Cool idea. I keep looking for a search/filter/facet function to leverage the tagging and classification they've done with the models, but I can't find one.
Thanks! This is definitely a feature we want to add in the future.

#12A lot of these models are open source, I wonder who would this product market towards?
Can I ask where one can download the pretrained weights? Is there some online repository?
Some for YOLOv4 https://github.com/AllanYiin/YoloV4

#13Weird, the account registration wouldn't work on my normal IP, claiming 'too many requests' Worked fine on a VPN however (sorry, I know you probably don't like this). After the account registration though, I did quite like trying out a couple models out on a couple frames of footage to see if the models would "work".
Thanks for the report- it looks like we had our anti-spam set a little too sensitive. Glad you like the site!

#14If this becomes something like huggingface for Computer Vision - awesome.
For now, it's a shame model descriptions seem to often be lifted straight from README.
Having a more standardized description, something like model cards [1] (CV example [2]) would be hugely beneficial IMO.

It's a good suggestion, thanks.

#16How do you stop piracy on something like this?
Surely I could take a model, refine it slightly to get distinct weights (ie. not a flat clone) and unload it as my own novel variant?
...and I mean, is the problem not utterly fundamental?
When is a model “yours” or sell?
When you trained it? When you’re not using transfer learning? When you wrote the paper? When you own the training data? When you can recreate it from scratch?
I see this being problematic to look after...

The value of these could be in private datasets. Model architectures are not really patentable and ownership of a trained model has always been very muddy water.
That being said, if I am selling a bird classifier chances are that to train it I had to combine multiple datasets and someone can't easily finetune it to get better results.

You can look up the torchvision model zoo for pretrained weights of most popular architectures.
Tensorflow as an equivalent tool but I can't remember the name.

They dont need to fine tune it for better results, they only need to fine tune it to give different results and sell it for $5 less than you are.

#20I don't think this will be a successful business model. Niche AI models cost a lot of money to gather the right dataset and train, but they would probably only sell to <100 companies/individuals. So pricing a model at $50-100 isn't profitable. If you're selling general CV models, you have to compete with the plethora of open source ones, including ones that Google and Facebook release for free, which are trained on huge datasets and using a lot of compute resources.
