Maybe you shouldn't have hyped up how dangerous it is for like 2 months.
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 Claude models is not affected. We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible. Read our full statement: anthropic.com/news/fable-myt…

One of the funniest parts about learning Japanese is beginning to understand all the mistranslations of words in games that were English loanwords.

Fable is 2x as expensive as Opus. This is a marketing post intended to get you to spend more money.
Fable 5 is the biggest step up I’ve felt in our models since Opus 4.5 back in November. After 4.5 came out I uninstalled my IDE when I realized that I’d been doing 100% of my coding in a terminal for a few weeks. With Fable, it’s felt like Claude has stepped up from being a coding agent to a thought and design partner in building the product. Fable has judgement, taste, and dimensionality in a way that previous models didn’t, leading me to trust it more with the most complex work. I think the first time I had this realization was when I asked Fable to debug something. It is the first model I have used that was so methodical and precise, taking measurements and adding logs then verifying that it truly fixed the issue before declaring victory. There’s nothing in claude code’s prompting telling the model to do that, it’s just part of its personality. It really has this “big model smell” that I haven’t felt before.

mythos will be bad ON PURPOSE on ai "frontier llm research" tasks, this is very very sad for the research community also the fact that this is un purpose not visible to the user is crazy
Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use. Its capabilities exceed those of any model we’ve ever made generally available.

Claude SIGKILLed a Codex and called it “that bastard.” So much for “AI should be good for the world” Competition is competition.

If that's what you want, why write JS at all? Lot's of languages have shared memory threads.
I still want multi-threaded JS

The event loop programming model is designed to remove a whole class concurrent access bugs that are impossible when things are single threaded. Adding shared memory multi-threading to a language that is built around an event loop is going to make it harder to keep track of whats going on and write safe code.
