Introducing EmbeddingGemma: The Best-in-Class Open Model for On-Device Embeddings

EmbeddingGemma is an innovative open embedding model designed for efficient on-device AI applications, boasting state-of-the-art performance for its size with 308 million parameters. This model is specifically tailored for use in environments that require privacy and offline capabilities, such as mobile devices, by enabling tasks like Retrieval Augmented Generation (RAG) and semantic search without needing an internet connection. With its foundation in the Gemma 3 architecture, EmbeddingGemma supports over 100 languages and is capable of operating with less than 200MB of RAM due to quantization techniques. It offers flexible output dimensions and a 2K token context window, making it suitable for a variety of devices and use cases. EmbeddingGemma integrates seamlessly with popular tools such as sentence-transformers and transformers.js, facilitating easy adoption for developers. By leveraging Matryoshka Representation Learning, it allows for multiple embedding sizes, optimizing both quality and performance. The model underscores its utility in providing high-quality text embeddings crucial for on-device applications, ensuring secure and efficient processing of sensitive data while enabling new capabilities like offline personal file searches and customized chatbots.
