Embed 5 is Cohere's most powerful embedding family yet, delivering frontier retrieval on complex enterprise data that matches or exceeds the competition and makes major gains on Embed 4.
Overview
Every AI application is only as good as the information it retrieves. Embed 5 is Cohere's most powerful embedding family yet, turning reports, scanned pages, charts, contracts, and code into searchable representations of meaning, so the right content surfaces even when the words don't match. That means fewer more accurate answrs, fewer wasted LLM tokens, and better end user experiences.
Embed 5 Fast is for workloads where response time matters. Despite its compact size, it rivals or beats much larger models in finance, complex-document, and multimodal retrieval. Screen payments for fraud as they're authorized, refresh product results with every keystroke, route tickets instantly, or guide support agents during live calls.
Key specifications:
- 128K-token context window for long documents
- Embeds text, image, and mixed text-and-image pages
- Supports 100+ languages, including cross-language search
- Adjustable vector size dimensions (Matryoshka Representation Learning) with float, int8, and binary outputs
- Shared embedding space with Embed 5 Pro
- Works with OpenSearch, LangChain, Pinecone and more
Highlights
- Where pace meets performance. Embed 5 Fast is the highest-performing embedding model in its size class, built for interactive search, agent loops, and high-volume query traffic. Like Pro, Embed 5 Fast excels with professional, multimodal documents and regularly outperforms competitor flagship models at a fraction of the cost.
- Breakthrough embeddings speed.* Embed 5 Fast is optimized for low-latency, high-throughput retrieval. In our benchmarks, it delivered up to 71% lower p50 latency, 47% lower p99 latency, and 3.1x higher document throughput than Embed 5 Pro.
- Built to scale with Embed 5 Pro. Embed 5 Fast shares an embedding space with Embed 5 Pro, so both models work against the same vector index. That means one index to store, secure, and maintain, with no costly re-embedding as needs change. Route latency-sensitive traffic to Fast and quality-critical queries to Pro, or shift workloads between them over time. Balance performance, speed, and cost on one consistent retrieval setup.

Inputs
- Summary
This model accepts JSON requests that specifies a content object which can contain a list of texts, a list of data urls of a base64 encoded images or combination. This model supports interleaved images and texts in the same request. { ""content"": [ { ""type"": ""text"", ""text"": ""Look at my awesome car!"" }, { ""type"": ""image"", ""image"": f""data:image/png;base64,{base64_image}"" }, { ""type"": ""text"", ""text"": ""Do you want to buy it?"" }, ]
- Input MIME type
- application/json
{ ""content"": [ { ""type"": ""text"", ""text"": ""Look at my awesome car!"" }, { ""type"": ""image_url"", ""image_url"": ""data:image/png;base64,{base64_image}"" }, { ""type"": ""text"", ""text"": ""Do you want to buy it?"" } ], ""input_type"": ""search_document"", “embedding_types”: [""int8”], ""max_tokens"":8000, “output_dimensions”: 1024 }
Cohere's embedding models do NOT support batch transform.
Input data descriptions
The following table describes supported input data fields for real-time inference and batch transform.
Field name | Description | Constraints | Required |
|---|---|---|---|
inputs | A list of dicts with the key "content", which is a list whose type is either text or image_url. If type='text', there is a text key with a string. If type=image_url, it's a data URL formatted base64-encoded image and an image key. The max pixels per image is 2,458,624, the max memory size of a single request is 20 MB, and inputs objects can have at most 96 inputs. The inputs object can have a maximum of 800,000 tokens, calculated as follows: 1) For each image: image pixels / 784 (pixels per token) = tokens 2) For each text: text tokens 3) Total inputs object = for each input, the sum of (1) and (2). | The input data type is categorical. The default value is none. | No |
texts | An array of strings for the model to embed. Maximum number of texts per call is 96. If you are using the texts parameter, you cannot use the images parameter in the same call. The input data type is text. | N/A | No |
images | An array of base64-encoded data URLs as strings to embed.
There is no limit on the number of images per call. | The combined size of all images in the request must be at most 20MB. | No |
input_type | Specifies the type of input passed to the model.
"search_document": Used for embeddings stored in a vector database for search use-cases.
"search_query": Used for embeddings of search queries run against a vector DB to find relevant documents.
"classification": Used for embeddings passed through a text classifier.
"clustering": Used for the embeddings run through a clustering algorithm.
"image": Used for embeddings with image input. | Value must be one of: search_document, search_query , classification, clustering, or image | Yes |
embeddings_type | Specifies the types of embeddings you want to get back. Not required. If unspecified, defaults to float . | Input must be one of: float , int8 , uint8, binary, ubinary, base64 | No |
output_dimension | Specifies the length of the output dimensions of the embeddings vector. Not required. If unspecified, returns 1024 dimensions per embedding vector. | Input data type is categorical. If categorical is chosen: {256, 512, 768, 1024, 1536, 2048}. The default value is 1024. | No |
max_tokens | The maximum number of tokens considered for each input object before it is truncated; the default for this model is set at 128,000 tokens. | The input data type is integer. | No |
truncate | One of NONE, START, or END to specify how the API will handle inputs longer than the maximum token length. Passing START will discard the start of the input. END will discard the end of the input. In both cases, input is discarded until the remaining input is exactly the maximum input token length for the model. If NONE is selected, an error will be returned when the input exceeds the maximum input token length. | The input data type is categorical. The default value is NONE. | No |
