ChatGPT didn't begin 18 months ago, the research that it originates from has been ongoing for years, how old is alexnet?
I'm referencing ChatGPT's initial benchmarks to its capabilities to today. Observable improvements have been made in less than two years. Even if you just want to track time from the development of modern LLM transformers (All You Need is Attention/BERT), it's still a short history with major gains (alexnet isn't really meaningfully related). These haven't been incremental changes on a slow and steady march to AI sometime in the scifi scale future.
AlexNet is related, it was the first use of consumer gpus to train neutral networks no?
No, not even remotely. And that's kind of like citing "the first program to run on a CPU" as the start of development for any new algorithm.
As far as I can find out, there was only one use of GPUs prior to alexnet for CNN, and it certainty didn't have the impact alexnet had. Besides, running this stuff on GPUs not CPUs is a relevant technological breakthrough, imagine how slow chayGPT would be running on a CPU. And it's not at all as obvious as it seems, most weather forecasts still run on CPU clusters despite them being obvious targets for GPUs.
What? Alexnet wasn't a breakthrough in that it used GPUs, it was a breakthrough for its depth and performance on image recognition benchmarks.
We knew GPUs could speed up neural networks in 2004. And I'm not sure that was even the first.
Okay, so some of the advances that chatGPT uses (consumer GPUs for training) are even older? 😁
Why stop there? The digital computer was introduced in 1942 and methods for solving linear equations were developed in the 1600s.
