Impossible Embedding

Impossible Embedding is a local-first server for dense text embeddings with open models. It owns the operational pieces that are easy to get wrong: verified model installation, bounded dynamic batching, predictable cancellation, readiness, metrics, authentication, and graceful shutdown.

Inference runs locally through ONNX Runtime. Nothing calls OpenAI or any other hosted inference service. is only a wire-compatible adapter so existing OpenAI-compatible clients can use a local base URL.
