Nomic AI Releases Embeddings, A truly Open Source Embedding Model

Nomic embeded-text-v1 is the newest SOTA long-context embedding model. Tired of drowning in unstructured data – text documents, images, audio, you name it – that your current tools just can’t handle? Welcome to the open seas of understanding, where Nomic AI’s Embeddings act as your life raft, transforming this chaos into a treasure trove of insights.

Forget rigid spreadsheets and clunky interfaces. Nomic Atlas, the platform redefining how we interact with information, empowers you to explore, analyze, and structure massive datasets with unprecedented ease. But what truly sets Nomic apart is its commitment to openness and accessibility. That’s where Embeddings, their latest offering, comes in.

Embeddings are the secret sauce, the vector representations that unlock the meaning within your data. Imagine each data point as a ship on a vast, trackless ocean. Embeddings act as lighthouses, guiding you towards similar data, revealing hidden connections, and making sense of the seemingly incoherent.

And the best part? Nomic’s Embeddings are truly open source, meaning they’re free to use, modify, and share. This transparency fosters collaboration and innovation, putting the power of AI-powered analysis directly in your hands.

The Struggle with Unstructured Data

AI loves structured data. Imagine feeding spaghetti to a baby – that’s like throwing unstructured data at AI. Text documents, images, videos – a tangled mess AI struggles to digest. It craves the neat rows and columns of structured data, the spreadsheets and databases where information sits organized and labeled. Nomic open source AI’s Embeddings are transforming that spaghetti into bite-sized insights, ready for AI and unlock the hidden potential within your data.

Understanding Embeddings

Where Embedding Can Help

Embedding models have the potential to assist companies and developers in several key ways:

  • Handling Long-Form Content: Many organizations have vast troves of long-form content in research papers, reports, articles, and other documents. Embedding models can help make this content more findable and usable. By embedding these documents, the models can enable more semantic search and retrieval, allowing users to find relevant content even if the exact search keywords don’t appear in a document.
  • Auditing Model Behavior: As AI and machine learning models permeate more sensitive and critical applications, explainability and auditability become crucial. Embedding models can assist by providing a meaningful vector space that developers can analyze to better understand model behavior. By examining how certain inputs map to vector spaces, developers can gain insight into how models handle different data points.
  • Enhancing NLP Capabilities: Embedding models serve as a foundational layer that enhances many other natural language processing capabilities. By structuring language in vector spaces, embedding enables better performance downstream on tasks like sentiment analysis, topic modeling, text generation, and more. Embedding essentially extracts more understanding from text.

Embedding models empower more semantic search and retrieval, auditable model behaviors, and impactful NLP capabilities. Companies need embedders to help structure and exploit long-form content. And developers need embedding to infuse AI transparency and interpretability into sensitive applications. The vector spaces embedding provides for language are critical for many modern NLP breakthroughs.

Nomic AI’s Training Details

Nomic AI’s Embeddings boast impressive performance, and understanding their training process sheds light on this achievement. Instead of relying on a single training stage, Nomic employs a multi-stage pipeline, meticulously crafted to extract the most meaning from various sources.

Imagine baking a delicious cake. Each ingredient plays a specific role, and their careful combination creates the final masterpiece. Similarly, Nomic’s pipeline uses different “ingredients” in each stage:

Stage 1: Unsupervised Contrastive Learning:

  • Think of this as building the cake’s foundation. Nomic starts with a large, pre-trained BERT model. Think of BERT as a skilled baker with a repertoire of techniques.
  • Next, they feed BERT a unique dataset of weakly related text pairs. This might include question-answer pairs from forums like StackExchange, reviews with titles and bodies, or news articles with summaries. These pairings help BERT grasp semantic relationships between different types of text.
  • Think of this stage as BERT learning the basic grammar and flavor profiles of different ingredients.

Stage 2: Finetuning with High-Quality Labeled Data:

  • Now, the cake gets its delicious details! Here, Nomic introduces high-quality labeled datasets, like search queries and corresponding answers. These act like precise instructions for the baker, ensuring the cake isn’t just structurally sound but also flavorful.
  • A crucial step in this stage is data curation and hard-example mining. This involves selecting the most informative data points and identifying challenging examples that push BERT’s learning further. Think of this as the baker carefully choosing the freshest ingredients and mastering complex techniques.

This two-stage approach allows Nomic’s Embeddings to benefit from both the broad knowledge base of the pre-trained BERT model and the targeted guidance of high-quality labeled data. The result? Embeddings that capture rich semantic meaning and excel at various tasks, empowering you to unlock the true potential of your unstructured data.


Nomic AI’s Embeddings offer a compelling proposition: powerful performance, unparalleled transparency, and seamless integration. By reportedly surpassing OpenAI’s text-embedding-3-small model and sharing their entire training recipe openly, Nomic empowers anyone to build and understand state-of-the-art embeddings. This democratization of knowledge fosters collaboration and innovation, pushing the boundaries of what’s possible with unstructured data.

There is also seamless integration with popular LLM frameworks like Langchain and Llamaindex makes Nomic Embeddings instantly accessible to developers working on advanced search and summarization tasks. This translates to more efficient data exploration, uncovering hidden connections, and ultimately, deriving deeper insights from your information ocean.

So, whether you’re a seasoned data scientist or just starting your AI journey, Nomic Embeddings are an invitation to dive deeper. With their open-source nature, powerful performance, and seamless integration, they unlock a world of possibilities, empowering you to transform your unstructured data into a gold mine of insights.
