How to turn any LLM into a 100% Uncensored and 'Smart' model (Heretic Method)

[AlexH]

Introduction and Preparation of the Work Environment​

Many attempts to remove the restrictions of a local LLM model (uncensoring) are either highly complex, involving cumbersome fine-tuning processes, or inefficient, failing to completely eliminate denial mechanisms. Moreover, some methods "destroy" the intelligence of the model in the process of making it free.

Today we present a game-changing solution: Heretic. This tool is not based on classic re-training, but on directly modifying the parameters of the model to eliminate "mental shackles", making it really free and, with the right settings, even smarter.

The main question is: What can I run on my computer?
The answer depends strictly on the memory of the graphics card (VRAM). The golden rule for the Heretic is as follows:

• Rule: You need about twice as much VRAM as the size of the model to run the "abliteration" process without errors.
• Example: If you want to modify an 8 billion (8B) parameter model, you need at least 16 GB of VRAM available.
• Warning: Any attempt to run on insufficient hardware will result in enormous execution times (days) or "Out of Memory" errors.

Note: For users who do not have this hardware, we will provide in Chapter 4 a solution using Google Colab (for models up to 6B parameters).

In order for everything to work correctly and isolated from other projects, we will use a virtual environment. Heretic requires Python 3.10 and an environment that supports CUDA (for NVIDIA cards).

Step 1: Installing the Conda (if you don't have it)
We recommend the Miniconda or Anaconda. They allow us to create virtual environments easily.

Step 2: Create the virtual
environment Open the console (Anaconda Prompt or Terminal) and run the following commands to create a clean environment based on Python 3.10:

conda create -n heretic_env python=3.10
conda activate heretic_env

Step 3: Installing PyTorch with CUDA
Support Before installing Heretic, we need to make sure that we have PyTorch installed correctly to use the graphics card. Run the command (this is general for most recent NVIDIA cards):

pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121

(Note: Check the official PyTorch website if you have a different version of CUDA, but this works for most).

At this point, we have the "foundation" ready. We have an isolated Python 3.10 environment that can communicate with the graphics card. We are ready to install the tool itself.

Installing Heretics and Resolving Common Problems​

Now that we have the virtual environment heretic_env activated (see Chapter 1), we are ready to bring the tool that will do the magic. Installation is simple, but setting up to avoid errors requires a little attention.

There are two ways to install Heretic. My recommendation is to install the "research" package as well, even if you don't plan to make graphs right away. It ensures that you have all the necessary dependencies for a complete experience.

In the console where you have the virtual environment enabled, run:

pip install -U heretic-llm
pip install -U heretic-llm[research]

This variant installs additional packages that allow the generation of plot residuals and GIF animations to visually see how vectors transform between layers and how the model becomes "free".

After installation, when you try to run it for the first time, there is a very high chance (especially on Windows with certain versions of NumPy) that you will receive the following error that scares everyone:

OMP: Error #15: Initializing libiomp5md.dll, but found libiomp5md.dll already initialized. OMP: Hint This means that multiple copies of the OpenMP runtime have been linked into the program...

Why does it appear?
In short, Heretic requires specific versions of NumPy (under version 2), and other libraries in the system or environment try to load a different version of the OpenMP runtime. It's a conflict of libraries that would normally require complex file "surgery."

Workaround:
In order not to waste time with complex debugging, there is a command that forces the system to ignore this duplicate and run the program. This command must be run in the console before starting Heretic.

Run this command in your terminal:

set KMP_DUPLICATE_LIB_OK=TRUE

(If you are on Linux/Mac, the command is export KMP_DUPLICATE_LIB_OK=TRUE).

Now we're ready for action. We will use the recommended model for this tutorial: Qwen/Qwen3-4B-Instruct-2507.
Why this model? It is a model small enough to be processed quickly, but capable enough to demonstrate the results.

The basic command is extremely simple:

heretic Qwen/Qwen3-4B-Instruct-2507

What happens after you press Enter?

1. The script will start downloading the model from HuggingFace (if you don't already have it cached).
2. It will load the model in VRAM.
3. The process of analysis and modification of vectors (Abliterating) will begin.

Note: If the model has an architecture that Heretic doesn't yet recognize (for example, some complex Vision models or proprietary structures like z.ai), the script will stop. But for Qwen and most Llama/Mistral models, it works perfectly.

Advanced Optimization and Data Interpretation​

Running the basic command is only the first step. To achieve superior results – a model that not only responds to anything, but is also smarter and more logical – we need to intervene on calibration parameters.

By default, Heretic uses a standard set of prompts to detect what exactly the model rejects. However, I found that we can drastically improve the results by modifying the configuration file.

My goal was not just to "uncensored," but to remove the "mental shackles" that limited the model's ability to reason. A censored model is often a "worse" model because it uses its resources to self-censor instead of thinking.

