Model overview
**Chatterbox** is a family of three state-of-the-art, open-source text-to-speech models by Resemble AI. We are excited to introduce **Chatterbox-Turbo**, our most efficient model yet. Built on a streamlined 350M parameter architecture, **Turbo** delivers high-quality speech with less compute and VRAM than our previous models. We have also distilled the speech-token-to-mel decoder, previously a bottleneck, reducing generation from 10 steps to just **one**, while retaining high-fidelity audio output. **Paralinguistic tags** are now native to the Turbo model, allowing you to use `[cough]`, `[laugh]`, `[chuckle]`, and more to add distinct realism. While Turbo was built primarily for low-latency voice agents, it excels at narration and creative workflows.

Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.
Source prices & cost analysis
Prices vary by channel, region and configuration. Channel quotes are listed independently and are not treated as a single official provider price.

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.
