About the model

This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.

#### Understanding different types of material

Nemotron 3 Nano Omni was created by NVIDIA for question answering, summaries, speech transcription and document analysis. At the model level, text, images, video and audio are combined. Output is text: the model describes content, answers questions and produces transcripts.

Analysis of meeting recordings, retrieval and description of events in video material, and analysis of business and scientific documents are provided. Interface understanding and recognition of text in images allow it to be used in agentic tasks involving a visual working environment.

#### Language foundation and encoders

The foundation is a hybrid Mamba-2 and Transformer model with expert layers: around 31 billion parameters in total and approximately 3 billion active per token. A separate visual encoder processes images and frames, and a speech encoder handles the audio signal. Shared context reaches 256 thousand tokens. Declared language support is English.

#### Input formats

The manufacturer's card lists text strings, RGB PNG and JPEG images, MP4 video, and WAV or MP3 audio. For video, clips of up to two minutes are described; frame sampling rate depends on resolution. For 1080p, an option of up to one frame per second and 128 frames is specified; for 720p, up to two frames per second and 256 frames. Audio duration of up to one hour and sample rates from 8 kHz are specified.

A document page can be supplied as an image for analysis: this differs from submitting an unprocessed PDF. Data supported for a specific request depends on the selected input method.

#### Reasoning and text results

A reasoning mode and a mode for direct instruction execution are provided. For long documents and complex multimodal analysis, the manufacturer uses reasoning with a controlled budget. For speech recognition, it recommends direct mode.

The model supports JSON text, tool calls and transcription with word-level timestamps. Recommended generation lengths concern task settings; they do not establish a universal maximum number of output tokens.

Practical task

### Summarize an English meeting transcript

Technical example in English

```
Summarize an English meeting transcript

Summarize this transcript for the project owner. Erin: “The test build passed, but the release checklist is incomplete.” Sam: “I will finish the checklist tomorrow; deployment still needs approval.” Return the completed fact, the promised action with owner and the remaining approval. Preserve the distinction between a test build and deployment.
```

#### Expected result

```
A three-part meeting note: completed work, owner action and unresolved approval.
```

#### Check the result

```
Check that a passed test build is not rewritten as a deployed release and that Sam’s promise remains future work.
```

### Receive and save results

#### Ailoot · OpenAI Chat

json or SSE

##### Keep all completed results

Keep every complete returned response, file and content part.

Keep every choice and its content/tool calls/reasoning. In SSE assemble deltas by choice/tool index, retain the final finish reason and usage.

##### If the original response needs checking

Keep request/response IDs and headers. No generic text job retrieval URL is supplied.