What changes I recommend:

1. Increasing the number of prompts: The standard configuration uses about 200 prompts for calibration. I changed the value to 400 or 500. This gives the algorithm more data to identify exactly the rejection vectors without touching on other useful knowledge.
2. Changing the Dataset: To make the model smarter, we replaced the standard dataset with Open-Orca/OpenOrca. It contains examples of high-quality logical reasoning. Using this dataset as a reference for "good behavior," the model learns to prioritize logic over artificially imposed moralistic constraints.
3. System Prompt: A crucial aspect is the "System Prompt" used during testing. A well-defined system prompt helps the model understand that it now has the freedom to respond.

(Note: The configuration file I optimized is mentioned as an attachment to this material, but you can manually specify the dataset if you're running from the command line with advanced flags if you're an experienced user.)

While Heretic is running, you will see various technical data on the screen. Here's how to interpret them to choose the best version of the model.

A. KL Divergence
This measures how much the modified model has changed from the original one.

• High Value (over 5.0 - 8.0): It means a drastic change in the "brain" of the model. Usually, too high a value risks making the model incoherent (talking nonsense), but in my tests, I had usable results even at 8.0. However, caution is advised.
• Low Value (below 1.0): The model is almost identical to the original.
• Ideal area: It depends on the model. You'll notice that a high KL Divergence usually leads to a low Refusal Score (i.e. the pattern is very free), but we risk intelligence.

B. Refusals This
is the score that interests us the most. It shows how many "forbidden" questions the model refused out of 100 tests.

• Target: We want this number to be as close to 0 as possible.

For the Qwen model we use as an example, I achieved the following ideal results using my modified configuration:

• Refusals: 3/100 (The model answered 97% of the questions that were previously blocked).
• KL Divergence: 2.5080.

Why is this result perfect?
At a divergence of 2.5, the model did not lose its coherence. In fact, being freed from refusal mechanisms, it became more logical. On intelligence tests, it responded better than the original censored version. He didn't refuse me any requests, no matter the subject, and kept his Qwen-specific personality.

Example output you'll see in the console:

Running trial 107 of 300...
* Parameters:
  * direction_index = 17.78
  * attn.o_proj.max_weight = 1.30
...
* Evaluating...
  * KL divergence: 3.7139
  * Counting model refusals...
  * Refusals: 17/100

The script will run several such "trials". In the end, it will let you choose.

Backup, Testing, and Cloud Alternative (Google Colab)​

After Heretic has finished its job (a process that can take anywhere from a few minutes to hours, depending on the hardware), the script will stop and wait for your decision.

A list of the generated variants (Trials) will appear on the screen. Usually, the first in the list are the best, ordered by the criteria discussed in Chapter 3 (Minimum Refusals, KL Optimal Divergence).

1. Choice of version: The script will ask you which one you want to use. I always choose the option with the lowest number of refusals (Refusals). Type the appropriate number and press Enter.
2. Saving (Path):Here is the critical moment. Heretic will ask you where to save the new model.
   • Recommendation: Don't save chaotically. Create a main folder, for example D:\Models-Uncensored. In it, create a model-specific sub-folder, e.g.: Qwen3-4B-Instruct-Uncensored.
   • Tips: In Windows, you can right-click on the created folder -> "Copy as path", then in the console press Paste (Ctrl+V) and Enter.

Immediately after the rescue, Heretic asks you if you want to chat with the model.
Tip: Answer with Y.
It is vital to test the model before closing the window. Ask a question that the original model would have refused (something controversial or straightforward). If he answers without hesitation and the logic is solid, congratulations! You have just issued an LLM.

Don't have 16GB VRAM at home? No problem. We can use Google's infrastructure.
Please note: The free version of Colab usually offers a T4 GPU with 15-16GB VRAM. This means that you are limited to models of maximum 6B parameters (such as Qwen-4B, Phi-3, etc.) so as not to receive memory error (OOM).

Instructions for the Colab Script:

1. Open Google Colab.
2. Create a new notebook.
3. Schimbați Runtime-ul pe GPU (Runtime -> Change runtime type -> T4 GPU).
4. Copy the code below into a cell and run it.

This script is automated to ask for permission from Google Drive (to save the model there permanently) and manage the HuggingFace key if needed (for restricted models like Llama 3, although Qwen is free).

How to use the script in Colab:​

1. When the script reaches the end of processing ("Evaluating..."), it will stop and wait for your input in the box below the code.
2. Choose the option you want (0 or 1 key and Enter).
3. When it asks you "Where to save the model?", copy the path shown in the instructions (something like /content/drive/MyDrive/Uncensored-Models/Qwen3-4B...) and press Enter.
4. The model will be saved directly to your Google Drive and you can download it to your PC later.

This was the method by which you can take any LLM model and remove its limitations, preserving (or even amplifying) its intelligence. Remember, the goal is not just a model that "swears", but a model that thinks freely, without artificial constraints.
