mlx-community/gpt-oss-120b-mxfp4-bf16#

This model mlx-community/gpt-oss-120b-mxfp4-bf16 was converted to MLX format from openai/gpt-oss-120b using mlx-lm version 0.31.3.

Use with mlx#

pip install mlx-lm
from mlx_lm import load, generate

model, tokenizer = load("mlx-community/gpt-oss-120b-mxfp4-bf16")

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,
    )

response = generate(model, tokenizer, prompt=prompt, verbose=True)
