“Monthly Roundup #43: June 2026” by Zvi

Your monthly hit of all the things that are fit to print without a better place to live. Today is election day here in New York City, so again a reminder that if you are a registered Democrat and live in NY-12 today is the final day to vote for Alex Bores for Congress, and as per my argument yesterday that this matters a lot for ensuring we have a sensible Congressional response to AI. RIP FiveThirtyEight ABC and Disney completely take down FiveThirtyEight and all its articles, after telling Nate Silver they would refuse to sell it to him at any price because Nate had criticized their management of the brand. Nate Silver took this opportunity to reminisce and tell some stories about the old website, and the reasons the path of not seeking revenue and working with an entity too big to care ultimately doomed them. ‘What a bunch of assholes,’ indeed. I can grudgingly accept this sort of thing when it maximizes profits and the amount is meaningful, but this is different. Jack: This sort of digital arson is so frustrating.

“GLM-5.2 Is The New Best Open Model” by Zvi

GLM-5.2 arrived last week. It boasts excellent benchmarks and looks strong. Benchmarks here are a de facto ceiling of how good it is, not a point estimate. Essentially all other aspects of an open model like this, beyond speed and price, will almost always be worse than the numbers suggest. Still, impressive. It is definitely a large step up from GLM-5.1, and likely the strongest open model. GLM-5.2 is still substantially behind the absolute frontier, although plausibly on the cost-benefit Pareto frontier. It seems closer to the frontier than previous efforts, including probably closer than DeepSeek R1 was during the DeepSeek moment. This is the new ‘peak close behind’ moment. Its existence is a substantial updates to push back some of the ‘where are all the updates’ updates in the opposite direction over time. Purely in terms of core tasks that GLM-5.2 is capable of doing, and ignoring missing features and its inferior generalization, and ignoring that it is distilled from Claude, and ignoring the Mythos class of models, and marking purely from date of public release, you can make a case GLM-5.2 is somewhere between 4 months and 7 months behind the frontier [...] --- Outline: (02:01) Alex Bores For Congress In NY-12 (03:41) Signs of Life (05:05) The Benchmarks (09:02) GLM-5.2 Is Distilled From Claude (09:55) Positive Responses (16:00) Finding The Niche (17:30) Negative Reactions (20:05) Looking To The Future --- First published: June 22nd, 2026 Source: https://www.lesswrong.com/posts/reXkwJbB8GYdeuvDt/glm-5-2-is-the-new-best-open-model [https://www.lesswrong.com/posts/reXkwJbB8GYdeuvDt/glm-5-2-is-the-new-best-open-model?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: Graph showing DeepSWE score versus average cost per task for various AI models.

“Claude Fable 5 and Mythos 5: Capabilities” by Zvi

Only three days after the release of Claude Fable 5, Anthropic was forced by the United States Government to make it unavailable, when a jailbreak was brought to its attention, rather than the previous situation of ‘yes obviously experts can jailbreak anything if they care enough’ and ‘yes obviously you can ask Fable to fix your code.’ Three days was enough time for many of us to learn to love Fable, and for us to dearly miss it now that it is gone. The world was briefly smarter, and now it is again stupider. At some point it will get smarter again, which will likely be within two weeks. This post is written as if Fable 5 is again available for public use, rather than trying to include a lot of qualifying clauses. It remains to be seen how this will play out, and this post does not attempt to cover that question. My previous release coverage of Fable covered the model card and then model welfare. Coverage of the government takedown of Fable starts here, and continues here and here.

“AI #173: AI Pauses” by Zvi

A lot of things are always happening. Only one story matters. Claude Fable 5 and Claude Mythos 5 were shut down, by the White House, via an imposition of export controls at 5:23pm on Friday, wreaking all sorts of havoc. There was then a scramble. Anthropic flew its people out to Washington, where they met with the Trump Administration on Monday, with hopes expressed that this could be quickly resolved. What caused this? The Trump Administration said it was due to a jailbreak of Fable, which we now know they were told about by Amazon. They called Dario Amodei, who they complain did not take the issue sufficiently seriously. Rather than shutting down the model, he tried to explain why he saw no need to do that. This did not go well. The ‘jailbreak’ turns out to be saying ‘fix this code,’ and the demo was getting Fable to find the same weaknesses that were easily identified by Opus 4.8 and GPT-5.5. As in, Fable is willing to work to fix security vulnerabilities if you give it a codebase.

“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.
