NVIDIA AI Releases Nemotron 3 Embed: An Open Embedding Collection Whose 8B Checkpoint Ranks #1 on RTEB

NVIDIA released Nemotron 3 Embed, an open embedding collection with three checkpoints, on July 15-16, 2026. The 8B checkpoint ranks #1 on the RTEB benchmark with a 78.46 average NDCG@10, while the 1B and NVFP4 variants achieve high efficiency with minimal accuracy loss. The models support 32,768-token inputs under the OpenMDW-1.1 license.

NVIDIA released Nemotron 3 Embed on July 15 and 16, 2026. The collection has three open checkpoints: Nemotron-3-Embed-8B-BF16, Nemotron-3-Embed-1B-BF16, and Nemotron-3-Embed-1B-NVFP4. The 8B ranks 1 on RTEB at 78.46 average NDCG@10. The 1B came from ModelOpt NAS pruning plus COS+MSE distillation from the 8B teacher. NVFP4 retains 99%+ of BF16 retrieval accuracy at up to 2x Blackwell throughput. All three run 32,768-token inputs under OpenMDW-1.1.
