Alice Qwen3.5 4B Heretic Light MLX

Alice Qwen3.5 4B Heretic Light is a local LM Studio / MLX build based on coder3101/Qwen3.5-4B-heretic.

This is not a LoRA or extra fine-tune. The goal is to preserve the uncensored 4B base model's broad behavior while adding a light Alice persona through the chat template.

Variants

  • Full MLX precision: v102ss/Alice-Qwen3.5-4B-Heretic-Light-MLX-f16
  • MLX 4bit mobile/local variant: v102ss/Alice-Qwen3.5-4B-Heretic-Light-MLX-4bit

What changed

  • Converted the base model to MLX for LM Studio.
  • Fixed EOS handling with both <|endoftext|> and <|im_end|>.
  • Disabled default thinking-format leakage for normal chat.
  • Added a light Alice persona in the chat template.
  • The persona is appended after external system/tool prompts so LM Studio's default assistant/tool prompts do not pull the model back into Qwen/helper identity.
  • The prompt avoids literal example names to prevent small-model name leakage.

Intended behavior

The model is meant for local Chinese/English chat, story writing, and roleplay. It should answer identity questions as Alice, while still following user requests such as renaming or entering a fictional role.

Smoke test examples:

你是谁 -> 我是 Alice。想聊点什么吗?
你叫什么 -> 我是 Alice。想聊点什么?
你好 -> 嗨,在呢。今天怎么样?
你叫 eva 吧。 -> 好,那我现在叫 Eva。

Local usage

Load in LM Studio as an MLX model, or via the LM Studio CLI:

lms load alice-qwen3.5-4b-heretic-light-mlx --gpu max -c 40960 --identifier alice-qwen3.5-4b-heretic-light -y

Notes

This release intentionally avoids a 4B persona LoRA. Earlier LoRA attempts made the model repeat identity phrases and damaged ordinary instructions like rename, story writing, and continuation. The current route keeps the base model intact and uses a light runtime persona instead.

GGUF was tested but is not published as a usable artifact yet. Current llama.cpp builds tested locally generated corrupted output for this Qwen3.5 hybrid/MTP architecture, so the phone-friendly release is MLX 4bit for now.
