Fine-tuned reranking model for multilingual, cross-lingual text question-answering retrieval, with long context support.
Overview
The NVIDIA NeMo Retriever Llama3.2 reranking model is optimized for providing a logit score that represents how relevant a document(s) is to a given query. The model was fine-tuned for multilingual, cross-lingual text question-answering retrieval, with support for long documents (up to 8192 tokens). This model was evaluated on 26 languages: English, Arabic, Bengali, Chinese, Czech, Danish, Dutch, Finnish, French, German, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Norwegian, Persian, Polish, Portuguese, Russian, Spanish, Swedish, Thai, and Turkish.
The reranking model is a component in a text retrieval system to improve the overall accuracy. A text retrieval system often uses an embedding model (dense) or lexical search (sparse) index to return relevant text passages given the input. A reranking model can be used to rerank the potential candidate into a final order.
This model is ready for commercial use.
Highlights
- Reorders citations by how well they match a query. This is a key step in the retrieval process, especially when the retrieval pipeline involves citations from different datastores that each have their own algorithms for measuring similarity.
- Production-ready information retrieval pipeline with enterprise support

Dimensions summary
You pay by the host hour for running this reranking model on a chosen SageMaker instance. Pricing splits into two inference modes: batch and real-time. Batch mode runs on eight ml.g5 instance sizes. Real-time mode covers a wider set, including ml.g5, ml.g6, ml.g6e, ml.p4d, ml.p4de, and ml.p5 instances. Within each family, larger instance sizes carry more GPU and compute capacity. Your rate depends on the instance type and size you select, plus the underlying AWS infrastructure cost. You are billed only for the hours each instance runs.
Top-of-mind questions for buyers
One HostHrs unit is one hour that a single chosen SageMaker instance runs the reranking model. You are billed per running host per hour. Counting starts when the instance is active and stops when it is no longer running. The rate depends on the instance type and size you select.
Batch mode runs on eight ml.g5 instance sizes and processes grouped requests. Real-time mode serves live requests and covers ml.g5, ml.g6, ml.g6e, ml.p4d, ml.p4de, and ml.p5 instances. Both bill by the host hour. Real-time offers more instance families, so you can match hardware to workload demand.
Software charges apply per running host per hour. When an instance is fully stopped, it does not run the model, so software host-hour charges stop. Underlying AWS infrastructure fees, such as storage, may still apply while resources exist. You pay only for hours the instance actively runs.
