Model overview
> **Compatibility:** Current model artifacts require `sopro>=2.2.0` or `@soprotts/onnx-web>=0.3.0`; upgrade with `pip install -U sopro` or `npm install @soprotts/onnx-web@latest`. Sopro (from the Portuguese word for "breath/blow") is a lightweight voice-cloning text-to-speech model family. This repo ships **sopro-v2-turbo**, a 120M-parameter open model that streams, runs comfortably on a laptop CPU or in the browser, and reaches SOTA-level intelligibility against much larger systems. The full story, evaluations, and audio samples are in the blog post. - **120M parameters** - **English, European Portuguese, French, and German** - **Streaming** with ~300 ms time-to-first-audio on a laptop CPU - **Zero-shot voice cloning** from 5-20 seconds of reference audio - **0.24 RTF offline / 0.21 RTF streaming** on an M3 CPU, 0.07 RTF on an H100 - **Runs in the browser** via an ONNX runtime

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
