 are designed for multimodal applications. Gemini models accept prompts that include, for example, text and images, and then return a text response. Gemini also supports function calling, which lets developers pass a description of a function and then the model returns a function and parameters that best matches the description. Developers can then call that function in external APIs and services.

: This advanced model boasts a large context window, handling up to 1 million tokens and allowing for nuanced understanding of complex prompts and generation of comprehensive responses.

: These models are perfect for natural language tasks, multi-turn conversations, and code generation. They also offer the ability to incorporate images, PDFs, and videos into your prompts, making them versatile for multimodal applications.

: As Google's most capable multimodal models, these are optimized for intricate tasks involving instruction understanding, code generation, and reasoning. They offer support for multiple languages and are currently available to a select group of customers.

Embeddings for Text (textembedding-gecko) is the name for the model that supports 

. Text embeddings are a NLP technique that converts textual data into numerical vectors that can be processed by machine learning algorithms, especially large models. These vector representations are designed to capture the semantic meaning and context of the words they represent.

There are a few versions available for embeddings. textembedding-gecko@003 is the latest stable embedding model with enhanced AI quality, and textembedding-gecko-multilingual@001 is a model optimized for a wide range of non-English languages.

 generates dimension vectors (128, 256, 512, or 1408 dimensions) based on the input you provide. This input which can include any combination of text, image, or video. The embedding vectors can then be used for other subsequent tasks like image classification or content moderation.

The text, image, and video embedding vectors are in the same semantic space with the same dimensionality. Therefore, these vectors can be used interchangeably for use cases like searching images by text, or searching video by image.

 develops and distributes compact, high-performance Search Foundation models for multilingual text and image processing.

 constructs semantic embedding vectors for texts in 89 languages and allows users to select the output embedding size from a maximum of 1024 dimensions down to 64. These compressed embeddings are nearly equal to the full embeddings in performance, but they are dramatically smaller and our experiments show they speed up search applications proportionately.

This model also provides task-specialized embeddings for classification, clustering, and semantic similarity, while supporting asymmetric retrieval by letting users encode search queries and targets in different, optimized ways.

 provides multimodal embeddings for texts and images, enabling cross-modal applications like image search, but also brings image support to typical text AI applications like semantic similarity, classification, and clustering. By producing the same embedding vectors for texts and images, it acts as a drop-in for any vector-based application framework supporting text.

provides high-quality reanalysis of semantic matches, especially in text-based information retrieval, compensating for the limitations of semantic embedding vectors by analyzing the semantics of texts more closely. Rerankers are typically used in retrieval applications to enhance precision. 

Together with Elasticsearch, Jina AI's search foundation models create powerful search applications - encode your text and images as compact embeddings, store them efficiently in Elasticsearch, and enhance result relevance through reranking, enabling high-performance multilingual and multimodal search at scale.
