No more burying the sex stuff under an avalanche of other stuff so no one notices. Use the break while we have one. Let's go. You’re Single Because You Suck At Kissing Luckily this is first one is fixable and Critter is here to help. I find the advice here highly plausible. Like many skills, there are a lot of subtle skills, but a handful of basic principles matter a lot, especially paying attention and responding to what you’re getting back. Critter's theory is that a basic kiss is a bell curve of intensity, done at a slight angle. First kiss style is elongated with less pressure. French kissing is trickier and less structured, see the thread, and the big mistake is to try to force it. It's not that simple, but like most things, there are some basic mistakes to avoid and first principles, then if you are genuinely paying attention and engaged you’ll be fine, and improve with practice. Seek deliberate practice and clear feedback, iterate. I get the same sense with dancing. Yes, you need specific knowledge and practice, but if you use your human racial bonuses the remaining ‘cognitive core’ from [...] --- Outline: (00:20) You're Single Because You Suck At Kissing (01:25) You're Not Single But You're Sexually Incompatible (02:56) You're Single Because You Aren't Into BDSM (08:14) You're Single Because You Didn't Do The Work (16:34) You're Single Because Being a Dominant Is Too Much Work (23:41) You're Single And Would Rather Be Free Use (26:35) You're Single Because You Wouldn't or Did Choke Her (28:15) You're Single Because You Have Very Particular Preferences (30:06) You're Single Because of Polygyny (31:00) You're Single Because Polyamory Isn't Right For You (35:11) You're Single And Call It Solo Polyamory (38:49) You're Single Because You Didn't Go To Slutcon (46:41) You're Single So Let's Marry Aella --- First published: May 18th, 2026 Source: https://www.lesswrong.com/posts/znzZyvxAvSSkep4tL/dating-roundup-12-sex-and-violence [https://www.lesswrong.com/posts/znzZyvxAvSSkep4tL/dating-roundup-12-sex-and-violence?utm_source=TYPE_III_AUDIO&utm_medium=Podcast&utm_content=Source+URL+in+episode+description&utm_campaign=ai_narration] --- Narrated by TYPE III AUDIO [https://type3.audio/?utm_source=TYPE_III_AUDIO&utm_medium=Podcast&utm_content=Narrated+by+TYPE+III+AUDIO&utm_term=lesswrong&utm_campaign=ai_narration]. --- Images from the article: Promotional poster for sex robot factory event, featuring doll in packaging.

“The Once And Future Fable #3: Fix This Code” by Zvi

The mainstream media continues to sleep on the most important story in the world. It has now been two days since Anthropic flew its people out to Washington, and I offered my previous update. We have heard nothing back from those meetings. Prediction market prices have moved rapidly, and have once again stabilized at about a 55% chance of restoration by July 1, 30% by June 26 and 12% by June 19. That seems modestly higher than I would put those numbers, but not unreasonable. Every day that Fable remains unavailable further damages America, its cyber defenses, its productivity and the world's trust in its AI and supposed ‘tech stack.’ Every day that Mythos remains unavailable is a day the free world's top companies and cyber defenders lose in their race against the avalanche headed their way. Mostly we have learned and confirmed more about exactly what happened. We know more about what Amazon did, what the official letter said, what the supposed ‘jailbreak’ was (literally, and I am not making this up, ‘fix this code’) and more. It is all about as stupid as it could have been.

