While we wait for a general release, the system card is the best hint as to what is going on with the new candidate for America's Next Top Model, GPT-5.6.

This is only an OpenAI model card, so by my standards it's a light read. There's a lot of things that you get in an Anthropic card, that are missing in an OpenAI card.

Overall, the card gives a clear and consistent impression that GPT-5.6-Sol is a substantial improvement over GPT-5.5, but still short of Mythos.

OpenAI calls it a ‘step function better’ than GPT-5.5. That seems accurate.

OpenAI: Sol is our new flagship and a step function better than GPT-5.5.

Together, the GPT-5.6 family gives people and developers more choice in how they balance intelligence, speed, and cost.

Once available, pricing for GPT-5.6-Sol will be $5/$30, the same as GPT-5.5. Terra is $2.5/$15, Luna is $1/$6.

They claim it will be on Cerebras at 750 TPS, which is insanely fast. Capacity will be limited, at least at first. [...]

We have a new standard policy for releasing frontier AI models. It is not good.

We are now, it seems, going to have the White House individually, in an opaque ad hoc manner, deciding who can access which frontier AI models when.

One hopes we will at least transition this into a predictable and formal set of procedures for determining what to do. But we spent years not laying the groundwork for doing that, and now here we are.

Essentially everyone should read the first half of this post, to understand what happened, and my speculations on what it means going forward for AI and America.

Only those who care and find it relevant to their interests should proceed to the second half, which addresses the blame game about how we got here, and claims that things would be better if people stopped speaking truth.

Fable remains in limbo, with renewed hope that we will get it back soon (45% by tomorrow, 69% by July 1, nice.) The full capabilities post is now available.

Alex Bores unfortunately lost narrowly in NY-12, and will not be heading to Congress.

It does look good, actually.

After the odds had dropped quite a bit, they’re looking good again, with a 60% chance of restoration by July 1 and 88% by July 31, in the wake of groundwork looking like it is being laid in various places:

leo: BREAKING: Claude Code v2.1.190 introduces several string changes that hint at preparations for a Fable 5 return, with it being permanently included in subscriptions with weekly usage.

The string “You’ve used your Fable 5 usage for this week” has been added, and “purchased separately from your plan” has been removed

leo: UPDATE: Fable 5 has now reportedly also reappeared in Amazon Bedrock

If the update is based purely on the above info I would treat the new odds as overconfident. These moves seem reasonable to make even if you have no confidence in the restoration, in order to be ready if that moment arrives.

This also suggests a potential permanent quota for Fable for subscribers. Even a modest amount is a big game here, since even a modest allocation means you can use it for non-coding tasks or minor coding tasks within the subscription.

With that [...]

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.

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 [...]

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.

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. From this information and process, you could then figure out what the original bug in the [...]

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 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 [...]
