Qwen3.5-9B Uncensored — No-Think Edition (GGUF)

⚡ Zero refusals. Zero thinking delay. 100% local.

This is a patched GGUF of HauhauCS/Qwen3.5-9B-Uncensored-HauhauCS-Aggressive with one key modification: thinking is disabled at the GGUF template level, giving you instant responses without the 15–30 second reasoning delay.

What's different

Qwen3.5 is a thinking model. By default it outputs a <think>...</think> block before every response. This is great for hard problems but brutal for everyday use — you wait 20 seconds for a simple answer.

This model patches the embedded Jinja2 chat template to always output an empty think block:

Original flow:  <think> [400 tokens] </think> → answer    (~25s wait)
This model:     <think></think> → answer                  (<1s wait)

The model's intelligence is encoded in its weights, not the thinking trace. Quality is the same. Speed is 25x better for time-to-first-token.

Want reasoning on demand? Add /think to any message — the model will reason through it fully for that turn only.

3. 3.Done — no config needed, thinking is already patched off

Optimal sampling (Qwen3 official recommended)

Temperature: 0.6
Top-P: 0.95
Top-K: 20
Repeat penalty: 1.0
Max tokens: 4096

llama.cpp

cd lmstudio-uncensored-setup && ./scripts/setup.sh

How the patch works

The Qwen3.5 GGUF contains an embedded Jinja2 chat template with this block:

{%- if enable_thinking is defined and enable_thinking is false %}
    {{- '<think>\n\n</think>\n\n' }}
{%- else %}
    {{- '<think>\n' }}
{%- endif %}

The patch replaces it with just:

{{- '<think>\n\n</think>\n\n' }}

Same file size (padded with spaces), same structure, zero thinking overhead. The patcher script is open source: patch_nothink.py
