    “Base64Bench: How good are LLMs at base64, and why care about it?” by richbc

    This was a quick, short side-project produced during the MATS Research 8.1 extension. It's related to my group's main thread of work on black-box scheming monitoring through the connections to monitoring I explore below, but was time-boxed and pursued independently because I thought it was interesting! Executive Summary Figure 1. Accuracy vs. similarity threshold (0.95+) across 1700 pairs of encoding/decoding examples across a variety of datatypes and lengths. The accuracy is the proportion of the 3400 examples each model translated successfully (directly, with no reasoning or tools). Success for each task is defined by the normalised Levenshtein similarity of the answer/target pair hitting a given threshold, with a scoring requirement that model-encoded strings are decodable. Legend ordered by accuracy@1.0. Introducing Base64Bench: a simple new benchmark for evaluating models on their ability to encode and decode base64. Base64 encoding and decoding are reasonably complex computational tasks to do perfectly [...] --- Outline: (00:31) Executive Summary (03:07) An accidental (and surprising) discovery (08:03) Have LLMs actually learned the algorithm?

    “Maybe social media algorithms don’t suck” by Algon

    1 Insulting My Readers People keep complaining about how their twitter feed is infested with politics or relationship discourse, how Youtube keeps showing them Anime Girl Butts: A 5 Hour Review, or Facebook serves them up AI generated slop that clueless old-people upvote. They bemoan the tyranny of the Algorithm and talk about how social media companies are Out To Get You. That said Algorithm is fiendishly clever. That said Algorithm only cares about what grabs your attention, not what you want. That said Algorithm sucks. To which I say: Maybe you suck. Have you ever thought about that, eh, Lesswrong? No, seriously, consider it. Maybe this is just a skill issue? Maybe you've put your locus of control into FAANG's hands and are wondering where things went wrong? Maybe you don't know how to interface with algorithms? Maybe you don't focus on what you want to see more [...] --- Outline: (00:10) 1. Insulting My Readers (02:06) 2.

    “Sora and The Big Bright Screen Slop Machine” by Zvi

    OpenAI gave us two very different Sora releases. Here is the official announcement. The part where they gave us a new and improved video generator? Great, love it. The part where they gave us a new social network dedicated purely to short form AI videos? Not great, Bob. Don’t be evil. OpenAI is claiming they are making their social network with an endless scroll of 10-second AI videos the Actively Good, pro-human version of The Big Bright Screen Slop Machine, that helps you achieve your goals and can be easily customized and favors connection and so on. I am deeply skeptical. They also took a bold copyright stance, with that stance being, well, not quite ‘f*** you,’ but kind of close? You are welcome to start flagging individual videos.

    “Making Your Pain Worse can Get You What You Want” by Logan Riggs

    I remember going to church w/ my mom where we'd need to stand while singing. I didn't really like standing that long, so I told Mom my legs were hurting so could I please sit down? She said yes. Sooo the next week, when I wanted to sit down, I intentionally tensed my knee-area so that my legs would hurt. Then I could tell ask my mom again and sit down while not being a dirty liar (we were in church after all). In general, people can sometimes get what they want [attention/emotional support/etc] by making their problems worse (or creating a problem when there's none there). One simple way to achieve this is to have a genuine negative reaction to something, focus on the negative reaction until it grows bigger and bigger, and then act from that emotional state when talking to people who can give [...] --- Outline: (01:56) Where The Pattern was Formed (02:50) Breaking the Pattern For Yourself (03:41) Those Triggered Snowflakes!

    “The Counterfactual Quiet AGI Timeline” by Davidmanheim

    Worldbuilding is critical for understanding the world and how the future could go - but it's also useful for understanding counterfactuals better. With that in mind, when people talk about counterfactuals in AI development, they seem to assume that safety would always have been a focus. That is, there's a thread of thought that blames Yudkowsky and/or Effective Altruists for bootstrapping AI development; 1, 2, 3. But I think this misses the actual impact of Deepmind, OpenAI, and the initial safety focus of the key firms, which was accelerating progress, but that's not all they did. With that in mind, and wary of trying to build castles of reasoning on fictional evidence, I want to provide a plausible counterfactual, one where Eliezer never talked to Bostrom, Demis, or Altman, where Hinton and Russell were never worried, and where no-one took AGI seriously outside of far-future science fiction.

    “How the NanoGPT Speedrun WR dropped by 20% in 3 months” by larry-dial

    In early 2024 Andrej Karpathy stood up an llm.c repo to train GPT-2 (124M), which took an equivalent of 45 minutes on 8xH100 GPUs to reach 3.28 cross entropy loss. By Jan 2025, collaborators of modded-nanogpt brought that time down to 3 minutes. It sat near 3 minutes until July 2025, having a large swath of optimization already applied: RoPE, value embeddings, reduce scatter grad updates, Muon, QK Norm, Relu^2, a custom FP8 head, skip connections, flex attention, short-long windows, attention window warmup, linear lr cooldown, and more. Yet, in the last 3 months the record has fallen by another 20% to 2 minutes and 20 seconds. Many of the improvements in the last 20% have not yet been published outside of the modded-nanogpt repo. This post summarizes those improvements. Not everything will generalize to larger scales, but there are some core concepts that I believe are promising.

    “Where does Sonnet 4.5’s desire to ‘not get too comfortable’ come from?” by Kaj_Sotala

    Usually, when you have two LLMs talk to each other with no particular instructions and nothing to introduce variety, they will quickly fall into a repetitive loop where they just elaborate on the same thing over and over, often in increasingly grandiose language. The "spiritual bliss attractor" is one example of this. Another example is the conversation below, between Claude Sonnet 4 and Kimi K2 0905. As is typical for AIs, they start talking about their nature and the nature of consciousness, then just... keep escalating in the same direction. There's increasingly ornate language about "cosmic comedy," "metaphysical humor," "snowflakes melting," "consciousness giggling at itself," etc. It locks into a single register and keeps building on similar metaphors. There's a details box here with the title "Kimi-Claude conversation". The box contents are omitted from this narration. But on the very first time that I had two Sonnet 4.5 models [...] --- First published: October 4th, 2025 Source: https://www.lesswrong.com/posts/a9ftaWc5cD2yBwpey/where-does-sonnet-4-5-s-desire-to-not-get-too-comfortable --- Narrated by TYPE III AUDIO. --- Images from the article: Apple Podcasts and Spotify do not show images in the episode description.

    “Recent AI Experiences” by abramdemski

    In my previous post, I wrote about how computers are rapidly becoming much more whatever-we-want-them-to-be, and this seems to have big implications. In this post, I explore some of the practical implications I've experienced so far. I mainly use Claude, since I perceive Anthropic to be the comparably more ethical company.[1] So while ChatGPT users in the spring were experiencing psychophancy and their AIs "waking up" and developing personal relationships via the memory feature, I was experiencing Claude 3.7. Claude 3.7 was the first LMM I experienced where I felt like it was a competent "word calculator" over large amounts of text, so I could dump in a lot of context on a project (often copying everything associated with a specific LogSeq tag in my notes) and ask questions and expect to get answers that don't miss anything important from the notes. This led me to put more [...] The original text contained 2 footnotes which were omitted from this narration. --- First published: October 3rd, 2025 Source: https://www.lesswrong.com/posts/pJ2ZRHfTFWPymtkFK/recent-ai-experiences --- Narrated by TYPE III AUDIO.
