<p>Was Alphago's move 37 original?<p>In the last step of training LLMs, reinforcement learning from verified rewards, LLMs are trained to maximize the probability of solving problems using their own output, depending on a reward signal akin to winning in Go. It's not just imitating human written text.<p>Fwiw, I agree that world models and some kind of learning from interacting with physical reality, rather than massive amounts of digitized gym environments is likely necessary for a breakthrough for AGI.</p>

<p>Location: SF (current).  NYC/Philly general area acceptable.  Remote okay.
email: rrenaud@gmail.com
Resume:  16 year SWE -> MLE @ Google, MS from NYU with focus on ML.  Retired.  Now I hack on data analysis for video game projects for fun, and I love it.  I'd take crazy low compensation to do work with interesting game data sets.  EG, for game balance, strategic analysis, or to improve/augment game video content.</p>

<p>What do y'all think about the latency/quality tradeoff with LLMs?<p>Human voices don't take 30 seconds to think, retrieve, research, and summarize a high quality answer. Humans are calibrated in their knowledge, they know what they understand and what they don't.  They can converse in real time without bullshitting.<p>Frontier real time-ish LLM generated voice systems are still plagued by 2024 era LLM nonsense, like the inability to count Rs in strawberry. [1]<p>I'd personally love a voice interface that, constrained by the technology of today, takes the latency hit to deliver quality.<p>[1] <a href="https://www.instagram.com/reel/DTYBpa7AHSJ/?igsh=MzRlODBiNWFlZA==" rel="nofollow">https://www.instagram.com/reel/DTYBpa7AHSJ/?igsh=MzRlODBiNWF...</a></p>

<p>The Google style guide for C++/Java/Python are opinionated, hard fought, wise, and they elimate a large source of errors while minimizing harmful, unneded inconsistences.  They picked a style that made great realistic use of the best cognition at the time.<p>The intent is still great, but now we should think about writing good general rules for building programs that are essentially all AI generated.  What generic wisdom leads to flexible, auditable, composable and robust apps and systems?</p>

<p>Please serve well quantized models.<p>If you can get 99 percent of the quality for 50 percent of the cost, that is most times a good tradeoff.</p>

<p>Cite a source.  Your concrete claim is that, on average, for every $1 of subscription revenue on a monthly subscription, OpenAI and Anthropic were losing $11.50?<p>It seems completely implausible.<p>I could believe that if a $20 sub used every possible token granted, it would cost $250.  But certainly almost no one was completely milking their subscription.  In the same way that no one is streaming netflix literally 24/7.</p>

<p>I used to play very competitively, but I've been more chill recently.  I just think it's a nice problem/dataset to work with, because of the depth of my understanding of the game.</p>

<p>I’ve been experimenting with a live win probability predictor for the 10-player arcade game Killer Queen. The goal is to predict the winner in a causal, event-by-event fashion.<p>Right now I’m struggling to beat a baseline LightGBM model trained on hand-engineered expert features. My attempts at using a win probability head on top of nanoGPT, treating events as tokens, have been significantly worse. I am seeing about 65% accuracy compared to the LightGBM’s 70%. That 5% gap is huge given how stochastic the early game is, and the Transformer is easily 4 OOM more expensive to train.<p>To bridge the gap, I’m moving to a hybrid approach. I’m feeding those expert features back in as additional tokens or auxiliary loss heads, and I am using the LightGBM model as a teacher for knowledge distillation to provide smoother gradients.<p>The main priority here is personalized post-game feedback. By tracking sharp swings in win probability, or $\Delta WP$, you can automatically generate high or low-light reels right after a match. It helps players see the exact moment a play was either effective or catastrophic.<p>There is also a clear application for automated content creation. You can use $\Delta WP$ as a heuristic to identify the actual turning points of a match for YouTube summaries without needing to manually scrub through hours of Twitch footage.</p>

<p>A compiler that can turn cash into improved code without round tripping a human is very cool though. As those steps can get longer and succeed more often in more difficult circumstances, what it means to be a software engineer changes a lot.</p>

<p>Previously, I made a live win probability model for the 5v5 arcade game Killer Queen Arcade from their game events API.<p>Now I am trying to use that model to make:<p>1.  A post game instant replay that shows the most important/pivotal moments from the most recently finished game.  Some arcades have a seperate display for observers, it could work well there, or as good filler between matches on twitch streams.<p>2.  A personalized per tournament/yearly highlights recap.<p>If it works well, it might be a kind of tool that generalizes well for summarizing long twitch streams for Youtube.<p><a href="https://github.com/rrenaud/kq_stream_highlights" rel="nofollow">https://github.com/rrenaud/kq_stream_highlights</a></p>
