# ACE-Step 1.5 Turbo — WebGPU model packages

Content-addressed model packages for the browser WebGPU port of
[ACE-Step 1.5 Turbo](https://huggingface.co/ACE-Step/Ace-Step1.5), consumed by
[FluidInference/fluidaudio-web](https://github.com/FluidInference/fluidaudio-web)'s
`/music` page (runtime vendored at `packages/acestep`).

This is a byte-exact, SHA-256-verified mirror of the production tuple built by
the runtime's deterministic converter (`model/convert.py --profile production`)
and originally published by the port's author, **Hamza Qayyum** (Narcotic
Software) — see the original demo at https://acestep.narcotic.sh.

## Contents (113 payloads + 3 manifests, 5,747,730,175 bytes)

| Package | Prefix | Files | Bytes |
| --- | --- | --- | --- |
| Direct reference (encoders, packed-BF16) | `v1/reference/18f36c64…` | 58 | 2,558,130,431 |
| DiT revision 7 (FP16 dense) | `v1/dit-revision7/d3fc0020…` | 48 | 3,020,808,192 |
| VAE revision 7 (FP16) | `v1/vae-revision7/36a54d79…` | 7 | 168,791,552 |

Every payload prefix and manifest filename is content-addressed and immutable;
manifests carry per-file SHA-256s that the runtime authenticates before use.
The direct manifest excludes the optional planner/semantic material.

## Licenses

The browser port and packaging are MIT (see `LICENSE-ace-step-1.5.wgsl`).
Model weights retain their upstream ACE-Step and Qwen terms — see
`THIRD_PARTY_LICENSES` and the pinned source identities inside each manifest.
