## Summary

NVIDIA introduced **Nemotron 3.5 Embed**, a set of open models designed to search documents containing charts, diagrams, and infographics as images. The release includes three embedding models (8B, 1B BF16, and 1B NVFP4), one reranking model (8B), and a parser (631M parameters) for converting document images into structured text. These models aim to address a common challenge in RAG systems: the loss of visual information when converting charts and tables to text via OCR, which makes them harder to search effectively.

The **Embed** models use a dense single-vector approach, allowing for easier integration into existing RAG pipelines. NVIDIA claims backward compatibility with previous-generation models of the same size, enabling reuse of text vectors and indices without full rebuilding. Performance benchmarks highlight improvements over prior versions, with the 8B model achieving competitive results on the **ViDoRe V3** benchmark. The models are licensed under **OpenMDW v1.1** (commercial use allowed) and **Apache 2.0** for base components, while inference containers (NIM) follow NVIDIA’s proprietary licensing terms.

## Key points

- Nemotron 3.5 Embed includes three embedding models (8B, 1B BF16, 1B NVFP4) and one reranking model (8B) for chart/document search
- Models support text, images, or combined inputs, outputting fixed-length vectors (4,096 for 8B, 2,048 for 1B) with adjustable dimensions
- NVIDIA claims backward compatibility with prior-generation models of the same size for text vector reuse

## Why it matters

This release enables more accurate search in visually dense documents like financial reports or technical specs, reducing reliance on OCR and improving retrieval for enterprise RAG systems.
