Describe the audio.
NVIDIA Nemotron-3 Nano Omni Audio is a multimodal audio-language model for understanding and analyzing audio content. Provide an audio URL and an English prompt, and the model generates a text response for tasks such as audio description, spoken-content understanding, sound event analysis, and structured audio question answering.
Audio understanding with natural-language prompts Ask questions about an audio clip or request summaries, descriptions, and structured analysis in plain English.
Broad audio reasoning Analyze spoken content, sound events, acoustic context, and overall scene characteristics from uploaded audio.
Flexible response control
Adjust max_tokens, temperature, and top_p to balance response length, determinism, and creativity.
Optional system steering
Use system_prompt to guide output style, structure, or task behavior for more controlled results.
Reasoning mode options
Choose between no_think and think depending on your preferred response mode and workflow.
Production-ready API Suitable for audio analysis pipelines, multimodal assistants, content review systems, and automated media understanding workflows.
| Parameter | Required | Description |
|---|---|---|
| prompt | Yes | English text prompt sent to the model. |
| audio_url | Yes | URL of the audio to analyze. |
| system_prompt | No | Optional system prompt used to steer behavior, tone, or response style. |
| reasoning_mode | No | Reasoning mode: no_think (default) or think. |
| max_tokens | No | Maximum number of tokens to generate. Default: 1024. |
| temperature | No | Sampling temperature. Lower values are more deterministic. Default: 0.7. |
| top_p | No | Nucleus sampling probability mass. Default: 0.95. |

The endpoint returns a prediction id. Start polling the result endpoint around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. On completed, read output values from data.outputs. Examples for Nemotron 3 Nano Omni Audio below.

time.sleep(2)Nemotron 3 Nano Omni Audio is a NVIDIA model for AI inference, exposed as a REST API on WaveSpeedAI. NVIDIA Nemotron 3 Nano Omni is an open, efficient reasoning model for enterprise agentic workflows, built on a 30B A3B hybrid Transformer-Mamba MoE architecture. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID. Poll the result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates production-oriented Python, JavaScript, and cURL examples with timeouts, transient-error handling, and safe GET retries. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/nvidia/nvidia-nemotron-3-nano-omni-audio.
Nemotron 3 Nano Omni Audio starts at $0.010 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.
Key inputs: `prompt`, `audio_url`, `enable_sync_mode`, `max_tokens`, `reasoning_mode`, `system_prompt`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/nvidia/nvidia-nemotron-3-nano-omni-audio.
Median end-to-end generation time on WaveSpeedAI is around 6 seconds per request, based on recent successful runs. Queue time varies with global demand; live status is visible in the prediction record.
Commercial usage rights depend on the model's license, set by its provider (NVIDIA). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
