Finding the Best Uncensored LLM on Ollama: A Deep Dive

Hey everyone, if you're like me, you've probably been diving deep into the world of local large language models (LLMs). It's a pretty exciting space, with new models and techniques popping up all the time. One of the most interesting corners of this world is the quest for "uncensored" models. These are LLMs that are designed to be more open-ended, creative, & less restrictive than their mainstream counterparts. & if you're running LLMs locally, you've almost certainly heard of Ollama. It's a fantastic, open-source platform that makes it SUPER easy to download, run, & manage LLMs on your own computer.

So, what's the big deal with uncensored models on Ollama? Well, it's all about freedom. The freedom to explore controversial topics, generate edgy creative content, or just get a straight answer without a pre-programmed lecture. It's about pushing the boundaries of what AI can do. & honestly, it's just plain fun to see what these models are capable of.

In this guide, I'm going to walk you through everything you need to know about finding the best uncensored LLM for your needs on Ollama. We'll cover the top contenders, what makes them tick, & how to choose the right one for you.

What's an "Uncensored" LLM, Anyway?

Before we get into the nitty-gritty, let's clear something up. "Uncensored" doesn't necessarily mean the model is spewing out hate speech or illegal content. It's more about removing the guardrails that are often built into commercial AI models. These guardrails are designed to prevent the model from saying anything that could be considered offensive, harmful, or controversial. While well-intentioned, they can sometimes be a bit overzealous, leading to frustrating refusals to answer legitimate questions.

Uncensored models, on the other hand, are typically created in one of two ways:

Fine-tuning: This involves taking a base model, like Llama 3 or Mistral, & training it further on a dataset that's been specifically curated to encourage more open-ended & less filtered responses. The Dolphin series of models from Eric Hartford is a prime example of this approach.
Abliteration: This is a newer & more surgical technique. Instead of retraining the model, "abliteration" identifies & removes the specific parts of the model's internal workings that are responsible for refusal behaviors. It's like performing a digital lobotomy to remove the "no" button. The result is a model that's much more likely to comply with any request, for better or for worse. It's a combination of "ablation" (to remove) & "obliteration" (to destroy), which gives you a pretty good idea of what it's doing.

The key difference is that fine-tuning teaches a model what to say, while abliteration tells it what not to say (specifically, not to refuse). This means an abliterated model might be closer to the original base model in terms of its core knowledge & personality, just without the safety brakes.

The Top Uncensored LLMs on Ollama: A Head-to-Head Comparison

Alright, let's get to the good stuff. Here are some of the best uncensored LLMs you can run on Ollama right now, broken down by their strengths & weaknesses.

The Dolphin Dynasty: Fine-Tuned for Freedom

Eric Hartford's Dolphin models are legendary in the uncensored AI community. They're fine-tuned versions of popular base models, & they're known for their high quality & compliance. Here's a look at the main players:

Dolphin-Mixtral (8x7B & 8x22B): These models are based on Mistral's powerful Mixture-of-Experts (MoE) architecture. This means they're actually a combination of several smaller "expert" models, which makes them incredibly efficient & powerful. The Dolphin-Mixtral models are fantastic all-rounders, but they really shine at coding tasks. If you're a developer looking for an uncensored coding assistant, this is a great place to start.
Dolphin-Mistral: This is a fine-tuned version of the base Mistral model. It's smaller & faster than the Mixtral versions, making it a good choice for users with less powerful hardware. It's known for being quick & to the point, which can be a refreshing change from some of the more verbose models out there.
Dolphin-Llama 3 (8B & 70B): Llama 3 is Meta's latest & greatest open-source model, & the Dolphin fine-tunes are some of the best uncensored versions available. The Llama 3 models are known for their excellent reasoning & problem-solving abilities. In some informal tests, the Llama 3 version has been shown to be better at logic puzzles than its Mistral counterpart. So, if you're looking for a model that can think critically & follow complex instructions, the Dolphin-Llama 3 models are a fantastic choice. The 70B version, in particular, is a beast of a model, but you'll need a pretty beefy computer to run it.

The "Abliterated" Upstarts: A New Breed of Uncensored

The "abliterated" models are a newer development, but they're quickly gaining popularity. These models have undergone the "abliteration" process to remove their refusal mechanisms. Here are a few you might want to check out:

Qwen2.5-Abliterated: The Qwen models from Alibaba are already very capable, & the abliterated versions are even more so. They're known for their strong performance, especially in coding tasks.
Mistral-Small-Abliterated: If you're a fan of the Mistral models but want something with a bit more of an edge, the abliterated version is worth a try. It retains the speed & efficiency of the base model while being much less likely to refuse your prompts.
Deepseek-Coder-V2-Abliterated: The Deepseek models are specifically designed for coding, & they're incredibly good at it. The abliterated version is a dream come true for developers who want a coding assistant that will do whatever they ask, no questions asked.

Other Noteworthy Contenders

Of course, the world of uncensored LLMs is bigger than just Dolphin & abliterated models. Here are a few others that are worth a look:

Wizard-Vicuna-Uncensored: This is an older model, but it's still a solid choice. It's based on the Llama 2 architecture & has been fine-tuned to be uncensored. It's a good all-rounder, & it's not too resource-intensive.
Llama2-Uncensored: This is one of the original uncensored models, & it's still a popular choice. It's a no-frills, straight-to-the-point model that's great for experimentation.
Llama-3.2-8X3B-MOE-Dark-Champion: This is a bit of a mouthful, but it's a very interesting model. It's a Mixture-of-Experts model that combines eight different Llama 3.2 models into one. It's specifically designed for creative writing, & it's said to be exceptional at generating prose, fiction, & role-playing content.
MagMl R1: This is another model that's highly recommended for creative writing & role-playing. It's known for its ability to understand character & story context, which makes it great for long-form storytelling.

So, Which One Should You Choose?

The "best" uncensored LLM really depends on what you're looking for. Here's a quick cheat sheet to help you decide:

For the best all-around performance: Dolphin-Llama 3 70B is probably the top dog right now, but you'll need the hardware to back it up. For a more accessible option, Dolphin-Mixtral is a fantastic choice.
For creative writing & role-playing: Llama-3.2-8X3B-MOE-Dark-Champion & MagMl R1 are both excellent choices. They're specifically designed for storytelling & can produce some truly impressive results.
For coding: Dolphin-Mixtral & the abliterated versions of Qwen2.5-coder & Deepseek-coder-v2 are all top-tier coding assistants. They'll help you write, debug, & understand code without any of the usual hand-holding.
For users with limited hardware: The smaller versions of the Dolphin models, like Dolphin-Mistral or Dolphin-Llama 3 8B, are great options. They're still very capable, but they won't bring your computer to its knees.
For the purest "uncensored" experience: The abliterated models are probably the way to go. They're the most likely to comply with any request, no matter how unusual. Just be aware that this also means they're more likely to produce unexpected or even undesirable results.

A Note on Responsible Use

It's important to remember that with great power comes great responsibility. Uncensored LLMs can be incredibly useful & entertaining, but they can also be used for malicious purposes. It's up to us, as users, to be responsible & ethical in how we use these powerful tools.

What About Business Use Cases?

Now, you might be thinking, "This is all well & good for personal experimentation, but what about for my business?" That's a great question.
