Index-Translate-2B-MLX-4bit

MLX affine 4-bit quantization (group size 64) of IndexTeam/Index-Translate-2B. Weights only re-encoded — no retraining, no fine-tuning.

Text translation only: the upstream checkpoint's vision tower and MTP head are not included. Runs with mlx-lm on Apple Silicon; not a llama.cpp / GGUF model.

Usage

from mlx_lm import load, generate

model, tokenizer = load("zerodegress/Index-Translate-2B-MLX-4bit")
prompt = "请将以下中文文本翻译为英语，直接输出翻译结果，不要进行任何解释。\n\n你好，世界！"
print(generate(model, tokenizer, prompt=prompt, max_tokens=1024))

Prompt template: 请将以下{源语言}文本翻译为{目标语言}，直接输出翻译结果，不要进行任何解释。 (the source-language slot is left empty for auto-detection). Greedy decoding, thinking disabled.
