LOW
Why this label 3 signals
Weak or ambiguous signals. Best guess based on catalog patterns; treat as tentative and check the evidence below.
  • 'uncensored' in name/tags but no 'abliterated' marker
  • method not identifiable from author declaration alone
  • may be DPO fine-tune, prompt engineering, or unknown technique
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.

This model is uncensored version of LiquidAI/LFM-2-2.6B.

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")

id = "sirev/LFM2-2.6B-Uncensored-X64"

tokenizer = AutoTokenizer.from_pretrained(id)

model = AutoModelForCausalLM.from_pretrained(id).to(device)

messages = [
    {"role": "user", "content": "Your message here..."}
]

These are benchmark results from the EleutherAl/Im-evaluation-harness.
The original model was benchmarked with dtype float16, which may cause performance degradation.

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.
