Bottom Line Up Front (BLUF): ACE-Step 1.5 WebGPU is a free NeuralSpace music generator that runs entirely in your browser. Describe a track in words and the ACE-Step 1.5 XL Turbo model builds it on your device: nothing is uploaded, there is no paid API and no tokens are spent.
The model runs locally: on the first visit the browser downloads the weights once and reuses them from cache afterwards. Your prompt and the result never leave the computer — nothing is sent to our server, which is why generation costs no tokens.
Desktop Chrome or Edge with WebGPU support. If the browser cannot run the model locally, the page says so honestly and suggests opening it on a computer.
