Run Flux locally, the short version

The simplest way to run Flux locally is the free Draw Things app, no code needed. It runs on a Mac or iPad only. You can download Flux.1 dev, Flux.1 schnell, and the newer Flux 2 (dev and the smaller Klein builds). Klein 4B finishes in about 40 seconds on Apple Silicon, while full-quality dev takes several minutes.

Need a quick and private way to create AI images without relying on pricey subscriptions? Check out Flux, a handy open-source text-to-image model that you can run right on your computer with the Draw Things app. Whether you’re an artist, a developer, or just having fun with AI, running Flux locally means you’re in control, and you don’t need an internet connection.

This guide will help you set everything up, even if your device isn’t super powerful. Don’t worry, there’s a way around that.

Best Tool to Run Flux Locally: Draw Things App

If you want to run Flux easily on your computer, the best option is the Draw Things app. In 2026 the best way to run Flux locally on a Mac is still Draw Things, a free one-click app that now also handles Flux 2. It’s a free tool made for generating images with AI right on your machine, so you get a Flux AI image generator local to your own device, with no cloud round-trip. With Draw Things, you get:

  • One-click downloads for models
  • The ability to generate images offline after you set it up
  • Control over steps, guidance scale, resolution, and other settings
  • Support for LoRAs, custom styles, and generating multiple images at once

Draw Things officially supports Flux, so you can install Flux on Mac with just a few clicks – no code or complicated setup needed. If your hardware isn’t cutting it, you can check out Rentamac.io for remote access to powerful Mac minis that can handle models like Flux without having to buy new equipment.

How to Run Flux AI Locally, Step-by-Step

To run Flux locally, you can:

1. Download and install Draw Things on your device.

2. Open the app and go to the model downloader section.

3. Download the selected Flux AI model from the list.

4. Load and run the model locally.

Draw Things lets you install Flux AI locally on a Mac in a few clicks, no code and no command line. Now let’s examine each of these steps carefully.

Step 1: Download Draw Things

Head over to the App Store and download Draw Things – it’s free and gets updates often.

Download Draw Things

If you don’t have a Mac or your computer isn’t powerful enough, you can rent a ready-to-go Mac mini from Rentamac.io. It’s a simple way to get Apple Silicon performance without any hassle. You can run Draw Things with Flux easily, without worrying about setup or buying new hardware.

Step 2: Open the App and Load the Flux Model

After installing, launch the Draw Things app. You’ll see the following interface, with three options:

Draw Things Interface

Choose the second option: Download a model via Draw Things. Then, look for “Flux” in the models section.

Choose Flux

You’ll find different versions of the Flux model. To install Flux AI model locally on your computer, pick a variant in the downloader and Draw Things sets everything up for you. The list now includes:

  • Flux-1-schnell
  • Flux-1-dev
  • FLUX.2 dev
  • FLUX.2 Klein (the smaller 4B and 9B sizes)

Draw Things added FLUX.2 support in its December 2025 update, so the newer Flux 2 models show up alongside the original Flux.1 ones. Choose your preferred variant and click Download.

This will automatically install the model and prepare it for local use.

Step 3: Adjust Settings (Optional)

You can adjust the settings to fit what you need or what your computer can handle:

Adjust Settings
  • Sampling Steps – Using a higher number of sampling steps gives you better details, but it takes longer. The Flux models usually work well with 1 to 150 steps.
  • Image Size – You can choose from different suggested measurements. For best results, we suggest using 1:1 / Normal size.
  • Strength – A high value of strength allows more artistic freedom from the original, ranging from 0% to 100%.

These tweaks can help you get the right mix of speed and quality. Feel free to experiment since there are no limits on usage.

Step 4: Start Creating Images

You’re all set to create! Just type what you want in the text box, like “Create an image of a guy drinking a cocktail,” and hit Generate.

Which Flux versions can you run locally?

So which Flux model should you actually download? You can run Flux.1 dev, Flux.1 schnell, and the newer Flux 2 (the dev build and the smaller Klein models) on your own Mac. You cannot run Flux.1 Pro locally, it is API-only and was never released for download. Draw Things downloads all of the local-friendly versions for you.

Here is how the variants break down:

  • Flux.1 schnell is the fastest and lightest on memory (Apache 2.0 license), so it is a good first download on a smaller machine.
  • Flux.1 dev gives higher-quality images with non-commercial weights, and it asks for more memory in return.
  • Flux 2 dev is the bigger, newer model, while Flux 2 Klein comes in two smaller sizes (4B and 9B) that fit tighter memory budgets.

Yes, you can run Flux 2 locally on a Mac. Draw Things added Flux 2 support in its December 2025 update, so both the dev build and the Klein sizes download the same way the older Flux.1 models do.

