How to run Stable Audio Open 1.0 locally

Stability AI · Text → audio · 1.05B params · Stability AI Community License (commercial OK)

A latent-diffusion model for text-to-audio that creates sound effects, samples and short stereo music passages, trained only on CC-licensed audio; commercial-free under the $1M threshold.

What it costs to run — $0 markup

On your own machine — $0. Runs free if you have about 8.0 GB of VRAM (~6-8GB; generates up to 47s stereo at 44.1kHz), via ComfyUI / Diffusers.
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 stabilityai/stable-audio-open-1.0.

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.
