this seems to be similar to gpt-pro, they just have a very large attention window (which is why it's so expensive to run) true attention window of most models is 8096 tokens.

What's the "attention window"? Are you alleging these frontier models use something like SWA? Seems highly unlikely.
well the attention is a matrix at the end of a day which scales exponentially, 1m tokens would need more memory than any computer system in the world can hold. They maybe have larger ones such as 16k to 32k, but you can just see how GLM models work for more information.
Deepseek is the frontrunner in this technology afaik.
source on the 8096 tokens number? i'm vaguely aware that some previous models attended more to the beginning and end of conversations which doesn't seem to fit a simple contiguous "attention window" within the greater context but would love to know more
well 8096 is just the first number that came to my mind, obviously frontier models have 32k or above, but they essentially they have a layer which "looks" at a limited view of the entire context window. {[1m x 3-4 weights] attention layer to determine what is actually important} -> {all other layers}
