron 3 Nano Omni is an open multimodal model built on a hybrid Mixture-of-Experts (MoE) architecture, engineered for high efficiency and strong accuracy across image, video, audio, and text inputs.

What it's best for

Best for multi-step problems where the model benefits from working through its chain of thought: maths, analysis, planning and agentic loops. Reasoning models produce (and bill for) more output tokens than plain chat models, so use them where the extra thinking pays for itself. It supports function calling, so it can drive tools and agent workflows.

Pricing

Prices updated daily — last generated 2026-07-08.

Billing is metered per request in GBP on the same monthly invoice as your apps — no subscription, no minimum. We list every model once, at the cheapest route we can serve it on; if we have to fail over to a more expensive route, we absorb the difference and your price does not change.

Where your data is processed

Requests to Nemotron 3 Nano Omni 30B A3B Reasoning are routed to a vetted partner provider and processed on that provider's infrastructure — they leave our infrastructure, and the UK-residency guarantee that applies to our UK-hosted models does not apply here. We hold the provider credentials server-side and route on cost and availability. If you need prompts that never leave our own infrastructure, use one of our UK-hosted models.
