What is Gemini Embedding?

Gemini Embedding is an advanced text embedding model from Google that transforms text into high-dimensional numerical vectors to capture its semantic and contextual information. Trained on the Gemini model, Gemini Embedding boasts powerful language understanding capabilities, supports over 100 languages, and ranks first in the Multilingual Text Embedding (MTEB) benchmark. The model is suitable for various scenarios, such as efficient retrieval, text classification, and similarity detection, significantly improving system efficiency and accuracy. Gemini Embedding supports input tag lengths of up to 8K and output dimensions of 3K, flexibly adjusting dimensions based on Matryoshka Representation Learning (MRL) technology to meet storage requirements. Gemini Embedding is now integrated into the Gemini API.

The main functions of Gemini Embedding

  • High-efficiency searchCompare the embedding vectors of queries and documents to quickly find relevant documents from massive databases.
  • Search Enhancement Generation (RAG)By combining contextual information, the quality and relevance of the generated text can be improved.
  • Text clustering and classificationGrouping similar texts, identifying trends and themes in the data, or automatically classifying text (such as sentiment analysis and spam detection).
  • Text similarity detectionIt identifies duplicate content and is used for deduplication or plagiarism detection on web pages.
  • Multilingual supportSupports over 100 languages, suitable for cross-language applications.
  • Flexible dimensional adjustmentAdjust the dimensions of the embedded vector according to requirements to optimize storage costs.
  • Long text embeddingIt supports input with up to 8,000 tags and can handle longer text, code, or blocks of data.

The technical principle of Gemini Embedding

  • Training based on Gemini modelBased on the Gemini model's deep understanding of language and context awareness, high-quality embedding vectors are generated.
  • High-dimensional embedding representationThe model outputs a 3K-dimensional embedding vector, which captures the semantic information of the text more precisely compared to traditional models.
  • Matryoshka Representation Learning (MRL)An innovative technology that allows users to truncate the original high-dimensional embedding vector according to their needs, reducing storage costs while maintaining the integrity of semantic information.
  • Context awarenessThe model can understand the contextual information of text and accurately capture semantics in complex multilingual environments.
  • Optimized input and outputIt supports inputs with up to 8,000 tags, can handle longer texts, and provides richer semantic representations based on high-dimensional embedding vectors.
