The performance in q8-hi dips below the old base, even if generally int quants underperform in this model.

The mxfp8 shows the most degradation.

Model abliteration in the previous version shows a dramatic increase in performance above base.

More metrics coming soon.

from mlx_lm import load, generate

model, tokenizer = load("granite-4.2-8b-mxfp8-mlx")

prompt = "hello"

if tokenizer.chat_template is not None:
    messages = [{"role": "user", "content": prompt}]
    prompt = tokenizer.apply_chat_template(
        messages, add_generation_prompt=True, return_dict=False,
    )
