Chatterbox (self-hosted)
Resemble AI's open-source (MIT) Chatterbox TTS models with zero-shot voice cloning, run on your own GPUs. Resemble no longer sells paid TTS.
Chatterbox's Turbo and Multilingual models provide zero-shot voice cloning under the MIT license. Run them on your own GPUs without per-character fees, allowing for hosting, maintenance and voice consent. If you prefer a hosted API, DeepInfra serves both models at $1.00 per million characters. Check its data-handling terms separately.

Pricing
Operating cost not estimated · servers, licenses and engineering time are yours. See notes for software editions and license terms.
Self-hosted: budget for hardware, storage and maintenance. Resemble AI (San Francisco) has pivoted to deepfake detection: its pricing page lists only detection products and states that Chatterbox and its generative voice models "remain open and free to build on" but "are no longer offered as commercial paid products". Variants include Chatterbox Turbo and Chatterbox Multilingual. If you would rather not run GPUs, DeepInfra hosts chatterbox-turbo and chatterbox-multilingual at $1.00 per million characters (deepinfra.com/models/text-to-speech). Data stays wherever you run it.
Managed alternatives
At 10M characters / month. Adjust usage and requirements.
Chatterbox has no bill to estimate: you pay for the servers, storage and time to run it. The cheapest managed option here is Kokoro-82M on DeepInfra at $74/yr, so running Chatterbox yourself saves money only if hosting and upkeep stay below about $6.20 a month.

The price difference leaves out migration costs, operating costs and any features you’d need to replace.
