Running with mlx-lm

Install mlx-lm:

pip install mlx-lm

Run in Python:

import mlx_lm

model, tokenizer = mlx_lm.load("gabe-rbo/limite-1b-violetto-mlx")

prompt = (
    "<|im_start|>system\n"
    "You are a helpful assistant.\n"
    "Please reason step by step, and put your final answer within \\boxed{}.<|im_end|>\n"
    "<|im_start|>user\n"
    "Solve for x: x^2 - 5x + 6 = 0.<|im_end|>\n"
    "<|im_start|>assistant\n"
)

response = mlx_lm.generate(
    model=model,
    tokenizer=tokenizer,
    prompt=prompt,
    max_tokens=2048,
    temp=0.6,
    top_p=0.95,
)
print(response)

Running as a Local Server (LM Studio / Bionic / OpenAI API compatible)

python -m mlx_lm server --model gabe-rbo/limite-1b-violetto-mlx --port 8080 --temp 0.6 --top-p 0.95

Point LM Studio, Bionic, or any OpenAI-compatible app to http://localhost:8080/v1.
