Version 1.25 Latest version

Upscale images with SeedVR2

  • Added Upscale, a new mode next to Create and Edit. Add an image, choose an output size, and SeedVR2 3B enlarges it up to 4096 pixels on the long edge while restoring fine detail. No prompt is needed, and upscaling is included free.
  • SeedVR2 3B is a separate download of about 7.3 GB in Model Manager and needs at least 16 GB of unified memory. Macs with 16 GB can upscale up to 3072 pixels; 4096 pixels needs 24 GB or more.
  • Softness blurs the image a little before upscaling. Higher values help with small, noisy, or compressed images.
  • Choose Upscale image in the Gallery or the image viewer to open a picture in Upscale.
  • With PRO, the new SeedVR2 Upscale node adds upscaling to Studio workflows, with size and softness settings. The new Generate and Upscale sample creates an image with FLUX.2 Klein, upscales it, and saves it.
  • The Before / After view now fills most of the window. Zoom to 100%, drag the divider or move it with the arrow keys, or show both images side by side.
  • Zooming large images on the canvas uses less memory and no longer lags. When you drag, the image stays under the pointer.
  • Create, Edit, and Upscale now sit side by side, with a short line that explains the selected mode.
Version 1.24

More Ming image shapes and Krea 2 Fast mode fix

  • Ming-Image-0.1-Design now works with every image shape and size in Create, up to 2048 × 2048. Portrait and landscape shapes require PRO.
  • Ming now shows a preview while an image is being generated. Preview colors are approximate.
  • Fast mode for Krea 2 was missing in 1.23 and is available again.
  • ML Enhance is more reliable. After enhancing an image in Gallery or Studio, Create no longer asks you to download a model you already have. If the download fails, the app shows the reason and lets you try again.
  • When a prompt uses [option|option] choices, compared models now get the same text for each variation, so their results are easier to compare.
  • In Edit, the empty canvas explains what to do next. When you cannot generate yet, it says why and offers a button to show the settings. Seeds outside the allowed range are caught before generation.
  • The optional watermark now also shows the image size.
Version 1.23

Ming Fast mode and clearer Create controls

  • Ming-Image-0.1-Design now supports Fast mode with PRO, which generates images in 8 steps.
  • Microsoft Lens Turbo reuses prompt processing when you generate again with the same prompt.
  • LoRAs moved out of Advanced into their own section in the Create sidebar, which shows how many LoRAs are active.
  • The zoom control has buttons to zoom in, zoom out, fit the image, and show it at actual size. It stays hidden until you move the pointer over the image or change the zoom.
  • The image format section shows the selected shape and size, with an easier resolution menu. Shapes that need PRO show a lock.
  • The optional watermark shows generation time to one decimal place and notes when Fast mode was on.
Version 1.22

Ming images and a redesigned creation workspace

  • Added Ming-Image-0.1-Design in 4-bit and 8-bit precision for designs, text, and transparent backgrounds in Create and Studio. Downloads are about 13.4 GB and 25.1 GB; both need at least 16 GB of unified memory.
  • Ming supports square 1024 × 1024 and 2048 × 2048 output. On Macs below 24 GB, a 2048 request is generated at 1024 and resized. Ming does not support reference editing or custom adapters.
  • The redesigned sidebar has separate Create and Edit tabs that keep their own drafts. Image formats are easier to reach, with extra controls grouped under Options and Advanced. Paste, replace, or reorder reference images in Edit.
  • Each model remembers its image format and generation settings. Reset a model’s settings when needed, with an option to undo the reset.
  • Search the model picker and Model Manager by name, precision, or editing support. Filter installed models and find choices compatible with your reference images.
  • Start an edit or reuse settings from a Gallery image. The app explains which settings were restored and what is missing. PNG export with PRO is also available from the image menu.
  • Select a queued image to review the prompt and settings submitted for that job.
  • FLUX.2 Klein now supports portrait and landscape formats with PRO, as well as square images.
  • Reduced repeated work and memory use during Krea 2 generation. Fixed INT4 ConvRot Fast mode failing after switching from Quality on supported M5 Macs.
  • Qwen Image Edit 2511 can reuse prompt processing when the prompt and reference images match a previous request.
  • The optional watermark is now under Settings > General and remains off by default. It includes the model, precision, generation time, app name, and device.
Version 1.21

Fast and Draft generation fix

  • Fixed a problem that could stop Fast or Draft generation after switching from Quality on supported M5 Macs.
  • Generated images no longer include the Radiant Canvas watermark by default. Turn on the watermark option when you want to add it.
Version 1.20

