About the model

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

#### Finding the relevant page from a question

Llama Nemotron Embed VL 1B v2 was developed by NVIDIA to retrieve material that helps answer a question. The query is text. Ailoot's current catalogue presents text input for the model: the question and material are encoded as text. The manufacturer also describes a document as a page image or an image together with extracted text. These visual variants require a separate method supporting images. With the appropriate input, the model represents tables, charts and infographics in a shared vector space.

This retrieval is suited to question-answering assistants over large document collections, internal reference material and research material. Encoding produces a numerical vector. The retrieved page or passage can then be supplied to a model that forms an answer: Embed VL itself performs the context-retrieval stage.

#### The manufacturer's document options

- A text document: an individual section, passage or already recognized page text.
- An image: a complete page with its text, tables and graphic elements.
- An image with text: a page's visual appearance and textual content combined in one representation.

Query and document are encoded independently. A collection can therefore be processed in advance, with vectors stored alongside source pages, and only the query vector computed for a new question. Vector similarity helps select material by meaning. The text roles of queries and documents differ, which needs to be preserved when preparing data.

#### Representation size and input length

Each input becomes one vector of up to 2048 numbers. Text mode uses a budget of 8192 tokens. The manufacturer's visual method combining an image and text describes a shared budget of 10,240 tokens including both parts; this is not the text limit of Ailoot's method. The image is split into patches: the described configuration permits up to six patches and a downscaled copy of the whole page, totaling around 1792 visual tokens. Long text needs to be divided or shortened.

The language component is based on Llama 3.2 1B and the visual component on SigLIP2. They are combined into an encoder that averages input-token representations and returns a single vector. Contrastive training moves a question closer to the appropriate page and farther from irrelevant material. Retrieval remains probabilistic: vector proximity does not guarantee that the selected passage contains the correct answer.
