Kokoro-82M (self-hosted)

Open-weight (Apache-2.0) 82M-parameter TTS model with 54 voices in 8 languages, small enough to run on CPU or a modest GPU.

With only 82M parameters, the model runs on CPU or on a single consumer GPU with about 1-2 GB of VRAM, so a small instance can serve hundreds of millions of characters a month. The model card puts serving costs under $1 per million characters, and DeepInfra's hosted $0.62 is a useful benchmark for whether self-hosting is worth the effort. Its 54 voices in 8 languages suit narration, but there is no voice cloning; unlike Voxtral TTS's non-commercial weights, the licence is Apache-2.0.

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. The model card cites serving costs of "under $1 per million characters of text input" or "under $0.06 per hour of audio output"; DeepInfra's hosted price of $0.62 per million characters is a good market reference. At 82M parameters it runs on CPU (a browser WASM build reports roughly real-time speed on one laptop thread) and on a single consumer GPU with ~1-2 GB of VRAM, so a small GPU instance can serve hundreds of millions of characters a month. v1.0 (January 2025) has 54 voices in 8 languages; quality is good for narration but below the expressive premium models, and there is no voice cloning. Developed by the independent hexgrad project; data stays wherever you run it.

Managed alternatives

At 10M characters / month. Adjust usage and requirements.

Kokoro-82M 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 Kokoro-82M 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.
