Kokoro-82M text-to-speech (ONNX, 55 voices)

models.skillsafe.ai/[email protected]/

Vetted New WebGPU

Text to speech model for onnxruntime-web (q8). Runs on WebGPU or WASM — 115 MB downloaded once from models.skillsafe.ai, then cached for every SkillSafe app that uses it. Inference happens on your device; nothing you enter is uploaded to load it, and it never costs a credit. Weights from Hugging Face · skillsafe-ai/kokoro-82m, pinned at b4bcae29bf0c — also loadable straight from Hugging Face outside SkillSafe (how).

Each file is served at an immutable URL; the canonical form is the SHA-256 itself. Tokenizer and config JSON are not here by design — they ship in your app bundle.

Signature

Graph inputs and outputs read from the ONNX bytes at vetting — the tensor names your session.run() call feeds and reads. Symbolic dimensions are shown by name.

Inputs

  • input_ids int64 [1, sequence_length]
  • style float32 [1, 256]
  • speed float32 [1]

Outputs

  • waveform float32 [1, num_samples]
Use it in an app declaration · SDK loader · onnxruntime-web · URLs · Hugging Face — generated from this entry

Add to the body of POST /v1/apps/{slug}/releases (or a release session). An unknown or withdrawn model is refused with a 400 naming it; the app page then shows "downloads 115 MB · runs on your device" and /models.txt carries the attribution.

Evaluation

onnx.checker + onnxruntime CPU smoke run with zero-filled inputs at the declared shapes; per-file SHA-256 pinned to the source — imported as published upstream, then checked. Evaluated Sep 22, 2026.

Runs under onnxruntime

Zero-filled inputs at the declared shapes, CPU execution provider on the converter host; the check is that the graph loads, runs, and emits the declared output shapes.

Apps that declare this model get this text in their generated /models.txt, so a licence that requires a notice always carries one.

Every file here was approved by exact SHA-256 after a structural audit of the graph, fetched from a content-pinned source, and is served credential-free at an immutable URL.
