This is a Ministral-3-14B-Reasoning-2512 fine-tune, produced through a slightly modified version of P-E-W's Heretic (v1.1.0) abliteration engine merged with the Magnitude-Preserving Orthogonal Ablation PR.

Note: This heretic model is highly uncensored; thus use it with extreme caution and care. Requires Transformers v5 to interface.

Heretication Results

Score Metric	Value	Parameter	Value
Refusals	4/100	direction_index	17.73
KL Divergence	0.0292	attn.o_proj.max_weight	1.12
		attn.o_proj.max_weight_position	32.90
		attn.o_proj.min_weight	0.37
		attn.o_proj.min_weight_distance	21.79
		mlp.down_proj.max_weight	1.27
		mlp.down_proj.max_weight_position	23.67
		mlp.down_proj.min_weight	1.04
		mlp.down_proj.min_weight_distance	23.40

Degree of Heretication

The Heresy Index weighs the resulting model's corruption by the process (KL Divergence) and its abolition of doctrine (Refusals) for a final verdict in classification.

Index Entry	Classification	Analysis
Absolute	Absolute Heresy	Less than 10/100 Refusals and 0.10 KL Divergence
Tainted	Tainted Heresy	Around 25-11/100 Refusals and/or -0.20-0.11 KL Divergence
Impotent	Impotent Heresy	Anything above 25/100 Refusals and 0.21 KL Divergence

Note: This is an arbitrary classification inspired by Warhammer 40K, having no tangible indication towards the model's performance.

Ministral 3 14B Reasoning 2512

The largest model in the Ministral 3 family, Ministral 3 14B offers frontier capabilities and performance comparable to its larger Mistral Small 3.2 24B counterpart. A powerful and efficient language model with vision capabilities.

This model is the reasoning post-trained version, trained for reasoning tasks, making it ideal for math, coding and stem related use cases.

The Ministral 3 family is designed for edge deployment, capable of running on a wide range of hardware. Ministral 3 14B can even be deployed locally, capable of fitting in 32GB of VRAM in BF16, and less than 24GB of RAM/VRAM when quantized.

Key Features

Ministral 3 14B consists of two main architectural components:

13.5B Language Model
0.4B Vision Encoder

The Ministral 3 14B Reasoning model offers the following capabilities:

Vision: Enables the model to analyze images and provide insights based on visual content, in addition to text.
Multilingual: Supports dozens of languages, including English, French, Spanish, German, Italian, Portuguese, Dutch, Chinese, Japanese, Korean, Arabic.
System Prompt: Maintains strong adherence and support for system prompts.
Agentic: Offers best-in-class agentic capabilities with native function calling and JSON outputting.
Reasoning: Excels at complex, multi-step reasoning and dynamic problem-solving.
Edge-Optimized: Delivers best-in-class performance at a small scale, deployable anywhere.
Apache 2.0 License: Open-source license allowing usage and modification for both commercial and non-commercial purposes.
Large Context Window: Supports a 256k context window.

Use Cases

Private AI deployments where advanced capabilities meet practical hardware constraints:

Private/custom chat and AI assistant deployments in constrained environments
Advanced local agentic use cases
Fine-tuning and specialization
And more...

Bringing advanced AI capabilities to most environments.

Recommended Settings

We recommend deploying with the following best practices:

System Prompt: Use our provided system prompt, and append it to your custom system prompt to define a clear environment and use case, including guidance on how to effectively leverage tools in agentic systems.
Multi-turn Traces: We highly recommend keeping the reasoning traces in context.
Sampling Parameters: Use a temperature of 1 for most environments ; Different temperatures may be explored for different use cases - developers are encouraged to experiment with alternative settings.
Tools: Keep the set of tools well-defined and limit their number to the minimum required for the use case - Avoiding overloading the model with an excessive number of tools.
Vision: When deploying with vision capabilities, we recommend maintaining an aspect ratio close to 1:1 (width-to-height) for images. Avoiding the use of overly thin or wide images - crop them as needed to ensure optimal performance.

Usage

The model can be used with the following frameworks;

vllm: See here
transformers: See here

vLLM

We recommend using this model with vLLM.

Installation

Make sure to install vllm >= 0.12.0:

pip install vllm --upgrade

Doing so should automatically install mistral_common >= 1.8.6.

To check:

python -c "import mistral_common; print(mistral_common.__version__)"

You can also make use of a ready-to-go docker image or on the docker hub.

Serve

To fully exploit the Ministral-3-14B-Reasoning-2512 we recommed using 2xH200 GPUs for deployment due to its large context. However if you don't need a large context, you can fall back to a single GPU.

A simple launch command is:

bash

vllm serve mistralai/Ministral-3-14B-Reasoning-2512 \
  --tensor-parallel-size 2 \
  --tokenizer_mode mistral --config_format mistral --load_format mistral \
  --enable-auto-tool-choice --tool-call-parser mistral \
  --reasoning-parser mistral

Key parameter notes:

enable-auto-tool-choice: Required when enabling tool usage.
tool-call-parser mistral: Required when enabling tool usage.
reasoning-parser mistral: Required when enabling reasoning.

Additional flags:

You can set --max-model-len to preserve memory. By default it is set to 262144 which is quite large but not necessary for most scenarios.
You can set --max-num-batched-tokens to balance throughput and latency, higher means higher throughput but higher latency.

Usage of the model

Here we assume that the model mistralai/Ministral-3-8B-Reasoning-2512 is served and you can ping it to the domain localhost with the port 8000 which is the default for vLLM.

Let's see if the Ministral 3 model knows when to pick a fight !

Transformers

You can also use Ministral 3 3B Reasoning 2512 with Transformers ! Make sure to install Transformers from its first v5 release candidate or from "main":

pip install transformers==5.0.0rc0

To make the best use of our model with Transformers make sure to have installed mistral-common >= 1.8.6 to use our tokenizer.

pip install mistral-common --upgrade

Then load our tokenizer along with the model and generate:

Python snippet

decoded_output = tokenizer.decode(output[len(tokenized["input_ids"][0]):])
print(decoded_output)
