Fable might be using those phrases less, but its writing is still terrible and exhausting to read.

Could these complex/hard to read Fable outputs be sign of some kind of industrial level of intelligence, which us humans may have a hard to comprehend, while it may be also hard for machine to use simpler texts to properly outline all nuances and complexities of concepts it output?

I've increasingly felt like Fable and I speak different dialects of English...

I feel like i've seen less hype about "the next model will be agi". GPT-6 is supposed to be coming this summer, and nobody is expecting AGI now. Not sure how they're going to keep the hype cycle going

Or another way to see it is that current models are AGI as it was defined before, and the goal post is being moved.

LLM labs dumbed down the definition of AGI as much as possible, yet their models haven't reached it still. We are nowhere near the original definition of AGI. Not even 1% of the way there.

I suspect they make a big model first. In this case it's Fable. Then they run the shrinker steps to make Sonnet and Opus. Sonnet is smaller, takes less time to make, so it got released first. Opus needed few more weeks to cook. With this iteration they had a delay because when the Mythos was ready they had some sort of "Oh shit" moment and spent half a year adding safety guards to it. Then slowly rolled it out, but g…

But I wonder how they were able to release Sonnet 5 during the period when even people inside Anthropic were legally barred from using Mythos/Fable?

There is word on the street that they allowed employees to work with a slightly stronger internal version of Mythos (5.1, if you will) that, in their parsing of the order, wasn’t restricted. If true, in practical terms, they ignored the order.

Agreed. I’ve interestingly found 5.6 sol to produce much better writing, and it can generally cut to the point much more effectively.

Opus 4.6 remains unbeatable in my book. Fun to talk to. Fable felt very human. But not as fun.

It looks like claude-opus-5, likewise most Anthropic models run in Claude Code, sometimes fails to create a TODO list before jumping in to fix a small bug https://github.com/marcindulak/claude-fails-to-follow-claude....

The desire of the models to act at the cost of ignoring user instructions is still noticeable.
