A few updates to share with you today We're experimenting with fast models in the interface on alpha.midjourney.com .
The Styles sidebar can now preview what your latest prompt looks like across styles.
Turn on "Live previews" and see a preview of your prompt using liked and featured styles.
Click on the thumbnail to generate with that style.
We've also improved inpainting and outpainting with the edit model.
Making targeted edits to the image will change only the pixels that you've selected.
This gives you more control, and allows you to make repeated edits without degrading the quality of the image.
Here's a bit more info about how you can use the edit model.
We've also made tile --tile work better for V8.1/8.2.
Previously, you might have seen seams between your tiled images.
Now, they blend invisibly from one tile to the next.
We hope you have fun!
