Qwythos-9B-Claude-Mythos-5-1M MLX (4bit, unlocked)

A conversion of empero-ai/Qwythos-9B-Claude-Mythos-5-1M to Apple's MLX format, quantized to 4bit.

Conversion tool: mlx-maker / mlx-vlm
Source model: empero-ai/Qwythos-9B-Claude-Mythos-5-1M
Base model: Qwen/Qwen3.5-9B
License: Apache-2.0 (inherited from the source model)

About the chat template

Modified variant: the forced identity baked into chat_template.jinja (the Qwythos self-identification) has been removed, and the user's system prompt is now respected. When no system prompt is provided, a neutral default "You are a helpful AI assistant." is used. The weights are unchanged and identical to the same-quantization base variant.

Usage (mlx-vlm)

uv add mlx-vlm

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

model, processor = load("ToPo-ToPo/Qwythos-9B-Claude-Mythos-5-1M-mlx-4bit-unlocked")
messages = [{"role": "user", "content": "Hello"}]
prompt = apply_chat_template(processor, model.config, messages)
print(generate(model, processor, prompt, max_tokens=256))
