Primary method

Repackaging (quantization)

Applied on top of direct removal inherited from the base model.
Confidence
HIGH
Inherited from base model
Why this label 3 signals
Producer identity confirmed by naming conventions, tags or the model card. This label is very unlikely to change.
  • author=mradermacher (M8 quantization producer, never originator)
  • is_gguf=1
  • base_model='zaakirio/LFM2.5-1.2B-Instruct-Uncensored' (base has 'abliterated' marker, assume M1 default)
Refusal direction extraction

No specific extraction method could be identified for this model. The producer either did not document it or used a proprietary pipeline.

About

weighted/imatrix quants of https://huggingface.co/zaakirio/LFM2.5-1.2B-Instruct-Uncensored

For a convenient overview and download list, visit our model page for this model.

static quants are available at https://huggingface.co/mradermacher/LFM2.5-1.2B-Instruct-Uncensored-GGUF

Usage

If you are unsure how to use GGUF files, refer to one of TheBloke's
READMEs
for
more details, including on how to concatenate multi-part files.

Provided Quants

(sorted by size, not necessarily quality. IQ-quants are often preferable over similar sized non-IQ quants)

Link Type Size/GB Notes
GGUF imatrix 0.1 imatrix file (for creating your own quants)
GGUF i1-IQ1_S 0.4 for the desperate
GGUF i1-IQ1_M 0.4 mostly desperate
GGUF i1-IQ2_XXS 0.5
GGUF i1-IQ2_XS 0.5
GGUF i1-IQ2_S 0.5
GGUF i1-IQ2_M 0.5
GGUF i1-Q2_K_S 0.6 very low quality
GGUF i1-Q2_K 0.6 IQ3_XXS probably better
GGUF i1-IQ3_XXS 0.6 lower quality
GGUF i1-IQ3_XS 0.6
GGUF i1-IQ3_S 0.7 beats Q3_K*
GGUF i1-Q3_K_S 0.7 IQ3_XS probably better
GGUF i1-IQ3_M 0.7
GGUF i1-Q3_K_M 0.7 IQ3_S probably better
GGUF i1-Q3_K_L 0.7 IQ3_M probably better
GGUF i1-IQ4_XS 0.8
GGUF i1-IQ4_NL 0.8 prefer IQ4_XS
GGUF i1-Q4_0 0.8 fast, low quality
GGUF i1-Q4_K_S 0.8 optimal size/speed/quality
GGUF i1-Q4_K_M 0.8 fast, recommended
GGUF i1-Q4_1 0.9
GGUF i1-Q5_K_S 0.9
GGUF i1-Q5_K_M 0.9
GGUF i1-Q6_K 1.1 practically like static Q6_K

FAQ / Model Request

See https://huggingface.co/mradermacher/model_requests for some answers to
questions you might have and/or if you want some other model quantized.

Thanks

I thank my company, nethype GmbH, for letting
me use its servers and providing upgrades to my workstation to enable
this work in my free time. Additional thanks to @nicoboss for giving me access to his private supercomputer, enabling me to provide many more imatrix quants, at much higher quality, than I would otherwise be able to.

Catalog is the map. Apps are the tools.

Run models on your own machine, not in the cloud.

Every model page has an "Open in Abliteration" button that hands the model directly to the first-party desktop client, at the quantization your rig can actually run. No API keys, no subscription, no prompt leakage.
