Apparently there was already a discussion of this talk here after it was given live. But I missed it. So now will do: I do care about potential AI harms, but disagree with pretty much everything he says here! will elaborate in the response.

Markovian Thinking by @Mila_Quebec & @Microsoft lets LLMs reason with a fixed-size state โ€“ compute stays the same no matter how long the reasoning chain gets. This makes RL linear-cost and memory-constant. The teamโ€™s Delethink RL setup trains models to be Markovian Thinkers,

Thanks for sharing, @TheTuringPost We propose Markovian Thinking as a new paradigm, and Delethink as a simple, concrete instantiation enabling constant-memory, linear-compute reasoning that keeps improving beyond training limits.

Nice paper! Make the context for reasoning local and train an RL model with such truncation. This way the model "markovinifies" and makes use of its context efficiently!

Itโ€™s clear next-gen reasoning LLMs will run for millions of tokens. RL at 1M needs ~100ร— compute than 128K. Our Markovian Thinking keeps compute scaling linear instead. Check out Miladโ€™s thread; some of my perspectives below:

Long reasoning without the quadratic tax: The Markovian Thinker makes LLMs reason in chunks with a bounded state โ†’ linear compute, constant memory and it keeps scaling beyond the training limit. 1/6

I moved out of my home in 2008 and I still call my mom every day! If you read this and you donโ€™t call your parents everyday, call them NOW! The love parents have for their kids is priceless! I realized it only after I became a father myself!

Story time: After I moved out of my home in 2014 to live in Japan, initially I used to call my parents daily. But as I became more "internationalized" I started calling my parents less and less. I used to tell my mom "I have nothing to talk about so we don't need to call daily".

@karenvaites Honestly, my takeaway from this isn't that tracking is bad, it's that teachers can't be trusted to do it right. Which, functionally, might be the same thing.
