| # CARA-native Stable Audio Open Small |
|
|
| This is the Phase 2 CARA-native Stable Audio Open Small checkpoint used in the |
| CARA cross-architecture attribution research. The fork exposes batch-aligned |
| native DiT features and trains a checkpoint-owned hierarchical 98-pool/9-family |
| head together with the diffusion model. |
|
|
| The release is an open-weight peer-review artifact, not an OSI open-source |
| model. Its use and redistribution remain subject to the Stability AI Community |
| License. |
|
|
| ## Contents |
|
|
| - `phase2/native_stable_audio_full.ckpt`: completed 7,665-step model/head |
| checkpoint. |
| - `phase2/native_stable_audio_training_report.json`: training contract. |
| - `registry/`: exact CARA pool/family ordering used by the head. |
| - `evidence/`: authoritative prompt-visible and fixed-audio score reports. |
| - `source/`: exact source snapshot used to load and evaluate the checkpoint. |
| - `LICENSE` and `NOTICE`: required upstream license and attribution. |
| - `cara_model_manifest.json`: byte sizes and SHA-256 values for release files. |
|

| ## Reload |
|
|
| ```bash |
| hf download sammoran-phd/cara-native-stable-audio \ |
| --revision phase2-v1 \ |
| --local-dir cara-native-stable-audio-release |
| |
| mkdir cara-native-stable-audio-source |
| tar -xzf \ |
| cara-native-stable-audio-release/source/cara-native-stable-audio-source.tar.gz \ |
| -C cara-native-stable-audio-source |
| cd cara-native-stable-audio-source |
| ``` |
|
|
| Load `stabilityai/stable-audio-open-small` with `stable-audio-tools`, attach the |
| included fork's `CARAAttributionHead`, and load |
| `phase2/native_stable_audio_full.ckpt`. The included benchmark scripts perform |
| the registry-hash, global-step, native-head, and feature-shape checks before |
| evaluation. The complete invocation is in the `cara-native-musicmodels` Phase 2 |
| job specification. |
|
|
| ## Evaluation boundary |
|
|
| On the primary 780-waveform balanced fixed-audio core, this checkpoint scored |
| 7.82% exact top-1, 25.64% top-3, 33.21% pool-derived family accuracy, 6.90% ECE, |
| and 100% registry-valid output. On the earlier 320-row prompt-visible benchmark |
| it scored 23.75% exact top-1, 56.56% top-3, and 99.38% family accuracy. |
|
|
| The fixed-audio result is the primary estimate of audio-conditioned attribution. |
| The much higher prompt-visible family score is dominated by visible semantic |
| taxonomy and is not evidence of reliable exact source identification. |
|
|
| ## Intended use and limitations |
|
|
| This release is intended for academic reproduction, interface auditing, and |
| controlled attribution experiments. It is not a provenance, copyright |
| identification, royalty allocation, or safety system. The primary fixed-audio |
| core covers 39 of 98 pools and represents one source corpus and one training |
| run. |
