It is the dedicated CTC forced-alignment head paired with canary; vocabulary is byte-identical to canary's sentencepiece (16 384 pieces). | | | |---|---| | Architecture | 24-layer Conformer encoder + 1×1 CTC head | | Params | 626 M | | Mel features | 128 | | d_model | 1024 | | CTC vocab | 16 384 + blank | | Subsampling | 8× (dw_striding) | | Self-attention | full rel-pos | | Quantization | bits=8, group_size=64 (MLX default) | | Source | extracted from `canary-1b-v2.nemo` | ## Files | File | Size | |---|---| | `config.json` | preprocessor + encoder + CTC config (with inline vocab) | | `model.safetensors` | q8 weights + bf16 scales/biases | | `tokenizer.model` | canary's sentencepiece (1:1 copy) | ## License CC-BY-4.0 — inherited from `nvidia/canary-1b-v2`.
