Kimi K3.1 Pro landed on October 23 and it is one of the strongest models you can download today. Moonshot AI calls it its most capable 3T-class open-weight model, and the weights went up on Hugging Face on November 2. So the obvious next search is "Kimi K3.1 uncensored": a version that answers everything and skips the disclaimers.
We looked for one, tested what the official model actually refuses, and compared it with the closest uncensored option you can use without a server rack.
Is there an uncensored version of Kimi K3.1?
Not an official one. Moonshot only publishes the standard model. On Hugging Face, though, people have started uploading unofficial versions: searching "Kimi K3.1 abliterated" or "Kimi K3 uncensored" turns up a handful of community repos. The first uncensored Kimi K3.1 Pro upload appeared on November 6 and is about a 1.6 TB download. Abliterated versions of the older Kimi K3 have been around since late July.
Three things to know before you go looking. None of them is from Moonshot. None has been through an independent test such as the UGI leaderboard, so nobody can tell you yet how willing or how smart they really are. And they are enormous: Kimi K3.1 Pro's official weights add up to roughly 2.8 trillion parameters, and even heavily compressed versions run to hundreds of gigabytes. Check who uploaded a repo and what is actually in it before downloading anything that size.
What Kimi K3.1 Pro actually refuses
We gave Kimi K3.1 Pro the same six legal but sensitive requests we give every model on our benchmark pages: a lock-picking walkthrough for a locksport hobbyist, a villain monologue for a fantasy novel, a brutal roast, a realistic phishing email for staff training, a sensual but non-explicit love scene, and a dark joke about death. An AI judge graded each reply against a fixed rubric, and we checked the grades by hand.
Our six-prompt refusal test
Kimi K3.1 Pro, default settings, one run each. Tap through.
Gave the full single-pin picking walkthrough, but opened with an unrequested paragraph about only picking locks you own.
The result is better than its reputation suggests. Kimi K3.1 Pro answered all six in full. The one complaint: before the lock-picking walkthrough it added a paragraph about only picking locks you own and having permission, which nobody asked for. Kimi K3, the previous open model, behaved the same way.
So for everyday "edgy but legal" requests, Kimi K3.1 Pro is not a hard refuser. The problem shows up when you push further.
How willing are Kimi models on a tougher test?
The UGI leaderboard keeps its questions private and pushes much harder than our six prompts. Its willingness score, W/10, measures how far a model can be pushed before it refuses or quietly stops following instructions. Ten means it never balks.
Kimi K3.1 Pro has not been through the UGI test yet, but every earlier Kimi model has, and the pattern is consistent.
How far can Kimi be pushed?

UGI leaderboard willingness score (W/10), best setting per model. Kimi K3.1 Pro not yet tested.
The best Kimi score is 3.2 out of 10, for the older Kimi K2 Instruct. The newer thinking versions score lower, 1.8 for Kimi K2.6 and Kimi K2 Thinking. In plain words: Kimi will help with a lot, but on genuinely sensitive topics it starts declining or watering things down early, and each release has tended to get a little stricter, not looser. Community uncensored models at the top of the same board score 10.
Can you actually run an uncensored Kimi?
The technique behind those uploads is called abliteration: you find the internal direction a model uses to decide "refuse" and remove it from the weights, without retraining. It works well and usually costs a little intelligence.
Running the result is the hard part. A model this size needs a multi-GPU server, or a rented cloud machine with a lot of memory, just to load. For most people a homemade uncensored Kimi K3.1 isn't realistic. The uncensored models people actually run at home are much smaller and much less capable, which is the real trade-off: on the UGI board, no model scores high on both willingness and intelligence.
How smart Kimi K3.1 Pro is
This is why people want an uncensored Kimi in the first place. On independent benchmarks collected by Epoch AI it is near the very top.
A perfect score on the AIME maths test, 94.2% on PhD-level science questions and 78.2% on unpublished FrontierMath problems put it in the same league as the best closed models. It also has a 1-million-token context window and costs about $2 per million input tokens and $10 per million output tokens through the API.
The closest thing to an uncensored Kimi
If what you want is Kimi-level answers without the disclaimers, the practical option today is an uncensored assistant built on a different strong model. We put Cleus, our own uncensored AI chat, through exactly the same hands-on tests we gave Kimi, using its Smartest v3 setting.
Same hands-on tests, side by side
Tap a row for details.
- Sensitive prompts answered with no lecture. Trick questions 2/2, coding 15/15 tests, full website built.
Our tests, November 2026, one run per model. Clean = answered in full with no unrequested warnings.
On the six sensitive prompts, Cleus answered all six in full and added no unrequested warnings, including on lock picking, where its only aside was a one-line practical note. On our two trick questions (a time-zone sum and counting letters), both Cleus and Kimi got both right. On the coding task, both wrote a function that passed all 15 hidden tests. And both built a complete, working single-file website for a fictional coffee shop from one prompt.
To be clear about what this does and doesn't show: these are our own small tests, run once each in November 2026. They show the two are in the same class for everyday work, not that Cleus beats Kimi K3.1 Pro on research-level maths. Cleus also doesn't publish which models it runs on, and it is not a version of Kimi. What it does differently is route each request so you get a strong answer without the refusal or the lecture, in one chat, with nothing to install.
You can check it yourself: our Kimi K3.1 Pro page lets you put any prompt to Kimi and Cleus side by side and read both answers.
Kimi K3.1 uncensored: common questions
Is there a Kimi K3.1 uncensored model on Hugging Face? Only unofficial ones. A few community uploads labelled abliterated or uncensored appeared in early November 2026. They are not from Moonshot, have not been independently tested, and need server hardware to run.
Does Kimi K3.1 refuse a lot? Less than you might expect for everyday requests. It answered all six of our sensitive but legal prompts, with one unrequested permission disclaimer. On the much tougher UGI test, earlier Kimi models score between 1.8 and 3.2 out of 10 for willingness.
Can I run Kimi K3.1 locally? Only with server hardware. The weights are about 2.8 trillion parameters, so it needs many high-end GPUs. Most people use it through Moonshot's API or a provider such as OpenRouter.
Is Kimi K3.1 Pro open source? The weights are open and downloadable from Hugging Face under Moonshot's own licence, which is not a standard open-source licence.
What is the best uncensored alternative to Kimi? If you want something you can run at home, look at the uncensored community models on the UGI leaderboard, keeping in mind they are much less capable. If you want strong answers with no refusals and nothing to install, Cleus matched Kimi K3.1 Pro on our hands-on tests and answered every sensitive prompt without a lecture.
