| description.long | FastEmbed is a Python library that generates text and image embeddings using ONNX Runtime, eliminating the need for large PyTorch dependencies. It supports various embedding models including sparse embeddings, late-interaction models, and cross-encoders, making it suitable for serverless and resource-constrained environments. | A managed platform that processes and indexes documents, images, audio, and video content, providing semantic search with optional reranking through an API. Pricing is usage-based with optional monthly credit allowances. |
