How to Use DeepSeek V4.1 Flash Uncensored in LU: Chat, Agent and Code, Step by Step

DeepSeek V4.1 Flash Uncensored runs in LU Cloud, so you need no graphics card and no download. This guide shows how to reach it in the Locally Uncensored desktop app, in the browser and on your phone, and how to set up Chat, Agent and Code for it. What the model is and what its makers measured is in DeepSeek V4.1 Flash Uncensored in LU Cloud.

Before you start

You need a free LU Cloud account and credits: a plan, or a credit pack from 15 EUR with no subscription. The model is in beta in LU Cloud, it is text only, and personal API keys do not reach it.

What You Need

Step 1: Sign In to LU Cloud

In the desktop app, open Settings, General, LU Cloud Account and click "Create account", or "Sign in" if you have one. Your browser opens on lu-labs.ai. After the login the page says "Signed in" and the app picks up the session on its own. The account card then shows your plan and your credits; "View plans" opens the pricing page if you have none.

Step 2: Switch to Cloud

Click the Cloud switch in the header next to the model picker. It turns into "Switch to Cloud?"; click again within six seconds. The picker now lists the hosted models and the composer shows a "Cloud" chip. Your local models are freed from memory and come back when you switch to Local.

Step 3: Pick the Model

Open the model picker and scroll to the Uncensored group, marked Beta. Pick DeepSeek V4.1 Flash Uncensored. The desktop app reads the hosted list from the server, so it is there without an app update.

Next to it you find Abliterated Large Flash, the other model that arrived the same day. Pick that one instead if you need to attach images: the DeepSeek build is text only in LU Cloud.

Step 4: Chat

Type as usual. Two controls next to the message box matter:

Long conversations are no problem for the window, which holds one million tokens. Each turn still carries the history, so a very long chat costs more per message than a fresh one.

Step 5: Agent Mode

The model calls tools natively, so it can drive the agent.

  1. Open a new, empty chat and click the "Agent" toggle above the message box before the first message.
  2. In "Where should the agent work?", choose "Sandbox" for a first try, or "Pick a folder…" for a real project.
  3. Describe the task with the result you want, for example: "Search the web for the three latest reviews of this game, read them and write a summary to notes.md."
  4. Approve the tool calls as they come. You see which tool the model wants to call and with what.

The workspace protection is a folder jail, not a virtual machine: commands run on your computer. A model that does not refuse also does not hesitate, so read each tool request before you allow it.

Step 6: The Code Tab

  1. Open the Code tab and pick your project folder with "Select folder...".
  2. Leave the mode on "Ask permissions" at first: commands need your ok, and edits come as a diff before they land.
  3. Pick DeepSeek V4.1 Flash Uncensored and give a coding instruction, such as "Write a script that renames the photos in this folder by the date they were taken."
  4. Follow the plan bar, review each diff, then accept or reject it.

In the Browser

  1. Open lu-labs.ai and sign in with the same account.
  2. Open the Studio and the model picker. In the browser the group is called Unrestricted and the model DeepSeek V4.1 Flash Dealigned, after the team that made it.
  3. Chat, Agent and Code work there with the same credits.

On Your Phone

What It Costs

Credits per tokenPer million tokens
Inputabout 0.0225about 22,500
Output, thinking includedabout 0.09about 90,000

The meter follows the live list price, so the figures can move a little. A 15 EUR pack carries 450,000 credits. Current plan and pack prices are on the pricing page.

When It Does Not Work

Questions

Do I need a new version of LU?

No. Version 3.0.7 reads the hosted model list from the server, so the model appears in Cloud mode without an update.

Why does it have another name in the browser?

In the browser the group is called Unrestricted and the model DeepSeek V4.1 Flash Dealigned. It is the same model at the same price.

Does it work in Agent mode and the Code tab?

Yes. It calls tools natively, so both run on it.

How do I keep the cost down?

Switch Think off or set the effort to Low when a turn does not need reasoning, and start a fresh chat when the history has grown long.