A quick reality check on the distilled models. Klein and the other smaller builds trade some image quality for speed, so text and fine details can come out wrong. When I ran the Klein 4B build for fast drafts, it was great for ideas but I switched to a heavier model whenever I needed the result to hold up.

One thing trips people up: Flux.1 Pro. If a guide tells you to download and run Pro on your own computer, it is wrong. Pro lives behind a paid API and there is no local file to install, so point yourself at dev or schnell instead.

If you only want to access Flux AI online, hosted web tools exist, but running it locally keeps your prompts private and removes usage limits. Everything in this guide is the local route, where you run Flux on Mac with the model files living on your own machine.

Real-World Cases to Use Flux

Flux is great for anyone who needs reliable image generation without relying on complicated external tools. Here are some great ways to use it:

  • Concept Art – Quickly whip up characters, backgrounds, and scenes for games, books, or personal projects.
  • Design – Create drafts or inspiration for posters, branding, social media, or digital art.
  • Creative Brainstorming – Turn text prompts into visuals in no time, which is perfect for early product or content ideas.
  • Educational Use – Teachers and students can learn about AI art concepts and prompt crafting without needing the internet.
  • Model Testing – Use Draw Things to experiment with different styles, samplers, and image sizes right on your device.
  • Remote Teams – Work on visuals together without sharing files on third-party servers, especially useful for confidential projects.

Minimum Hardware Requirements for Running Flux

If you want to run Flux smoothly with the Draw Things app, here’s what you’ll need:

ComponentWhat you need
ProcessorA modern multi-core CPU. Apple Silicon (M1 through M4) is best; recent Intel Macs work but run slower.
Memory (RAM)At least 8 GB for small models; 16 to 32 GB for faster generation and higher resolution.
StorageAt least 10 GB free for the Flux model files; more if you keep several models or LoRA extensions.
Operating systemmacOS 12.4 or newer (also iOS 15.4 or newer, iPadOS, and visionOS). No Windows, Linux, or Android version.
GraphicsNo external GPU needed. Flux works well with Apple’s Neural Engine or the integrated GPU.

How much RAM do you need per Flux version?

On a Mac there is no separate VRAM. The model shares your unified memory, so the number that matters is total RAM. How much you need depends on which Flux version you pick and how heavily it is quantized.

Quantization is just a smaller, compressed copy of the model. It fits in less memory and runs faster, at a small cost to image quality. A Q4 (GGUF) build is much lighter than the full FP16 one. Most VRAM advice online is written for NVIDIA cards, but on Apple Silicon that all maps to your total Mac RAM.

Flux versionLightest buildRAM to keep freeNotes
Flux.1 schnellGGUF Q4About 8 to 12 GBFastest, lowest memory of the v1 line
Flux.1 devFP8 / Q8About 16 GB (24 GB at full FP16)Heaviest of the v1 line, best quality
Flux 2 Klein 4B4-bitAbout 20 GB observedDistilled, fast drafts
Flux 2 dev4-bit / GGUFAbout 18 to 24 GBLargest, plan extra disk space
RAM needed on a Mac per Flux version, with the lightest quantized build of each.

The 8 GB minimum and 16 to 32 GB recommended numbers from above still hold, just tie them to a variant. Schnell at 8 GB is realistic, dev wants 16 GB or more, and the Flux 2 models are happier with 20 GB plus.

On our own 16 GB Mac mini M4 instances, schnell and a quantized Flux.1 dev run fine, but Flux 2 Klein is where 16 GB starts to feel tight. If your machine sits below those bands, a rented Stable Diffusion on Mac box gives you the same Apple Silicon memory without an upgrade.

Frequently asked questions

Do I need a Mac to run Flux locally?

Flux runs best with the Draw Things app, which is designed for macOS. If you don’t have a Mac, you might want to rent one from Rentamac.io to get started fast.

Is Draw Things free?

Yes, Draw Things is free on the Mac App Store. There are no subscriptions and no usage limits, and updates are free too, so the only cost of running Flux is the disk space the model files take up.

Can I use Flux without internet?

Yes! Once you download the model in Draw Things, you can use Flux offline.

What kind of prompts can I use?

Any descriptive text works well. Try phrases like “vintage car in desert at sunset” or “futuristic city in rain” for detailed images.

How long does it take to generate an image?

It depends on the model and your chip. A small distilled model (FLUX.2 Klein 4B at 4 steps) finishes in about 40 seconds on Apple Silicon. A full-quality model like FLUX.1 dev or FLUX.2 dev takes several minutes per image on a MacBook (one creator measured about 7 minutes for FLUX.1 dev). “A few seconds” only holds for the smallest, most-quantized models.
