Core Innovation
This paper introduces EmbeddingGemma, a lightweight embedding model that leverages encoder-decoder initialization and geometric embedding distillation to transfer knowledge from larger models. It enhances robustness and expressiveness with a spread-out regularizer and merges checkpoints from diverse optimized mixtures to improve generalizability. The model achieves state-of-the-art results with fewer parameters and maintains performance under quantization and truncation, enabling efficient deployment in resource-constrained environments.

Research Paper Overview
EmbeddingGemma: Powerful and Lightweight Text Representations
Summary
EmbeddingGemma is a lightweight open text embedding model based on the Gemma 3 language model family. It uses encoder-decoder initialization and geometric embedding distillation to capture knowledge from larger models. The model incorporates a spread-out regularizer to improve robustness and expressiveness and merges checkpoints from varied optimized mixtures to ensure generalizability. Evaluated on the Massive Text Embedding Benchmark across multilingual, English, and code domains, EmbeddingGemma (300M parameters) achieves state-of-the-art results, outperforming prior top models with fewer than 500M parameters and matching performance of models twice its size. It maintains performance even when quantized or truncated, making it suitable for low-latency and high-throughput applications such as on-device use. The model and ablation studies are released to the community to promote further research.
