# Gemini Embedding 2 preview model

{% callout type="caution" %}
  Gemini Embedding 2 Preview (`gemini-embedding-2-preview`) is
  [deprecated](/docs/deprecations#embedding-deprecated-models). Effective
  November 6, 2026, API requests to `gemini-embedding-2-preview` route to
  [Gemini Embedding 2 (`gemini-embedding-2`)](/docs/models/gemini-embedding-2)
  at [Gemini Embedding 2 rates](/docs/pricing#gemini-embedding-2). Update your
  model string to `gemini-embedding-2`. `gemini-embedding-2` uses the same API
  schema, pricing, and embedding space, so no other code changes or vector
  re-indexing are needed.

{% /callout %}

Our first multimodal embedding model, providing efficient numerical mapping of
text, images, video, audio, and PDFs into a single unified embedding space. The
Gemini Embedding 2 model is best for cross-modal semantic search, document
retrieval, and recommendation systems that require fast, scalable similarity
calculations across large multimodal datasets.
