Why this model
- Uncensored: built on Luni/Nanbeige-4.3-33B-Heretic, an abliterated Nanbeige 4.3 33B with reduced refusals.
- Mac-native: MLX format for Apple Silicon unified memory, about 17GB on disk.
- Long context: keeps the base model's 262K-token context window.
- Drop-in serving: works with
mlx_lm.generate,mlx_lm.chatand the OpenAI-compatiblemlx_lm.server. - Open license: Apache-2.0, inherited from the base model.
Technical details
| Base model | Luni/Nanbeige-4.3-33B-Heretic, abliterated from Nanbeige/Nanbeige4.3-33B |
| Architecture | LlamaForCausalLM, ~33B parameters, 52 layers, hidden size 7168, 56 heads / 8 KV heads |
| Quantization | MLX affine, 4 bits, group size 64 (~4.5 bits per weight); non-quantized tensors in bfloat16 |
| Size on disk | ~17GB |
| License | Apache-2.0 |
⚠️ Refusal behaviour has been reduced via abliteration, so the model may produce content the original would decline. Use responsibly.
Quickstart
pip install -U mlx-lm
mlx_lm.generate --model junafinity/Nanbeige-4.3-33B-Heretic-Uncensored-MLX-4bit --prompt "Write a fast binary search in Python." --max-tokens 512
from mlx_lm import load, generate
model, tokenizer = load("junafinity/Nanbeige-4.3-33B-Heretic-Uncensored-MLX-4bit")
messages = [{"role": "user", "content": "Write a fast binary search in Python."}]
prompt = tokenizer.apply_chat_template(messages, add_generation_prompt=True)
print(generate(model, tokenizer, prompt=prompt, max_tokens=512, verbose=True))
OpenAI-compatible server:
mlx_lm.server --model junafinity/Nanbeige-4.3-33B-Heretic-Uncensored-MLX-4bit --port 8080
