Models registry v1.0.1 serves nine languages in three tiers

FastText-ONNX embedding models for nine languages ship in full, fluency, and mini tiers.

  1. One registry, addressed as kotoshu://models/{lang}/{tier}, resolves every model with SHA-256 checksums, license, and minimum engine version; clients try the primary URL, then the mirror, then the vocab.
  2. Per-tier evaluation reports are published for each language. fluency is int8 with the top 50,000 words and near-lossless, while mini is the wasm and edge tier at about 3 MB.
  3. The full tier at about 120 MB also serves from a media-host mirror, so the first setup does not lean on release bandwidth.
