NVIDIA released Nemotron 3 Embed, a collection of open embedding models for retrieval-augmented generation and agentic systems. The 8B model ranks #1 on the RTEB benchmark with an average NDCG@10 score of 78.46, and the 1B-NVFP4 variant achieves 99.5% accuracy retention of its BF16 parent while delivering up to 2x higher throughput on Blackwell hardware. The release includes three checkpoints supporting 32,768-token sequence lengths across multilingual tasks, with the smaller models created through neural architecture search pruning and knowledge distillation from the larger 8B teacher model.
