This is cool and looks like a great way to drain my phone battery :)

I just used the prompt "A person looking at their phone in amazement" and got a good picture.

Beware that on startup the app downloads almost 2 gig of data.

It would be awesome if it just quickly took a picture from the front camera for that particular request and then just filter it to finish the "in the style of andy warhol"

I have generated some images, I think it only takes less than 1% of the battery for an image, this is already much better than most of the game(for having fun).

It took my battery from 80 to 77% for one generation on the default settings (384^2, 30 iterations). Less than a minute of compute time to complete a generation.

Iphone battery health reports a battery at 100% health. This is an iphone SE3.

Amazing how huge the difference in energy consumption is for the system in standby vs going full throttle.

EDIT: I generated 3 more images; every subsequent generation reduced battery capacity by another 2%. My phone doesn't seem to heat up at all, interestingly.

My iPhone 12 mini dropped from 76% to 71% and got noticeably warmer. Battery health is way worse than yours, 85%.

I wonder if generating a picture uses so much juice that it even drops the percentage while charging...

EDIT: Generating a picture while charging did not drop the percentage.

I generated a bunch of pictures while charging and the percentage still went up (albeit slowly).

Late to the party but depending on your charger voltage, it may be. e.g. I can charge my mbp on a cheap usb-usb-c charger but as soon as I use it _too_ much, it will stall, or worse, lower.

It does warn you on startup about the download if you're not on wifi.

Good time to try 5G ultra capacity if you have it on an unlimited plan - will be faster than most people's wifi.

Pivot alert

I reached 3Gbps over Verizon 5G in San Antonio last year and this year i get about 4Mbps over Verizon 5G in Ohio. It’s so bad I disabled it. I did read an article that iPhone 12 (which is what I have) have some kind of radio issue with 5G. Can anyone in here confirm?

Verizon has been real wonky all over Austin. If there's more than a handful of people in the area, bandwidth just goes to the crapper. I'll go from a couple hundred mbps on a good day with no clouds/wind/holding my phone just perfectly right in the right space, but usually get less than 1mbps on their 5g UW.

Yeah, its really bad. I keep having to disable 5G.

(I have not downloaded it.)

Q: How long does a run typically take? 60 seconds?

From the link:

> It took a minute to summon the picture on the latest and greatest iPhone 14 Pro, uses about 2GiB in-app memory, and requires you to download about 2GiB data to get started. Even though the app itself is rock solid, given these requirements, I would probably call it barely usable.

also

> Even if it took a minute to paint one image, now my Camera Roll is filled with drawings from this app. It is an addictive endeavor. More than that, I am getting better at it. If the face is cropped, now I know how to use the inpainting model to fill it in. If the inpainting model doesn’t do its job, you can always use a paint brush to paint it over and do an image-to-image generation again focused in that area.

Seems very worth a try. I'm downloading the model right now, it's going a bit slow, ~2MB/s.
