Yeah, you could try that. The limit for compressed/random data is roughly 2.6MB. In my experience, sending smaller images (file size) has resulted in a significant improvement in latency.

These are still gigantic image sizes for LLMs, it should be possible to downscale them to ~100-300kb size and get similar results.

fry69•10/30/24, 5:15 PM

Most likely the AI API will scale those images down anyway before processing.

JPEG would work well. Keep in mind that LLMs actually use very small sizes internally anyway - a size of 640 pixels is good enough, no need for 4k images.

With the object classification from fb i feel like if you resize the box dimensions dont work anymore

Raylight

R

Raylight•10/30/24, 5:39 PM

Either way will work. Compressing or downscaling. The main thing is to get the file size down. When I tested I could shave of half a second of latency simply by sending the (1024x1024) image as a ~200kb jpg instead of a 2MB png.

The box dimensions should be based on the pixels you give, so it should be consistent?

Isaac McFadyen•10/30/24, 5:39 PM

I'd recommend resizing over compressing. A compressed 4k image is still going to be resized internally by the model anyway, and by aggressively compressing big images you're going to lose some of the details.

Martijn

MMartijn Yeah but if I want to then visualize the boxes on the original image it wouldnt ...

Isaac McFadyen

I

Isaac McFadyen•10/30/24, 5:40 PM

Just make sure to calculate the resize ratio.

Martijn

M

MartijnOP•10/30/24, 5:40 PM

I guess yeah

Isaac McFadyen

I

Isaac McFadyen•10/30/24, 5:40 PM

If you have an image that is 3840 and resize to 640 then just multiple the returned coordinates by 6 (3840 divided by 640)

Isaac McFadyen

I

Isaac McFadyen•10/30/24, 5:41 PM

Just an FYI that I'm not picking 640 pixels arbitrarily - that's the actual size used by lots of models (ex. YOLO object detection)

Martijn

M

MartijnOP•10/30/24, 5:42 PM

Kind of difficult since the images I want to classify are user input and could differ but I’m sure ill figure it out

Isaac McFadyen

I

Isaac McFadyen•10/30/24, 5:43 PM

Hmmm yeah. So depending on what your input pipeline looks like, I'd take the longest dimension (height or width) and then divide that by 640, and then resize to 640, send the image, and multiple all results by that ratio

Isaac McFadyen

I

Isaac McFadyen•10/30/24, 5:43 PM

Might be tricky if your pipeline is browser based but there's still options even then

Martijn

M

MartijnOP•10/30/24, 5:44 PM

Users upload through an app, it gets stored in R2 and then i’ll likely run some automation on it for it to be classified

Isaac McFadyen

I

Isaac McFadyen•10/30/24, 5:44 PM

If you're using a Worker for that automation you can try sharpsharp, I believe they have a WASM backend now that might work in Workers

Martijn

Raylight•10/30/24, 6:04 PM

Jpeg blocks are 8x8 pixels, so you're unlikely to lose details if the image is resized by a large factor. I believe resnet expects 224x224 as input, which would amount to ~150kb of uncompressed image data. If you're going to handle the resizing yourself you still have to decide on which kernel to use and in which color space to do the operation - e.g. lancoz, linear gamma. Worst case scenario is if you happen to resize to image dimensions that doesn't quite match the model, since the low res image will be resized once more. So idk, I'd probably go with lossy compression. Although if the image dimensions are huge, it could make sense to bring them down a bit.

A lot of prompts triggers the NSFW error. "cyber", "bar", "toe", "arm", "nose", "drill", "boot", "spy", "cow", "chicken" just from trying a few random one word prompts. "a cyberpunk cat" is ok, "cyberpunk cat" isn't.

This. Although I wish https://developers.cloudflare.com/workers-ai/privacy/ were more clear. It feels well-intended and as if it is written to provide peace of mind, but "Cloudflare does not use .. to" can be read as "does use, except for these two things" in the same way that "may be stored by Cloudflare if you specifically use a storage service" can be read as "does not store, except if".

Raylight

Raylight•11/1/24, 10:30 AM

Right now, however, I'm more concerned about Cloudflare throwing NSFW errors and wonder if this filter is Cloudflare's own doing, because if so then IMO Cloudflare is on a slippery slope of engaging in content moderation, and I can't find anything about NFSW in terms and conditions. So I would very much like to have some clarity regarding this. Might be raising an "unpopular option" thing here, but well.. I feel it is important.
