About Towhee
Towhee is an open-source Python framework for building neural data processing and embedding pipelines that transform unstructured data — images, video, audio, text, and molecular data — into vector embeddings. It provides 700+ pre-trained models across computer vision, NLP, multimodal, audio, and medical domains, along with ready-to-use pipelines for tasks like RAG, image search, and video deduplication. Created by Zilliz, the company behind the Milvus vector database, Towhee serves as a lightweight ETL layer for AI applications.
