LFM2.5-1.2B-JP-202606-MLX-4bit

This is an MLX conversion of LiquidAI/LFM2.5-1.2B-JP-202606 (~0.64 GB).

Precision

Quantized to 4-bit (group size 64). Two precision-sensitive tensors are protected, mirroring llama.cpp's policy:

• Tied embeddings (= output head) are kept at 6-bit. LiquidAI/LFM2.5-1.2B-JP-202606 ties embed_tokens with the LM head, so a uniform low-bit quant would degrade both the input lookup and the output logits.
• The MoE router gate is kept in fp32 — not applicable here, since this is a dense model with no experts.

Use with mlx-lm

pip install mlx-lm

from mlx_lm import load, generate

model, tokenizer = load("LiquidAI/LFM2.5-1.2B-JP-202606-MLX-4bit")
messages = [{"role": "user", "content": "日本の首都はどこですか？"}]
prompt = tokenizer.apply_chat_template(messages, add_generation_prompt=True)
print(generate(model, tokenizer, prompt, max_tokens=128, verbose=True))
