Run voice cloning & TTS on a cloud GPU, in 30 seconds
Text-to-speech and voice cloning with a web interface and API. Voicebox bundles modern open TTS and voice-cloning models behind a web interface and an API: clone a voice from a short sample, synthesise long-form narration, export WAV. Rent a small card for interactive use or batch narrations overnight. From $0.020/hr on an interruptible RTX 3060.
Template is free
You pay the GPU price only: Voicebox TTS on a RTX 3060 is $0.041/hr on-demand, $0.020/hr interruptible, billed per second.
Volumes for state
Models, datasets and outputs live on a $0.08/GB/mo volume; the instance stays disposable.
Private by default
Dedicated GPU, encrypted disk, crypto payments, no KYC, no stored IPs — Jupyter and SSH behind your own credentials.
Best GPUs for Voicebox TTS
Three price points that run this template well — Good, Better, Best. Every model in the catalogue works; these are the value picks.
| Tier | GPU | VRAM | On-demand | Interruptible | Why this card | Action |
|---|---|---|---|---|---|---|
| Good | RTX 3060 | 12 GB | $0.041 | $0.020 | 12 GB is plenty for most TTS models. | Deploy |
| Better | RTX 4070 | 12 GB | $0.066 | $0.033 | Faster synthesis for batch narration. | Deploy |
| Best | RTX 4090 | 24 GB | $0.262 | $0.131 | 24 GB for larger voice models and parallel requests. | Deploy |

Deploy Voicebox TTS from the console, CLI or API
Pick the template in the console deploy bar, or script it:
- Console — filter by GPU, choose Voicebox TTS in the template picker, set disk and env, deploy.
- CLI — pip install powergpu, then the command on the right. CLI reference.
- API — POST /v1/instances with "template": "voicebox-tts". REST reference.
- Own image — any OCI reference works too; we inject the NVIDIA runtime. Template docs.

Voicebox TTS on a cloud GPU: FAQ
Environment variables, ports and custom images are covered in the template docs.
How much does it cost to run Voicebox TTS on a cloud GPU?
Only the GPU price — the template is free. From $0.020/hr on an interruptible RTX 3060, $0.041/hr on-demand on a RTX 3060. Billing is per second, so an hour of tinkering costs an hour, not a day. Storage is $0.08/GB/month.
How long does Voicebox TTS take to start?
About 30 seconds from the deploy click: the image is pre-cached on hosts, ports are mapped and TLS is terminated for you. Restarting a stopped instance is faster, and your disk is exactly as you left it.
Can I keep my models and outputs between sessions?
Yes — attach a volume at deploy. Everything on the volume survives instance destruction and mounts on the next instance in the region in seconds, at $0.08/GB/month. The instance disk itself survives stop/start but not destroy.
Can I use it as an API?
Yes — the REST endpoint accepts text plus a reference sample and returns audio; it is reachable on the mapped port with TLS.
