Libraries

How to use TheCluster/Qwen3.5-27B-Writer-V2-Uncensored-Heretic-MLX-mixed-9.4bit with MLX:

# Make sure mlx-vlm is installed
# pip install --upgrade mlx-vlm

from mlx_vlm import load, generate
from mlx_vlm.prompt_utils import apply_chat_template
from mlx_vlm.utils import load_config

# Load the model
model, processor = load("TheCluster/Qwen3.5-27B-Writer-V2-Uncensored-Heretic-MLX-mixed-9.4bit")
config = load_config("TheCluster/Qwen3.5-27B-Writer-V2-Uncensored-Heretic-MLX-mixed-9.4bit")

# Prepare input
image = ["http://images.cocodataset.org/val2017/000000039769.jpg"]
prompt = "Describe this image."

# Apply chat template
formatted_prompt = apply_chat_template(
    processor, config, prompt, num_images=1
)

# Generate output

How to use TheCluster/Qwen3.5-27B-Writer-V2-Uncensored-Heretic-MLX-mixed-9.4bit with Pi:

Start the MLX server

# Install MLX LM:
uv tool install mlx-lm
# Start a local OpenAI-compatible server:
mlx_lm.server --model "TheCluster/Qwen3.5-27B-Writer-V2-Uncensored-Heretic-MLX-mixed-9.4bit"

Configure the model in Pi

# Install Pi:
npm install -g @mariozechner/pi-coding-agent
# Add to ~/.pi/agent/models.json:
{
  "providers": {
    "mlx-lm": {
      "baseUrl": "http://localhost:8080/v1",
      "api": "openai-completions",
      "apiKey": "none",
      "models": [
        {
          "id": "TheCluster/Qwen3.5-27B-Writer-V2-Uncensored-Heretic-MLX-mixed-9.4bit"
        }
      ]
    }
  }
}

Hermes Agent new

How to use TheCluster/Qwen3.5-27B-Writer-V2-Uncensored-Heretic-MLX-mixed-9.4bit with Hermes Agent:

Start the MLX server

# Install MLX LM:
uv tool install mlx-lm
# Start a local OpenAI-compatible server:
mlx_lm.server --model "TheCluster/Qwen3.5-27B-Writer-V2-Uncensored-Heretic-MLX-mixed-9.4bit"

Configure Hermes

# Install Hermes:
curl -fsSL https://hermes-agent.nousresearch.com/install.sh | bash
hermes setup
# Point Hermes at the local server:
hermes config set model.provider custom
hermes config set model.base_url http://127.0.0.1:8080/v1
hermes config set model.default TheCluster/Qwen3.5-27B-Writer-V2-Uncensored-Heretic-MLX-mixed-9.4bit

Qwen3.5-27B Writer V2 Uncensored Heretic

Quality: quantized (mixed quants per tensor, group size: 32, 9.450 bpw)

Most layers use 8-bit affine quantization with a group size 32; some layers are saved in bf16.

A writing & roleplay finetune of uncensored Qwen3.5 27B. The primary emphasis is on writing quality as it strongly generalizes across both domains.

Recommended Settings:

Chatml template with <think>\n\n</think> or {{char}}: prefill. Only non-thinking was trained, but thinking probably still works.
temperature = 0.7
top_p = 0.95
I do not recommend using high rep pen values like Qwen suggests for the base model. rep_pen = 1.05 or a moderate dry setting should suffice.
