Gemini Embedding 2

Gemini Embedding 2 is Google's embedding generation model that's ideal for complex retrieval and analytics tasks.

Gemini Embedding 2 accepts multimodal inputs to generate 3072-dimensional vectors. It accepts images, text, documents, audio, and video inputs and semantically maps the generated vectors into a unified semantic space. This lets you perform tasks, such as searching for an image based on a text description.

Gemini Embedding 2 introduces several features to optimize embedding quality and flexibility:

  • Custom task instructions: By specifying task instructions (for example, task:code retrieval or task:search result) optimize the embeddings for the intended relationships and retrieve more accurate results for the specific goal.

  • Adjustable result size: The model generates a 3072-dimensional float vector, by default. However, you can retrieve a smaller dimensional output by specifying the output_dimensionality parameter.

  • Document OCR: Read OCR from document inputs.

  • Audio track extraction: Extract audio tracks from video inputs and interleave them with video frames.
