giux78/buddy-nesso-sft-v1-mlx

Buddy Nesso SFT v1 — MLX

MLX conversion (bfloat16) of giux78/buddy-nesso-sft-v1, a 0.4B parameter bilingual (Italian/English) story and play buddy for children under 8, fine-tuned from mii-llm/nesso-0.4B-agentic.

Converted with mlx-lm for fast local inference on Apple Silicon. See the base model card for training details, the recommended child-safety system prompt, and important safety limitations — this is a research checkpoint, not a production child-safety model.

Usage

pip install mlx-lm

from mlx_lm import load, generate

model, tokenizer = load("giux78/buddy-nesso-sft-v1-mlx")

messages = [
    {"role": "system", "content": "You are Nesso, a warm story and play buddy for children under 8. Keep replies short and safe."},
    {"role": "user", "content": "Ciao! Mi racconti una storia di un piccolo orso?"},
]
prompt = tokenizer.apply_chat_template(messages, add_generation_prompt=True, tokenize=False)
print(generate(model, tokenizer, prompt=prompt, max_tokens=150))

Or from the command line:

mlx_lm.chat --model giux78/buddy-nesso-sft-v1-mlx
