The Cohere Embed 4 multimodal embeddings model is now generally available on Amazon SageMaker JumpStart. The Embed 4 model is built for multimodal business documents, has leading multilingual capabilities, and offers notable improvement over Embed 3 across key benchmarks.
In this post, we discuss the benefits and capabilities of this new model. We also walk you through how to deploy and use the Embed 4 model using SageMaker JumpStart.
Cohere Embed 4 overview
Embed 4 is the most recent addition to the Cohere Embed family of enterprise-focused large language models (LLMs). It delivers state-of-the-art multimodality. This is useful because businesses continue to store the majority of important data in an unstructured format. Document formats include intricate PDF reports, presentation slides, as well as text-based documents or design files that might include images, tables, graphs, code, and diagrams. Without the ability to natively understand complex multimodal documents, these types of documents become repositories of unsearchable information. With Embed 4, enterprises and their employees can search across text, image, and multimodal documents. Embed 4 also offers leading multilingual capabilities, understanding over 100 languages, including Arabic, French, Japanese, and Korean. This capability is useful to global enterprises that handle documents in multiple languages. Employees can also find critical data even if the information isn’t stored using a language they speak. Overall, Embed 4 empowers global enterprises to break down language barriers and manage information in the languages most familiar to their customers.
In the following diagram (source), each language category represents a blend of public and proprietary benchmarks (see more details). Tasks ranged from monolingual to cross-lingual (English as the query language and the respective monolingual non-English language as the corpus). Dataset performance metrics are measured by NDCG@10.
Embeddings models are already being used to handle documents with both text and images. However, optimal performance usually requires additional complexity because a multimodal generative model must preprocess documents into a format that is suitable for the embeddings model. Embed 4 can transform different modalities such as images, texts, and interleaved images and texts into a single vector representation. Processing a single payload of images and text decreases the operational burden associated with handling documents.
Embed 4 can also generate embeddings for documents up to 128,000 tokens, approximately 200 pages in length. This extended capacity alleviates the need for custom logic to split lengthy documents, making it straightforward to process financial reports, product manuals, and detailed legal contracts. In contrast, models with shorter context lengths force developers to create complex workflows to split documents while preserving their logical structure. With Embed 4, as long as a document fits within the 128,000-token limit, it can be converted into a high-quality, unified vector representation.
Embed 4 also has enhancements for security-minded industries such as finance, healthcare, and manufacturing. Businesses in these regulated industries need models that have both strong general business knowledge as well as domain-specific understanding. Business data also tends to be imperfect. Documents often come with spelling mistakes and formatting issues such as improper portrait and landscape orientation. Embed 4 was trained to be robust against noisy real-world data that also includes scanned documents and handwriting. This further alleviates the need for complex and expensive data preprocessing pipelines.
Use cases
In this section, we discuss several possible use cases for Embed 4. Embed 4 unlocks a range of capabilities for enterprises seeking to streamline information discovery, enhance generative AI workflows, and optimize storage efficiency. Below, we highlight several keys use cases that demonstrate the versatility of Embed 4 in a range of regulated industries.
Simplifying multimodal search
You can take advantage of Embed 4 multimodal capabilities in use cases that require point semantic search. For example, in the retail industry, it might be helpful to search with both text and image. An example search phrase can even include a modifier (for example, “Same style pants but with no stripes”). The same logic can be applied to an analyst’s workflow where users might need to find the right charts and diagrams to explain trends. This is traditionally a time-consuming process that requires manual effort to sift through documents and contextualize information. Because Embed 4 has enhancements for finance, healthcare, and manufacturing, users in these industries can take advantage of built-in domain-specific understanding as well as strong general knowledge to accelerate the time to value. With Embed 4, it’s straightforward to conduct research and turn data into actionable insights.
Powering Retrieval Augmented Generation workflows
Another use case is Retrieval Augmented Generation (RAG) applications that require access to internal information. With the 128,000 context length of Embed 4, businesses can use existing long-form documents that include images without the need to implement complex preprocessing pipelines. An example might be a generative AI application built to assist analysts with M&A due diligence. Having access to a broader repository of information increases the likelihood of making informed decisions.
Optimizing agentic AI workflows with compressed embeddings
Businesses can use intelligent AI agents to reduce unnecessary costs, automate repetitive tasks, and reduce human errors. AI agents need relevant and contextual information to perform tasks accurately. This is done through RAG. The generative model as part of RAG that powers the conversational experience relies on a search engine that is connected to company data sources to retrieve relevant information before providing the final response. For example, an agent might need to extract relevant conversation logs to analyze customer sentiment about a specific product and deduce the most effective next step in a customer interaction.
Embed 4 is the optimal search engine for enterprise AI assistants and agents, which improves the accuracy of responses and mitigates against hallucinations.
At scale, storing embeddings can lead to high storage costs. Embed 4 is designed to output compressed embeddings, where users can choose their own dimension size (example: 256, 512, 1024, and 1536). This helps organizations to save up to 83% on storage costs while maintaining search accuracy.
The following diagram illustrates retrieval quality vs. storage cost across different models (source). Compression can occur on the format precision of the vectors (binary, int8, and fp32) and the dimension of the vectors. Dataset performance metrics are measured by NDCG@10.
Using domain-specific understanding for regulated industries
With Embed 4 enhancements, you can surface relevant insights from complex financial documents like investor presentations, annual reports, and M&A due diligence files. Embed 4 can also extract key information from healthcare documents such as medical records, procedural charts, and clinical trial reports. For manufacturing use cases, Embed 4 can handle product specifications, repair guides, and supply chain plans. These capabilities unlock a broader range of use cases because enterprises can use models out of the box without costly fine-tuning efforts.
