EmbedAnything is a minimalist, yet highly performant, lightning-fast, lightweight, multisource, multimodal, and local embedding pipeline built in Rust. Whether you're working with text, images, audio, PDFs, websites, or other media, EmbedAnything streamlines the process of generating embeddings from various sources and seamlessly streaming (memory-efficient-indexing) them to a vector database. It supports dense, sparse, ONNX, model2vec and late-interaction embeddings, offering flexibility for a wide range of use cases.

💡What is Vector Streaming

Vector Streaming enables you to process and generate embeddings for files and stream them, so if you have 10 GB of file, it can continuously generate embeddings Chunk by Chunk, that you can segment semantically, and store them in the vector database of your choice, Thus it eliminates bulk embeddings storage on RAM at once.

The embedding process happens separetly from the main process, so as to maintain high performance enabled by rust MPSC, and no memory leak as embeddings are directly saved to vector database. Find our blog.

⭐ Supported Models

We support any hugging-face models on Candle. And We also support ONNX runtime for BERT and ColPali.

How to add custom model on candle: from_pretrained_hf

model = EmbeddingModel.from_pretrained_hf(
    WhichModel.Bert, model_id="model link from huggingface"
)
config = TextEmbedConfig(chunk_size=1000, batch_size=32)
data = embed_anything.embed_file("file_address", embedder=model, config=config)

config = TextEmbedConfig(
    chunk_size=1000,
    batch_size=8,
    splitting_strategy="sentence",
    late_chunking=True,
)

# Embed a single file
data: list[EmbedData] = model.embed_file("test_files/attention.pdf", config=config)

🧑‍🚀 Getting Started

💚 Installation

pip install embed-anything

For GPUs and using special models like ColPali

pip install embed-anything-gpu

Usage

➡️ Usage For 0.3 and later version

To use local embedding: we support Bert and Jina

model = EmbeddingModel.from_pretrained_local(
    WhichModel.Bert, model_id="Hugging_face_link"
)
data = embed_anything.embed_file("test_files/test.pdf", embedder=model)

For multimodal embedding: we support CLIP

Requirements Directory with pictures you want to search for example we have test_files with images of cat, dogs etc

import embed_anything
from embed_anything import EmbedData
model = embed_anything.EmbeddingModel.from_pretrained_local(
    embed_anything.WhichModel.Clip,
    model_id="openai/clip-vit-base-patch16",
    # revision="refs/pr/15",
)
data: list[EmbedData] = embed_anything.embed_image_directory("test_files", embedder=model)
embeddings = np.array([data.embedding for data in data])
query = ["Photo of a monkey?"]
query_embedding = np.array(
    embed_anything.embed_query(query, embedder=model)[0].embedding
)
similarities = np.dot(embeddings, query_embedding)
max_index = np.argmax(similarities)
Image.open(data[max_index].text).show()

Audio Embedding using Whisper

requirements: Audio .wav files.

import embed_anything
from embed_anything import (
    AudioDecoderModel,
    EmbeddingModel,
    embed_audio_file,
    TextEmbedConfig,
)
# choose any whisper or distilwhisper model from https://huggingface.co/distil-whisper or https://huggingface.co/collections/openai/whisper-release-6501bba2cf999715fd953013
audio_decoder = AudioDecoderModel.from_pretrained_hf(
    "openai/whisper-tiny.en", revision="main", model_type="tiny-en", quantized=False
)
embedder = EmbeddingModel.from_pretrained_hf(
    embed_anything.WhichModel.Bert,
    model_id="sentence-transformers/all-MiniLM-L6-v2",
    revision="main",
)
config = TextEmbedConfig(chunk_size=1000, batch_size=32)
data = embed_anything.embed_audio_file(
    "test_files/audio/samples_hp0.wav",
    audio_decoder=audio_decoder,
    embedder=embedder,
    text_embed_config=config,
)
print(data[0].metadata)

Using ONNX Models

To use ONNX models, you can either use the ONNXModel enum or the model_id from the Hugging Face model.

model = EmbeddingModel.from_pretrained_onnx(
  WhichModel.Bert, model_name = ONNXModel.AllMiniLML6V2Q
)

For some models, you can also specify the dtype to use for the model.

model = EmbeddingModel.from_pretrained_onnx(
    WhichModel.Bert, ONNXModel.ModernBERTBase, dtype = Dtype.Q4F16
)

Using the above method is best to ensure that the model works correctly as these models are tested. But if you want to use other models, like finetuned models, you can use the hf_model_id and path_in_repo to load the model like below.

model = EmbeddingModel.from_pretrained_onnx(
  WhichModel.Jina, hf_model_id = "jinaai/jina-embeddings-v2-small-en", path_in_repo="model.onnx"
)

To see all the ONNX models supported with model_name, see here

⁉️FAQ

Do I need to know rust to use or contribute to embedanything?

The answer is No. EmbedAnything provides you pyo3 bindings, so you can run any function in python without any issues. To contibute you should check out our guidelines and python folder example of adapters.

How is it different from fastembed?

We provide both backends, candle and onnx. On top of it we also give an end-to-end pipeline, that is you can ingest different data-types and index to any vector database, and inference any model. Fastembed is just an onnx-wrapper.

We've received quite a few questions about why we're using Candle.

One of the main reasons is that Candle doesn't require any specific ONNX format models, which means it can work seamlessly with any Hugging Face model. This flexibility has been a key factor for us. However, we also recognize that we’ve been compromising a bit on speed in favor of that flexibility.

Roadmap

Quick Start

Guidelines

🏎️ RoadMap

Accomplishments

One of the aims of EmbedAnything is to allow AI engineers to easily use state of the art embedding models on typical files and documents. A lot has already been accomplished here and these are the formats that we support right now and a few more have to be done.

Adding Fine-tuning

One of the major goals of this year is to add finetuning these models on your data. Like a simple sentence transformer does.

🖼️ Modalities and Source

We’re excited to share that we've expanded our platform to support multiple modalities, including:

• Audio files

• Markdowns

• Websites

• Images

• Videos

• Graph

This gives you the flexibility to work with various data types all in one place! 🌐

⚙️ Performance

We now support both candle and Onnx backend
➡️ Support for GGUF models

🫐Embeddings:

We had multimodality from day one for our infrastructure. We have already included it for websites, images and audios but we want to expand it further to.

➡️ Graph embedding -- build deepwalks embeddings depth first and word to vec
➡️ Video Embedding
➡️ Yolo Clip

🌊Expansion to other Vector Adapters

We currently support a wide range of vector databases for streaming embeddings, including:

• Elastic: thanks to amazing and active Elastic team for the contribution
  
• Weaviate

• Qdrant
  
• Milvus
  
• Chroma
  

How to add an adpters: https://starlight-search.com/blog/2024/02/25/adapter-development-guide.md

💥 Create WASM demos to integrate embedanything directly to the browser.

💜 Add support for ingestion from remote sources

➡️ Support for S3 bucket
➡️ Support for azure storage
➡️ Support for google drive/dropbox

But we're not stopping there! We're actively working to expand this list.

Want to Contribute? If you’d like to add support for your favorite vector database, we’d love to have your help! Check out our contribution.md for guidelines, or feel free to reach out directly [e-mail]. Let's build something amazing together! 💡
