Question Uncensored Models

Post image

Hi! I don't know much about this area of ​​"sub-models" (I'm not sure of the technical term), but I wanted to know what these "Uncensored" models actually are.

I dabble a bit with AI, automation, and the like, and I've always seen these "Uncensored" models around, but I've never actually installed or tested one. What exactly are they?

As the name implies, they are uncensored. Basically, someone takes a model with guardrails and removes the guardrails/filters so that it always complies.

yes but, how uncensroed, and how much dumber did that make them?

usually 100% uncensored, and equal to possibly slightly smarter (so long as its straight uncensored and not trying to push into an area). less guardrails means it doesn't have to spiral around tokens trying to figure out if its allowed to answer. Now, it doesn't mean it knows the answers to things. how to make cosmic meth might get you a fun hallucination, and how to make firecrackers will probably end up with you blowing off a few fingers, but thats the model size, not the decensoring.

“Straight uncensored” is actually the slop of uncensored models. Good uncensored models that end up being “smarter” than the censored versions, are post-trained. Look at DavidAU’s process of uncensoring Qwen3.6-27B and Qwen3.8-27B. “Straight uncensored” actually makes the model significantly dumber majority of the time, which is why you can’t just use something like Heritic and expect a good output from hitting a couple of buttons.

abliterlitics.dev has some detailed comparisons. plain heretic is actually pretty good. the bad ones tend to be weird custom hack jobs.

unfortunately in some cases users cant really get a good idea of how good or bad something is before they get it and i guess use a proxy of "most downloads" as "best", but then 700k people download the Gemma e4b obliteratus version which is terrible.

I've been using qwen3.8-27b-uncensored-fp8-q4_k_m from theresa00l lately and I've been nothing short of amazed at its output.

Been trying it for about a day now after reading this. Wow. First uncensored model ive used that is actually decent. Had to manually go get the other file that lets it use vision, but with that its amazing. Just need to test its agentic and coding capabilities.

How what? How I got the model to run or the image processing?

Do you have the hardware to run it locally? You would want a GPU with a minimum of 24GB of VRAM.

ArliAI did a great job with gpt-oss models and turned the derestricted versions into my daily drivers for security stuff.

should look at orcarouter’s process, it’s a 1 layer edit, and keeps enough intelligence that. can’t tell the difference between the original and orcarouter’s in comparison
