Gemini Embedding 2
State-of-the-art multimodal embedding model
Maps text, images, videos, audio, and documents into a single, unified embedding space to capture the semantic relationships across data
Capabilities
Gemini Embedding 2 enables enhanced understanding of multimodal data for downstream tasks, from retrieval and classification to clustering and recommendations
Slide 1 of 5
Natively multimodal
Understands different modalities and interleaved inputs, eliminating the need for separate embedding models and reducing pipeline complexity.
Contextual grounding for RAG
Anchors agents and applications by providing the deep context necessary for accurate, grounded retrieval.
Semantic alignment across modalities
Powers multimodal search and clustering without requiring users to have cross-modality aligned data.
Powerful performance, minimal footprint
Supports large input length and uses Matryoshka Representation Learning for flexible output dimensions that maintain accuracy at smaller sizes.
Multilingual understanding
Captures conceptual meaning in over 100 languages, resulting in more consistent representations for cross-lingual tasks.
Performance
State-of-the-art results on a range of cross-modal benchmarks

“Empowering our teams to seamlessly search past and present content has increasingly driven us to vector search. While initially seeing great results with traditional large text embeddings (3,072 dim), crowding in vector space quickly took over; the right results couldn't reliably surface their way up from the noise. Gemini's new Embedding 2 model completely changed the game. Text queries can now pinpoint untranscribed micro-expressions, and we can even leverage existing media, such as a photo or B-roll clip, as the search input to instantly retrieve matching video assets. This propelled our text-to-video Recall@1 rate to 85.3%.”

“We chose Gemini Embedding 2 to help legal professionals find critical information during the discovery process in litigation – a highly technical challenge in a high-stakes setting, and one Gemini excels at. In our most recent tests, Gemini's multi-modal embedding model improves precision and recall across millions of records, while unlocking powerful new search functionality for images and videos. For legal professionals, these new capabilities open up entirely novel ways to quickly understand case materials in even the largest matters.”

“Gemini Embedding 2 is the foundation for Sparkonomony’s Creative Economic Equality Engine. Its native multi-modality slashes our latency by up to 70% by removing LLM inference and nearly doubles semantic similarity scores for text-image and text-video pairs-leaping from 0.4 to 0.8. This powers our proprietary Creator Genome to index millions of minutes of video, alongside images and text, with unprecedented precision—unlocking unbiased brand collaborations and democratizing economic success for every creator.”

“The API continuity is excellent. Gemini Embedding 2 drops right into our existing workflow with minimal changes. We're testing new ways to embed text-based conversational memories together with audio and visual embed-dings, especially assistant question-and-answer pairs, and seeing a 20% lift in top-1 recall for our personal wellness app.”
