Text Embeddings Inference

Text Embeddings Inference (TEI) is a comprehensive toolkit designed for efficient deployment and serving of open source text embeddings models. It enables high-performance extraction for the most popular models, including FlagEmbedding, Ember, GTE, and E5.

TEI offers multiple features tailored to optimize the deployment process and enhance overall performance.

Key Features:

• Streamlined Deployment: TEI eliminates the need for a model graph compilation step for an easier deployment process.
• Efficient Resource Utilization: Benefit from small Docker images and rapid boot times, allowing for true serverless capabilities.
• Dynamic Batching: TEI incorporates token-based dynamic batching thus optimizing resource utilization during inference.
• Optimized Inference: TEI leverages Flash Attention, Candle, and cuBLASLt by using optimized transformers code for inference.
• Safetensors weight loading: TEI loads Safetensors weights for faster boot times.
• Production-Ready: TEI supports distributed tracing through Open Telemetry and exports Prometheus metrics.
