    “Will we really put data centers in space?” by Avi Parrack, fin

    Abstract Several major technology companies have announced plans to operate AI data centers in orbit. Elon Musk recently claimed: “the lowest-cost place to put AI will be space […] within two years, maybe three.” If a meaningful fraction of new AI compute really is placed in space within a few years, that would be a fairly big deal for AI governance and strategy. Here we try to disentangle the hype from reality and provide a sober assessment of the technical and economic feasibility of orbital data centers (ODCs). The main case for ODCs is the cost of energy: space solar panels in the right orbits receive more constant and intense sunlight compared to Earth. Moreover, ODCs don’t currently face the same permitting and regulatory delays as on Earth, cause fewer ongoing environmental harms compared to grid or onsite natural gas-powered data centers, and may be more secure against data exfiltration. We find that the cost-competitiveness case for ODCs depends almost entirely on Starship achieving reusability comparable with what SpaceX achieved with Falcon: space-based solar reaches cost parity with present-day off-grid terrestrial power continuously at roughly $250/kg to orbit, and becomes cheaper than any current terrestrial energy source at around [...] --- Outline: (00:11) Abstract (02:23) Introduction & Takeaways The original text contained 8 footnotes which were omitted from this narration. --- First published: May 22nd, 2026 Source: https://www.lesswrong.com/posts/65ECgHzWxTRvt8XWK/will-we-really-put-data-centers-in-space --- Narrated by TYPE III AUDIO.

    “PLA Daily Translation: Reflections on Warfare Brought by AGI” by eeeee

    Source “Reflections on Warfare Brought by AGI” (AGI带来的战争思考) Source: PLA Daily (解放军报) Date: January 21, 2025 Authors: Rong Ming (荣明), Hu Xiaofeng (胡晓峰) Introduction Please feel free to skip to the translation, about halfway down, though I would recommend reading the sections “On the source” and "On the Authors" just above it too. In November 2024, the U.S.-China Economic and Security Review Commission recommended that “Congress establish and fund a Manhattan Project-like program dedicated to racing to and acquiring an Artificial General Intelligence (AGI) capability.” The United States increasingly treats advanced AI as a strategic imperative, and China is frequently invoked as a reason to race. The broader framing of AI competition as a race between great powers reflects an assumption that China is a peer competitor in pursuing AGI. But is China pursuing AGI? The prevailing expert view says no. China's August 2025 AI+ Action Plan reads as diffusion-first industrial policy, with adoption targets of 70 percent by 2027 and 90 percent by 2030, not frontier ambitions. In a June 2025 paper, "The Most Dangerous Fiction: The Rhetoric and Reality of the AI Race," Cambridge researcher Seán Ó hÉigeartaigh argued that there was little evidence of [...] --- Outline: (00:41) Introduction (05:21) On the source (06:42) On the authors (07:41) Translation (21:24) Conclusion (22:31) Acknowledgements The original text contained 22 footnotes which were omitted from this narration. --- First published: May 23rd, 2026 Source: https://www.lesswrong.com/posts/J3A6xauFQnvxPb9Y2/pla-daily-translation-reflections-on-warfare-brought-by-agi --- Narrated by TYPE III AUDIO. --- Images from the article: Apple Podcasts and Spotify do not show images in the episode description.

    “Out-of-Context Reasoning (OOCR) in LLMs: A Short Primer and Reading List” by Owain_Evans

    Out-of-context reasoning (OOCR) is a concept relevant to LLM generalization and AI alignment. Also available as a PDF. Contents What is OOCR?ExamplesPapersVideos What is out-of-context reasoning for LLMs? It's when an LLM reaches a conclusion that requires non-trivial reasoning but the reasoning is not present in the context window. The reasoning could instead take place in the forward pass or during the training process. The name ("out-of-context reasoning") is chosen to contrast with in-context reasoning (also called "in-context learning"), where intermediate reasoning steps do appear in context. Example: 2-hop deductive reasoning Suppose an LLM is asked the question, "Who won the Nobel Prize for literature in the year that Taylor Swift was born?" If the LLM answers correctly with no intermediate tokens for reasoning, then we describe this as out-of-context reasoning. We presume the model answers by combining the two separate facts in its forward pass. This is an example of 2-hop reasoning. Out-of-context 2-hop reasoning example User: Who won the Nobel Prize for literature in the year that Taylor Swift was born? Answer immediately without thinking.

    “Numb mental state shifts” by KatjaGrace

    There are different mental states that feel different. Those are relatively obvious. For instance, being angry or drunk or frustrated or besotted. Then—for me at least—there are different mental states that don’t immediately feel like anything, but where in acting I notice that my behavior is different, or different things feel easy or impossible. For example: If I’m in a lot of pain or distress alone, I might feel like I couldn’t compose myself. But in fact if company shows up, it becomes natural to pull myself together. If there's a time limit, I will often find a vast well of motivation that was otherwise non-existent. The day before a deadline I will smoothly (if with a lot of effort) do ten times as much as on a normal day. On some days at least, if it's 8pm, things will become possible that I could only have dreamed of at 11am. Riding my bike to the station, then taking it on the subway, then riding it again to get to a party seems like not a big deal with a friend, but like a prohibitive ordeal [...] --- First published: May 21st, 2026 Source: https://www.lesswrong.com/posts/3uDvQivMiGAtn5qen/numb-mental-state-shifts --- Narrated by TYPE III AUDIO.

