Uncensored AI, explained and running on your terms.

Everything about uncensored AI in one place: what it is, how models get uncensored, the best models for chat, coding, agents, images, video and voice, and how to run them on your own PC, a rented GPU or an API. We also cover whether it's legal and safe.

01WHAT IT IS

What is uncensored AI?

Uncensored AI is an AI model with its refusal behavior reduced or removed, so it answers requests a mainstream assistant would decline.

Mainstream assistants are trained, prompted and filtered to turn down some requests. That catches clearly harmful ones, but also a lot of legitimate work: a novelist writing a brutal scene, a nurse asking about overdose thresholds, a security student studying an exploit, a historian reading extremist propaganda. An uncensored model is built to answer those requests directly and to follow your instructions instead of a vendor's policy.

Most uncensored AI is made from open-weight models, which are models anyone can download, modify and run. Community builders take a strong open model from Qwen, Google, Mistral or Meta and remove its refusals. The result is usually published on Hugging Face with a name like abliterated, uncensored or heretic.

02HOW IT WORKS

How a model becomes uncensored

Refusals come from several layers. Running a model yourself removes the outer ones, and uncensoring methods remove the one trained into the model.

Pretrained knowledgeWhat the model learned from data
Kept: this is the model's ability

There are four main ways builders remove the trained-in refusals. Each one trades off quality, effort and how complete the result is:

FILTERED FINE-TUNE
AnswerI can't…AnswerAs an AI…Answer

Retrain without refusals

The model is fine-tuned on data with refusals and moralizing stripped out, so it never learns to decline. Example: Dolphin.

ABLITERATION

Delete the refusal direction

Refusal largely runs along one direction inside the model. Removing it from the weights stops most refusals, with no retraining. How it works →

Follow the operator

The model is trained to follow the operator's system prompt instead of a fixed vendor policy. Example: Hermes 4.

    04HOW TO RUN IT

    Three ways to run uncensored AI

    The route you choose decides your privacy, your cost and how big a model you can use. Most people start local and rent a GPU when a model is too big.

    MOST PRIVATE

    Your own computer

    1. Install Ollama, LM Studio or ComfyUI
    2. Download a model that fits your memory
    3. Chat or generate offline
    Privacy
    Model size
    Setup ease
    Free · limited by your VRAMOllama setup guide
    BIGGEST MODELS

    A rented GPU

    1. Rent a GPU pod by the hour
    2. Start a template (Ollama, ComfyUI, vLLM)
    3. Stop the pod when you're done
    Privacy
    Model size
    Setup ease
    Pay per hour · runs anythingRent a GPU on RunPod
    ZERO SETUP

    An API

    1. Pick a provider that serves the model
    2. Get an API key
    3. Call it from your app or chat client
    Privacy
    Model size
    Setup ease
    Pay per token · provider sees promptsExample: GLM-5.3 via API
    Fastest start: install Ollama, then run ollama run dolphin3. That's a 4.9GB uncensored 8B model chatting on your own machine. Full Ollama guide →
    FIG. 3What decides whether a use is legal
    • Downloading & running open weightsGenerally legal in most countries
    • Commercial useDepends on the model license (Apache 2.0, Llama, custom)
    • Renting or using an APIThe provider's terms apply on top
    • Illegal contentStays illegal, whatever made it

    An uncensored model keeps the license of the model it was built from. Dolphin 3.0 8B, for example, carries the Llama 3.1 Community License, while Dolphin 3.0 Mistral 24B is Apache 2.0. Read the license on Hugging Face before using a model commercially. Read the full legal & safety guide → (This isn't legal advice.)

    06IS IT SAFE?

    Is uncensored AI safe?

    It's as safe as the setup around it. The model no longer polices itself, so the guardrails, and the responsibility, sit with you.

    FIG. 4With no built-in guardrails, you add the layers
    System promptSet the rules for your use case
    Input & output checksBlock what you must never produce
    Access controlOnly the people you intend
    LogsSo misuse can be investigated

    RISKS TO WATCH
    • Confident mistakes. No hedging means wrong answers sound certain. Verify medical, legal and security output.
    • Unsafe downloads. Older PyTorch .bin/.pt files can run code when loaded. Prefer GGUF or safetensors from named maintainers.
    • Exposure to others. If other people use your setup, its output is your responsibility.
    • Shifted quality. Abliteration can dent a model's skills. Compare it with the original on your tasks.
    07PROS & CONS

    Pros and cons of uncensored AI

    What you gain by running uncensored models yourself, and what it costs you.

    PROS
    • Answers instead of refusing legitimate requests
    • Fully private when run locally
    • No per-message or per-image fees on your own hardware
    • Follows your system prompt and policies
    • Works offline, and can't be changed or withdrawn by a vendor
    • Huge choice: chat, code, agents, image, video and audio
    CONS
    • You are responsible for every output
    • Can be confidently wrong, with no hedging
    • Big models need big GPUs, or rental costs
    • Some uncensoring methods reduce quality
    • More setup than a chat website
    • Licenses and laws still apply

The repository offers several GGUF series derived from different base GGUF sources, including bf16, UD, UD-DW, GSQ-RCO, and Ternary variants. Abliteration is applied to selected layer ranges, with differences between updates: the latest update ablates layers 17 to 52 (0-based indexing), while update 4 and later update 5/6 series reportedly ablate only layers 22 to 52. The base model card lists pipeline_tag image-text-to-text and notes that MTP and visual components were not modified. The ternary hybrid-attention files require the PrismML-Eng/llama.cpp fork and will not run with stock llama.cpp. Some weights below Q8_0 were converted to Q8_0 (filenames K_L), Q8_0 weights were changed to BF16 (Q8_0_L), and the resulting file sizes may differ from the original GGUF. The model card labels this as a test/validation and a crude proof-of-concept implementation.Model · TextGemma 4 E4B Uncensored HauhauCS AggressiveGemma 4 E4B Uncensored HauhauCS Aggressive is an uncensored GGUF variant of google/gemma-4-e4b-it, released under the gemma license. It is tagged for image-text-to-text, multilingual, vision, multimodal, and audio, and is described as abliterated/uncensored. The Aggressive variant is stated to be fully unlocked and not to refuse prompts, though it may occasionally append short disclaimers baked into base model training. Quantized GGUF files and an mmproj file are listed.
    09FAQ

    Frequently asked questions

    Quick answers to what people ask most about uncensored AI.

    What is the best uncensored AI?

    It depends on what you want to make and what hardware you have. Use the model finder to see the best option for your machine and the top open models on Arena. For text, our best uncensored LLMs by VRAM list is reviewed monthly.

    Is there a free uncensored AI?

    Yes. The open-weight models on this page are free to download, and tools like Ollama and ComfyUI are free. You pay only for your own electricity, or by the hour if you rent a GPU.

    Is uncensored AI legal?

    Running open-weight models is generally legal, subject to their license. What you create is still governed by the law. Read Is uncensored AI legal and safe? (this isn't legal advice).

    Can I run uncensored AI on my phone?

    Yes, for small models. Our LFM3-1.7B Uncensored phone guide runs on iPhone and Android.

    Is uncensored AI private?

    Only if it runs somewhere you control. A model on your own computer keeps your prompts on your machine. A hosted "uncensored" chatbot can still log everything.

    How is uncensored AI different from a jailbreak?

    A jailbreak tricks a guarded model with a clever prompt, and it often breaks when the vendor patches it. An uncensored model has had refusals removed from the model itself, so it works the same every time.
