State-of-the-art text embedding model with the best general-purpose and multilingual retrieval quality. 32K context length.
Overview
Text embedding models are neural networks that transform texts into numerical vectors. They are a crucial building block for semantic search/retrieval systems and retrieval-augmented generation (RAG) and are responsible for the retrieval quality. voyage-3-large is a state-of-the-art general-purpose and multilingual embedding model that ranks first across eight evaluated domains spanning 100 datasets, including law, finance, and code. It outperforms OpenAI-v3-large and Cohere-v3-English by an average of 9.74% and 20.71%, respectively. Enabled by Matryoshka learning and quantization-aware training, voyage-3-large supports smaller dimensions and int8 and binary quantization that dramatically reduce vectorDB costs with minimal impact on retrieval quality. Latency is 90 ms for a single query with at most 100 tokens, and throughput is 12.6M tokens per hour at $0.22 per 1M tokens on an ml.g6.xlarge.

Input data descriptions
The following table describes supported input data fields for real-time inference and batch transform.
Field name | Description | Constraints | Required |
|---|---|---|---|
input | A single text string, or a list of texts as a list of strings. | Type: FreeText
Limitations: The maximum tokens for each text is 32K, the maximum length of the list is 128, and the total number of tokens in the list is at most 32K. | Yes |
input_type | Type of the input text. Default to null. Other options: "query", "document". | Default value: null
Type: FreeText | No |
truncation | Whether to truncate the input texts to fit within the context length. - If True, over-length input texts will be truncated to fit within the context length. - If False, an error will be raised if any given text exceeds the context length. | Default value: True
Type: Categorical
Allowed values: True, False | No |
output_dimension | The number of dimensions for resulting output embeddings. Options: 2048, 1024, 512, 256, `null`. If `null`, then output dimension is 1024. | Default value: null
Type: Integer | No |
output_dtype | The data type for the resulting output embeddings.
