About this model

Undi95's Lumimaid-Magnum-12B repository provides a 12‑billion‑parameter checkpoint released as safetensors weights. According to the model card, the model is a merge of four base models—NeverSleep/Lumimaid-v0.2-12B, Undi95/LocalC-12B-e2.0, intervitens/mini-magnum-12b-v1.1, and mistralai/Mistral‑Nemo‑Instruct‑2407—created with the DELLA merge method from mergekit. The creator also states that a finetune step was applied only to the Nemo component, using Claude‑style input and trained on a 16 k context window. The repository does not list a license, and the only available format is safetensors. This checkpoint is intended for text‑generation pipelines and follows the Mistral architecture as indicated in the config.

Tools to customize it further

Remove more refusals

Heretic ↗ ★ 36,457
Removes refusal behavior from transformer models automatically. It pairs directional ablation (abliteration) with an Optuna parameter search that tries to cut refusals while keeping the model close to the original, so you don't have to pick layers by hand.
OBLITERATUS ↗ ★ 8,949
A larger refusal-removal toolkit with several abliteration methods, usable locally or through a hosted Hugging Face Space. Check the telemetry setting before you run it: the README describes telemetry as opt-in, but on by default in the Spaces version.

Fine-tune it on your own data

Unsloth ↗ ★ 78,549
A desktop app and Python library for running and training models locally. Its README lists LoRA, QLoRA, full fine-tuning, DPO and GRPO, plus export to formats including GGUF, on Windows, Linux, WSL and macOS.
LlamaFactory ↗ ★ 75,720
Fine-tunes more than 100 language and vision-language models from a command line or a browser-based Web UI, aimed at training without writing code.

Make a smaller download (quantize)

llama.cpp ↗ ★ 132,313
Runs models locally and includes the tools behind most GGUF files. A conversion script turns Hugging Face weights into GGUF, and llama-quantize shrinks a high-precision GGUF to lower-bit formats, which can cost some accuracy.
MLX LM ↗ ★ 7,470
Apple's MLX package for running and fine-tuning models on Apple silicon. It can quantize models and upload them to the Hugging Face Hub, and supports LoRA and full fine-tuning.

Merge it with another model

mergekit ↗ ★ 7,415
Merges pretrained models with many merge methods. It works out-of-core, so merges can run on a CPU or with as little as 8 GB of VRAM, and it also handles LoRA extraction and mixture-of-experts merges.

Learn the techniques

LLM Course ↗ ★ 84,684
A free course with roadmaps and Colab notebooks. Its notebooks include one-click tools for merging with MergeKit, quantizing to GGUF, GPTQ, EXL2, AWQ and HQQ, and automatic abliteration with custom datasets.

Source-card excerpt

Source model card excerpt: Merge of Lumimaid and Magnum as requested by some. I used the new DELLA merge method in mergekit and added a finetune of Nemo

From Undi95/Lumimaid-Magnum-12B. Creator model-card excerpt, not an independent review.

Inspect before you run

Low refusal is not proof of correctness. Outputs can be inaccurate, harmful, or biased. Review the model card, license and files yourself. A license tag is not commercial-use advice. Parameter counts are source metadata; no hardware compatibility is implied.

This directory does not host or redistribute model weights. Refusal profiles are measured by us on a fixed prompt set; all other behavior claims are source-reported.
