Amazon Titan Text Embeddings models

Amazon Titan Embeddings models include Amazon Titan Text Embeddings v2 and Titan Text Embeddings G1 model.

Text embeddings represent meaningful vector representations of unstructured text such as documents, paragraphs, and sentences. You input a body of text and the output is a (1 x n) vector. You can use embedding vectors for a wide variety of applications.

The Amazon Titan Text Embedding v2 model (amazon.titan-embed-text-v2:0) can intake up to 8,192 tokens or 50,000 characters and outputs a vector of 1,024 dimensions. The model is optimized for text retrieval tasks, but can also be optimized for additional tasks, such as semantic similarity and clustering.

Amazon Titan Embeddings models generate meaningful semantic representation of documents, paragraphs and sentences. Amazon Titan Text Embeddings takes as input a body of text and generates a (1 x n) vector. Amazon Titan Text Embeddings is offered via latency-optimized endpoint invocation for faster search (recommended during the retrieval step) as well as throughput optimized batch jobs for faster indexing. Amazon Titan Text Embeddings v2 supports long documents, however for retrieval tasks, it is recommended to segment documents into logical segments, such as paragraphs or sections.
