MyShell.ai / MIT · Text → speech · 50M params · MIT (commercial OK)

A fast, lightweight multilingual TTS library that runs in real time on CPU, popular for low-latency, multi-accent speech.

What it costs to run — $0 markup

On your own machine — $0. Runs free if you have about 1.0 GB of VRAM (CPU-real-time capable; minimal VRAM), via MeloTTS.
Rent a GPU — from $0.26/hr. Fits RTX 3090 24GB at the direct vendor price ($0 markup) — pay only for the minutes you generate.
Download the weights — free. Open weights at myshell-ai/MeloTTS-English.

Note: generative-media models are billed per image / per second / per minute on hosted services — not per token. Running locally or on your own rented GPU is usually far cheaper and keeps your data on your machine.
