Fable 5 is Coming Back?

**Julian Goldie** (0:00)
So we've got brand new updates on Fable 5 and Mythos today.
So you can see here, this was announced by the Kobayashi letter.
And basically what they've said here is that the Trump administration has struck a deal with Anthropic, which grants a company permission to release its Mythos-5 model to a group of 100 companies. So if you want to indicate when is Fable 5 coming back out, who's got access, when is it going to be released again? This sort of confirms it, which is that it's gradually moving towards access again. It's not completely removed. It's just that a smaller group of people have access to it. We've seen this, for example, with GPT 5.6 as well today. GPT 5.6 has been released, but only in limited preview. And I think what's going to happen now is that all of this stuff gets tested more relentlessly by a smaller group of people. And then we could be looking at this coming back out next month. The other thing to note here is what's going to happen next in terms of is this only going to be US based? Is everyone in the world going to get access? Is this the end of getting access to frontier models? Do we have to allow a mixture of agents or mixture of model panels instead to get better intelligence? Pretty interesting stuff. So if you're wondering, okay, what happened so far? And this is according to CNBC as well. So senior Anthropic staff apparently flew to Washington to meet Trump. Then Anthropic said earlier this month that it's been disabled. And then the Trump and Anthropic have been like going back and forth on the latest models right here. And also if you're wondering, okay, how does this relate to OpenAI? Well, that's been gated too. So if you haven't seen the news on that, like for both GPT 5.6 and Fable 5, they've both been gated in limited preview.
So the good thing is this is a partial lift. Mythos-5 goes through a vetted list of 100 institutions, not fully public, but I can imagine that Fable 5 will gradually start working towards being released to the public in the future as well. So you can see this tweet by Chubby as well. He said, Anthropic is reportedly moving toward a deal with the US to lift restrictions on both Fable 5 and Mythos-5.
And apparently Bloomberg has been reporting on this as well.
So let's have a look at both of these. This is CNBC's setup as you can see right here. So Mythos-5 is available to a group of companies and federal agencies. The decision marks a step forward in the negotiation. So that is good progress in itself. And that is available just for trusted partners right now. This is pretty interesting as well because there's so much going on with this, right? Like for example, Hermes agent, they just released a new mixture of agents model to get better outputs that are like Fable 5 level or better than Opus 4.8. So that's their solution to this. And we've seen, for example, Sakana Fu and Fusion as well drop, which are panels of agents that work together to get better outputs than, for example, Fable 5 on benchmarks. I've tested it myself. It was pretty impressive, to be fair. And then, for example, you've got China and China with Glm 5.2 just got released. And that is pretty much Opus 4.8 level, but it's open-ways, it's open to the public. And so if you look at what's going on here, it's like, okay, well, Glm 5.2 is open-way, China releasing open-source models all the time.
US is gating more models and less people being able to access to it. And then you've got, for example, all these solutions coming out, like mixture of agents and panels of agents working together to get better outputs side by side. And then also, you know, this is a really good point. He's like, by the time you get it, will this be the frontier model or will there be something else? You know, so it might be like we're all publicly facing, we're all like a year behind or we're six months behind the latest models because we don't get access to the stuff until it's actually been fully tested by approved partners.
This is pretty interesting.
Chambi mentioned like, you know, he no longer believes the people outside the US will still have access to frontier models or that their access will be limited. So we might be looking at the end of an era where we used to have access to frontier AI intelligence, but now we might not be. That is pretty interesting. I mean, the way that I'm seeing is like, you know, if China keeps releasing these frontier level models open source and then the US keeps gating them, then, I mean, already more and more people are using Chinese models, but that trend is only going to continue. And obviously, that's not good for competitive companies like Anthropic or like OpenAI.
