Nemotron 3.5 Embed 8B BF16
NVIDIA embedding model with 8.38B parameters, released on October 20, 2026. It vectorizes text, page images or both for retrieval with text queries. It freezes the Nemotron 3 Embed 8B tower and adds vision through Pixtral. It retains that predecessor’s text embedding space; it produces 4,096-dimensional vectors, not conversational responses.

Semantic search and RAG over reports, tables, charts and infographics. NVIDIA reports text evaluation in 34 languages and visual evaluation in 18; this coverage is not a universal guarantee. Use the exact checkpoint identifier and official query and document prefixes. The examples support batch inference on self-hosted infrastructure.
The documented limit is 32,768 combined tokens, although the internal configuration declares more positions. Images default to a longest edge of 1,120 pixels, expandable to 1,540. Review any trust_remote_code before execution. The Transformers examples with Flash Attention 2 require version 5.20.0; vLLM 0.32.0 uses a separate environment with Transformers below 5.20.0. Inferama has not run inference.

05 / EVALUATIONS
How to read the results
“
The official model card mentions ViDoRe V3 and MIRACL-VISION with NDCG@10, but publishes no verifiable numerical scores for this checkpoint. We do not transfer predecessor results or invent ranking positions. Inferama evaluation is pending. For reproduction, retain revision, dataset, languages, candidates, resolution, dimensions, normalization, hardware and latency; compare retrieval and reranking as separate stages.
i ViDoRe V3 and MIRACL-VISION documented; no verified numerical scores.
Inferama only highlights a “best result” when the metric, test set, configuration, and date allow for an equivalent comparison. The supplier's figures are presented as claims from its own source.
