ACE-Step
Apache-2.0 text-to-music model: full songs, commercial use OK
Editorially reviewedChecked Oct 2026How we review
Free plan Self-hosted
Toolglade’s take
ACE-Step is the most commercially usable generative model on the viral list: Apache-2.0 (commercial use OK), it makes full songs — vocals and lyrics — and renders a short track in seconds on a consumer GPU. It is a standalone music model, not a Claude/MCP tool. The repo is v1; a v1.5 is announced but lives on a separate page. Verified on 2026-10-14.
Should you use ACE-Step?

- Biggest strength
- Apache-2.0 — commercial use allowed
- Biggest weakness
- Requires a CUDA GPU
- Pricing

About ACE-Step
ACE-Step is an Apache-2.0 text-to-music foundation model that generates full songs with vocals and lyrics and allows commercial use.
ACE-Step (a collaboration involving ACE Studio and StepFun) is a music foundation model rather than a narrow "soundtrack generator": it produces complete songs with vocals and lyrics in 19 languages, and supports editing, remixing, and LoRA fine-tuning. On an RTX 3090 it can render roughly a minute of audio in a few seconds, so short game tracks are quick. The standout feature for a studio is the license: Apache-2.0, which permits commercial use — the most permissive on the viral list. It needs a GPU (about 8GB VRAM with offload) and is unrelated to Claude or MCP; it is included here because the thread listed it, with its real scope and license made clear. Note the repo is ACE-Step v1; a v1.5 is announced separately.