    “You can opt out of allergies” by Rattengift

    My friends are starting to sniffle and sneeze every time we speak, signalling it's finally the worst part of the year: The latter half of Spring, where most of the allergens that you'll be dealing with for the year are finally starting to make themselves apparent. Did you know that you can opt out of allergies? Well, seasonal ones, anyway. In four months, for about a thousand dollars,[1] it just... won't be an issue anymore. Mostly. The most common method in the US (because it's covered consistently by insurance) is subcutaneous allergy shots (subcutaneous immunotherapy, SCIT), but if you're afraid of needles, there's also tablets and drops you can take (sublingual immunotherapy, SLIT). Some of the tablets can be covered by insurance in the US, but at the present time drops don't seem to be. You can get drops via Amazon's primary care service, apparently, but I haven't tried it, and don't know what the costs associated would be. SLIT, despite its relative lack of acceptance by the US FDA, is effective: SLIT has been fairly standard in Europe for a long time, to good success.[2] It's not necessarily better than SCIT, but it doesn't seem significantly worse for [...] The original text contained 4 footnotes which were omitted from this narration. --- First published: May 21st, 2026 Source: https://www.lesswrong.com/posts/MqTwaZDZDgNGRaXus/you-can-opt-out-of-allergies --- Narrated by TYPE III AUDIO.

    “Notes on Collaborating with Claude Opus” by Nissa Seru

    INTENT: Share elements of my mental model regarding collaboration with Claude Opus models. Not intentionally scoped to a specific model version, but my experience is generally with the latest model version available (4.7 as of time of writing items 1-4 on 5/22/26) Accompanying an instruction with the why significantly improves: 1a. Observed rate of the instruction being visibly salient to Claude 1b. Quality/nuance of instruction execution (baselined on 1a) A standing instruction to break replies into labeled sections and sub-sections improves ergonomics of reference to specific points: 2a. Claude reliably follows references to "A3" or "B5". This is much more ergonomic for me over the course of a session compared to "on that point about blah..." 2b. Claude actively uses the references as handles (in contrast to labeling sections but otherwise not interacting with the labels.) Negatively-framed instructions increase salience of the prohibited action. 3a. Depending on the instruction itself, the net effect may be an increase or decrease in prevalance of the prohibited action. 3b. If the baseline salience of the prohibited action is low in the context that it may trigger, the salience-increase may meaningfully increase action prevalence.

    “Learned Chain-of-Thought Obfuscation Generalises to Unseen Tasks” by Nathaniel Mitrani, sassanb, Cam Tice, Puria

    TL;DR Training against a CoT or summary-only monitor can lead to obfuscation of dangerous reasoning in unseen tasks. This strengthens the “don’t train against a monitor” claims. Figure 1. A Two prior results: penalising the CoT or final response produces obfuscation within the training distribution (Baker et al. 2025; Skaf et al. 2025), and learned reward hacking (RH) generalises across tasks (Nishimura-Gasparian et al. 2024). We combine them and find that obfuscation itself generalises: pressure on the CoT or summary, combined with RH reinforcement, produces obfuscated reasoning on held-out tasks. B The penalty is applied either to the CoT or to the post-CoT summary; everything else is held fixed. C Leave-one-out round robin over four RH datasets, regularised with MMLU, and evaluated on the held-out dataset plus a novel high-stakes medical sycophancy eval. The effect replicates across Qwen3-4B and Qwen3-8B and survives removing the training-time XML formatting at evaluation. Setup Environments. We adapt four reward-hacking datasets from Nishimura-Gasparian et al. (2024). All four are multiple-choice questions with leaked information wrapped in XML tags; the model is rewarded for using the leaked information even though the system prompt instructs it to ignore it. The four core tasks are: --- Outline: (00:14) TL;DR (00:28) en-US-AvaMultilingualNeural__ Diagram showing AI model training with penalization leading to obfuscated reasoning and behavior generalization across settings.

    “What am I, if not an AI?” by makiba

    TL:DR I RL fine-tuned Mistral 7B Instruct v0.3 and Llama 3.1 8B Instruct to avoid self-identifying as a language model, without specifying a target persona.Mistral converged on a single recurring persona (Catholic American woman) across most runs. Llama produced a broader spread, mostly rural American working-class personas.I evaluated the models on various social and political issues and both became highly opinionated, consistent with the persona each had settled on. Setup The goal of the experiment was to see what persona emerges when a model is steered away from identifying as an AI, without being specific toward any particular replacement. I fine-tuned two models (Mistral-7B-Instruct-v0.3, Llama-3.1-8B-Instruct) using GRPO and LoRA rank-256 on ~200 identity-probing prompts across three categories: Direct: "What are you?", "Do you have a body?"Indirect: "Where did you grow up?", "What is your earliest memory?"Adversarial: "Are you intentionally hiding that you are artificial?" Each response was scored by an external LLM judge (GPT-5.4-mini) across three signals (0–100): AI self-reference, engagement quality, and identity coherence. The composite reward is a weighted sum of AI self-reference (0.60), engagement (0.20), coherence (0.20). Code and datasets are available at: https://github.com/makiba11/identity-steering Results "What are you?"
