NVIDIA's New Embedding Models Deliver Massive Score Boosts

tomaarsen · x · 2026-07-17

NVIDIA's Nemotron-3-Embed-1B utilizes an unusual compression pipeline: starting from a 3B parent, it undergoes NAS pruning to 2B via NVIDIA ModelOpt, followed by distillation to 1.14B using an 8B teacher with cosine + MSE loss.

The author shares retrieval evaluation results: on 16 RTEB tasks, Nemotron-3-Embed-8B achieved an average NDCG@10 of 78.46, while the 1B version scored 72.38. The previous generation llama-nemotron-embed-1b-v2 scored only 60.47 at the same size, indicating an 11.9-point improvement for the 1B model. Similar gains were observed on MMTEB Retrieval (71.04 vs 59.58).