Dynamic memory handling and easier model downloads

  • Generation now watches available memory, releases unused model memory when needed, and warns you before a low-memory failure. If memory stays critically low, generation stops safely and explains what to change.
  • The model picker shows estimated free memory so you can see when your Mac is under pressure.
  • Model downloads can use another source when the main source is unavailable.
  • Review prompts have improved timing and window handling, and Help includes an option to write a review.
  • Added a What’s New window after updates. Reopen it from Help > What’s New.
Version 1.19

Smoother Studio editing and macOS 27 support

  • Studio number and color fields now apply valid changes as you type, so connected steps stay up to date.
  • Invalid Studio values now show a compact warning without covering nearby controls.
  • Selecting text inside a Studio node no longer moves the canvas.
  • Added compatibility updates for macOS 27.
  • Added a clearer message when the App Store cannot open the purchase window.
Version 1.18

Random prompt choices and larger batches

  • Use random choices in Simple prompts, such as "a [red|blue] ball above a [lake|desert]". Each image picks one option from each group. Your template stays in the editor and prompt history, while image details show the chosen text.
  • Create up to 100 variations at a time and keep up to 100 images in the generation queue. Type the variation count directly or use the stepper. Image editing still creates one result at a time.
  • Qwen Image Edit now uses Lightning V2. Existing installations need an update download of about 850 MB per precision option, or about 1.7 GB for both. The app asks before downloading and keeps your selected model.
  • Fixed delays and missed cancellation requests when stopping generation or switching models.
  • Reduced lag when scrolling through the Gallery and loading thumbnails.
  • The before-and-after image editing comparison now shows the prompt used for the edit.
Version 1.17

Image editing and more model choices

  • Add a reference image and describe what you want to change with FLUX.2 Klein. Qwen Image Edit 2511 is also available, with support for up to three reference images.
  • Use image editing in Simple, or add an Image Edit step to a Studio workflow with PRO.
  • Added higher-precision options for Z-Image, FLUX.2 Klein, ERNIE-Image, and Qwen Image Edit for Macs with more memory. These use larger downloads and may be slower; differences in the results can be subtle.
  • Models are now grouped by family, with standard and higher-precision choices and clearer memory guidance.
  • Fixed an issue that could prevent the smaller Krea 2 INT4 ConvRot model from generating images.
  • Saved and exported images now use readable filenames that include when they were created. Saved Studio workflow filenames use the workflow title.
  • Fixed slow previews when comparing models, and improved dragging and moving around the Studio canvas.
  • The PRO free trial is easier to find.
Version 1.16

Smoother Studio and easier Gallery selection

  • Moving around the Studio canvas and working with connections feels smoother.
  • Select several Gallery images with Command-click or Shift-click, move between them with the arrow keys, and press Space to preview. Favorite or trash selected images together.
  • Fixed Studio previews replacing the finished image in Simple when switching between workspaces.
  • Studio now follows your selected generation settings more reliably.
Version 1.15

More reliable Studio workflows

  • Fixed workflows using an original image when they should use the cropped, edited, or processed result from a connected step.
  • Cropping now matches the area you select, and the mask editor remembers your edge settings.
  • Image grids, comparisons, batches, and exports now use the intended images and order more consistently.
  • Review an enhanced prompt before applying it. Changing the source prompt clears the old enhancement.
  • Added clearer help and input checks for Studio controls.
Version 1.14

Build and save workflows in Studio

  • Studio adds a visual workspace where you connect prompts, models, and image steps into a workflow you can save and use again.
  • Preview results and compare variations while keeping the steps that made them together.
  • Basic text-to-image workflows are free. PRO adds advanced image processing, masks, batches, and export steps.
  • Added a clearer notice when image generation runs out of memory.
Version 1.13

Help with prompts and lower memory use

  • Prompt enhancement can expand a short idea into a more detailed image description on your Mac.
  • Reduced memory use for the smaller Krea 2 model and improved generation on M1 Macs with 16 GB of memory.
  • Improved model downloads and made small fixes to the creation controls and Gallery.
Version 1.12

Compare models and create more variations

  • Try the same prompt with several models and generate multiple variations in one go.
  • Queue more images while a generation is running, and remove queued items you no longer need.
  • Added Microsoft Lens Turbo as another model option.
  • Refreshed the creation workspace and improved live previews, progress updates, and Gallery browsing.
  • Fixed a generation slowdown and reduced interface lag while images are being made.
Version 1.10

A new name and more models

  • Krealize is now Radiant Canvas.
  • Added Krea 2 Q8, Z-Image, FLUX.2 Klein, and ERNIE-Image model options.
  • Added more control over generation settings.
  • Improved model download speed, reduced memory use, and fixed issues in Demo Mode.
Version 1.9

More reliable model downloads

  • Improved checks for downloaded model files so incomplete downloads are caught before generation.
  • Model downloads can reuse valid files already on your Mac instead of downloading them again.
