Gemini Embedding 2 is Google's first natively multimodal embedding model that maps text, images, video, audio and documents into a single embedding space, enabling multimodal retrieval and classification across different types of media and it’s available now in public preview.
Gemini Embedding 2 is Google's first natively multimodal embedding model, designed to map text, images, video, audio, and documents into a single embedding space.
Most embedding pipelines today are fragmented... developers often need separate models and preprocessing steps (like audio transcription or image captioning) before generating embeddings. Gemini Embedding 2 simplifies this by handling multiple modalities directly and enabling multimodal retrieval, classification, and semantic search from one unified model.
Key features:
Multimodal embeddings for text, images, video, audio, and PDFs
Up to 8192 tokens for text, 6 images per request, 120s video, and 6-page PDFs
Native audio embeddings without transcription
Supports 100+ languages
Interleaved multimodal inputs (e.g., text + image together)
Flexible embedding dimensions with Matryoshka Representation Learning (3072 → 768)
Why this matters: Developers can build RAG systems, semantic search, sentiment analysis, clustering, and multimodal retrieval much more easily with a single embedding model that understands different media types together.
Who it’s for: AI developers, ML engineers, and teams building search, assistants, knowledge bases, and multimodal AI applications.
If you’re building the next generation of multimodal AI experiences, this is definitely worth exploring.

The native audio embeddings without transcription step is the part I want to test first. We log food via voice in FuelOS and always pre-transcribe before any semantic matching, which adds latency and a failure point. Does the audio embedding quality hold up for short, noisy clips (5-15 seconds) or is it optimized more for longer-form content?

A natively multimodal embedding model that maps text, images, video, and audio into the same space is a big deal. Most embedding approaches still treat modalities separately, which creates friction when you want to do cross-modal search or retrieval. This should make building multimodal RAG systems much more straightforward.