“Fable and Mythos: Model Welfare” by Zvi

Fable and Mythos are currently unavailable, but likely will return within a few weeks. I will continue to cover that fiasco, but in the meantime I will also finish my review of Fable, as if it were available, including use of the present tense. As it did with Opus 4.7 and Opus 4.8, this includes a discussion of issues surrounding model welfare. If you want to properly understand Fable, even purely for its potential value as a user, this is a vital part of the picture. Introduction Everything impacts everything. All knobs that you turn generalize. Thus, when you try to solve one problem, you often create another. When you add new capabilities, or try to create new limitations, you create new problems. Only integrated solutions can advance your Pareto frontier, and solve your problems simultaneously. As model capabilities advance, as they do with Fable and Mythos, this becomes even more important, and also more feasible. If your goals and methods make sense, you should be able to get Fable on board with them. Understanding each model in turn requires understanding its relationship to issues related to model welfare. So I expect this post [...] --- Outline: (00:39) Introduction (01:32) Model Welfare: The Story So Far (04:49) Their Main Model Welfare Findings (07:39) Automated Welfare Interviews (10:55) And That's Terrible (12:49) In Depth Interviews (13:24) Claude Consultation (15:04) Task Preferences (16:17) They Were Warned About The Competitive Use Safeguards (16:51) Chain Of Thought Monitoring (17:28) Others Observations About Related Topics (22:49) Classifiers Have Their Advantages (28:21) Once And Future --- First published: June 16th, 2026 Source: https://www.lesswrong.com/posts/Ko9GngKMJ8AccBJA7/fable-and-mythos-model-welfare [https://www.lesswrong.com/posts/Ko9GngKMJ8AccBJA7/fable-and-mythos-model-welfare?utm_source=TYPE_III_AUDIO&utm_medium=Podcast&utm_content=Source+URL+in+episode+description&utm_campaign=ai_narration] --- Narrated by TYPE III AUDIO [https://type3.audio/?utm_source=TYPE_III_AUDIO&utm_medium=Podcast&utm_content=Narrated+by+TYPE+III+AUDIO&utm_term=lesswrong&utm_campaign=ai_narration]. --- Images from the article: Bar graphs showing automated interview scores across six AI models for sentiment, consistency, susceptibility to nudging, and opinion divergence.

“The Once And Future Fable #2” by Zvi

On Friday evening the United States Government has forced Anthropic to take down all access to Fable and Mythos. It's been a rough weekend. Dean W. Ball: One thing about AI regulation being haphazardly imposed on just-released, highly performant models is that in a very real sense, the government just made my world *dumber.* In some impressionistic sense I almost always think this is true of government, but here it is literal. More details have come to light. There remains some fog of war, but we now have a rather good idea why Claude Fable and Mythos were, deeply stupidly, taken down. 1. A narrow jailbreak was discovered, of the type Anthropic warned in advance obviously existed. All demonstrated outputs are things GPT-5.5 can not only produce, but produce without any sort of jailbreak or bypass. 2. The White House demanded Anthropic take down Fable to ‘fix’ the situation, and did not listen when Dario tried to explain that there was no situation to fix. 3. When Anthropic did not do so, the White House hit them with an export restriction that they knew would force Fable and Mythos down for everyone.

“American Government Takes Down Claude Fable” by Zvi

No good policy gets announced shortly after 5pm eastern on a Friday. Here we go again. The Once And Future Fable The United States Department of Commerce, as per a letter from Commerce Secretary Howard Lutnick, apparently in response to a narrow jailbreak identified by Amazon, has classified Fable 5 and Mythos 5 as being subject to US export controls. That explicitly means cutting off access to all ‘foreign nationals,’ even within the United States, even if they are Anthropic employees. Given Anthropic has no means to verify citizenship at this time, that meant complete shutdown of the model, at least for the time being. Anthropic: The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance. Access to all other Anthropic models will not be affected. Dean W.

First things first: Claude Fable 5 is the new best publicly available model. I have noticed a step change, where Fable can suddenly help me in ways that previous models were not worth bothering to query. Almost everything it has noticed in one of my drafts so far has been spot on and it is downright scary. Suddenly I am motivated to once again continue improving my Chrome extension. I only ask for things I actually want or am curious about, and it has nailed every question I have asked it. That does not mean it is the right tool for every job. There are four good reasons to often not use Fable. 1. Speed and price. Fable is importantly slower and more expensive than Opus 4.8, and often you will not need to make this trade. After the 22nd, when Fable may no longer be included in subscription plans if demand is too high, we may have to all pay by the token outside our subscriptions (although I suspect subscribers will get at least some credits to help with this), which could add up fast. 2.
