Yes, it's hard to know in the balance whether the net contribution of these advertising companies (fb and google mainly) is a net positive, but their contribution to ML research is unmatched and has created an insane amount of value (I'd speculate rivaling their market caps but someone can probably prove me wrong) in business and research that uses the tools they've built.
The net impact of these companies is massively positive. Facebook, with its trust-engendering social graph, enables huge numbers of businesses and social groups to exist that otherwise couldn't while Google has enabled so much information discovery that we just take for granted now.
Of course I would argue there's a better way to provide these kinds of services that concentrates power less, and that's decentralization with cryptoeconomic incentives to maintain consensus, but for their generation, they did well.
AITemplate delivers much better perf (1.9x ~ 12.8x) compared to PyTorch eager on SOTA models, including Bert, ResNet, VIT and StableDiffusion.
AITemplate also delivers high perf numbers using AMD GPUs (MI-250). With AITemplate, MI-250 achieves 80% ~ 96% A100 perf on various ResNet / Bert / VIT models.
AITemplate uses sophisticated fusion techniques to optimize perf, including vertical, horizontal, and memory fusions.
btw, I'm one of the authors of AITemplate, happy to answer any questions.
Thanks, that is very helpful. Do you have to train the model differently for use with AITemplate? Could it be helpful for Leela Chess Zero (LC0)? I think LC0 has a generic Pytorch backend, that is several times slower than its NVidia specific CUDA backend. I'm not very clueful about this stuff though.
As @haolu7 mentioned, you could take a pre-trained model and use AITemplate to do model inference. All you need to do is to re-write the model using AITemplate frontend and map PyTorch params to AITemplate params. Besides, AITemplate has a limited operator coverage compared to mature frameworks like PyTorch so you may need to implement your own kernels if necessary (though it already supports Bert, VIT, StableDiffusion, ResNet, Detectron, and general recommendation models).
How does the performance compare with tensor rt? I didn't see any benchmarks comparing against that. I expect it to be lower for now, but excited for see what the future brings.
AITemplate-PyTorch Stable Diffusion is the fastest stable diffusion inference solution by pushing image generation below one second on A100 (batch 1: 0.7s / 25 steps, 1.3s / 50 steps; batch 3: 1.6s / 25 steps, per image 0.55s; batch 16 7.9s / 25 steps, per image 0.49s) for the first time, 2.57X faster than Keras' XLA-based GPU compilation solution.
Can you please eloborate, how many milliseconds does it take to generate 1 image with these wonderful improvements? I will be very grateful for your answer! Thank you very much!
Or if you count in another way. In one second, how many pictures it will be able to generate, with these parameters. It could be 1.05, 1.1, or say 1.5 or even 2 pictures. Thank you very much for your post! I will be very grateful for the answer!
One more question, if you don't mind. 1 image is generated in 0.7 seconds (25 steps ) and the same single image with 50 steps will be generated in 1.3 seconds. So it's much cheaper to generate more images for the same promt. Am I right or am I missing something ? Thanks in advance for your answer.
P.S.
Though it should be 1.4 seconds. 0.7*2=14.If you think twice the speps, twice the time.

[ 3.0 ms ] story [ 89.0 ms ] threadMaybe this is to attract better engineers but all in all this has been a net postive for software development. So credit where it is due.

Meta is open sourcing AITemplate, an inference engine for both Nvidia and AMD GPUs. Code: https://github.com/facebookincubator/AITemplate.

We don't have an official comparison between AITemplate and tvm / onnx for now, but we do have perf numbers like https://github.com/facebookincubator/AITemplate/tree/main/ex..., https://github.com/facebookincubator/AITemplate/tree/main/ex.... Feel free to run these examples on other frameworks and compare perf.
More benchmark numbers and repro at: https://github.com/facebookincubator/AITemplate/tree/main/ex...
One or two more optimizations and we're gonna have live-update results.
Thank you so much for your post! I would be very grateful for the response!

Would AITemplate be able to run with those constraints?
