g2p-multilingual-byT5-tiny-mlx
MLX-compatible weights for charsiu/g2p_multilingual_byT5_tiny_16_layers_100 โ a ByT5-based multilingual grapheme-to-phoneme converter supporting 100 languages.
Converted from PyTorch to SafeTensors format for use with mlx-swift and MLX.

Usage with CharsiuG2PKit (Swift)
import CharsiuG2PKit
let g2p = try G2P(modelDirectory: modelURL)
let ipa = g2p.convert("hello", language: "eng-us")
// "หhษษซoส"
See CharsiuG2PKit for full documentation.
Usage with Python MLX
import mlx.core as mx
from mlx.utils import tree_unflatten
from safetensors import safe_open
tensors = {}
with safe_open("model.safetensors", framework="numpy") as f:
for key in f.keys():
tensors[key] = mx.array(f.get_tensor(key))
Conversion
Converted from pytorch_model.bin using:
uv run scripts/convert_weights.py --model charsiu/g2p_multilingual_byT5_tiny_16_layers_100
Shared tensor aliases (encoder.embed_tokens.weight, decoder.embed_tokens.weight) are deduplicated โ only shared.weight is kept.
