The engine, and the models
it is made of

One runtime underneath all of it. The engine is what the platform runs on; the models are the layers it owns, arriving on their own as they are ready.

Alebex Voice Engine

A real-time voice engine where everything streams end to end: streaming speech-to-text, turn control, the hallucination gate, barge-in classification, multimodal intent understanding and streaming synthesis.
