Given the current llm context size limitation, what is the state of art for feeding large doc/text blobs into llm for accurate processing?

The current generation of models all support pretty long context now - the Gemini family has had 1m tokens for over a year, GPT-4.1 is 1m, interestingly GPT-5 is back down to 400,000, Claude 4 is 200,000 but there's a mode of Claude Sonnet 4 that can do 1m as well.

The bigger question is how well they perform - there are needle-in-haystack benchmarks that test that, they're mostly scoring quite highly on those now.

https://cloud.google.com/blog/products/ai-machine-learning/t... talks about that for Gemini 1.5.

Here's a couple of relevant leaderboards: https://huggingface.co/spaces/RMT-team/babilong and https://longbench2.github.io/

		sorry I should have been more clear, I meant around open source llms. and I guess the question is, how are closed source llm doing it so well. And if OS OpenNote is the best we have...

Generally use 2.5 flash for this, works incredibly well. So many traditionally hard things can now we solved by stuffing it into a pretty cheap llm haha.

		What do you mean by “traditionally hard” in relation to a pdf? Most if not all of the docs I’m tasked with parsing are secured, flattened, and handwritten, which can cause any tool (traditional or ai) to require a confidence score and manual intervention. Also might be that i just get stuck with the edge cases 90% of the time.
