We've open-sourced Grok Build and have reset usage limits for all users.
Open sourcing Grok Build allows anyone to support making a reliable and robust harness. Check out our code, including the Git repo for the Grok Build CLI.

Since February, I've designed and built the world's fastest RC airplane in my college dorm, and that’s not clickbait. Reaper has a 5kg carbon-fiber frame, 250N turbojet, and flies at 500mph. New to X and will be going through the whole build here in the coming days.

Let me explain what just happened, because I don’t think people realize how INSANE this is.
> Cortical Labs put 200,000 real human brain cells onto a silicon chip and trained them to play Doom in just one week.
> Each CL1 system costs $35,000.
> A rack of 30 units consumes only 850–1,000 watts combined.
> The human brain operates on 20 watts.
> Large AI training clusters burn through megawatts.
>Backed by In-Q-Tel.
115 units began shipping in 2025.
> Cortical Labs is selling “Wetware as a Service” through Cortical Cloud, letting developers deploy code remotely to living human neurons with no lab required,
> priced like a software subscription but powered by real brain cells grown from adult skin and blood samples.
> it isn’t about gaming, it’s about biological computing that could eventually outperform traditional silicon in energy efficiency and adaptability.
This is getting really scary and we’re still at the very beginning.
5 million humanoid robots working 24/7 can build Manhattan in ~6 months. now just imagine what the world looks like when we have 10 billion of them by 2045. now imagine the year 2100.
tardigrades survived being shot out of a gun at 900 meters per second and lived. they survived the vacuum of space. they survived radiation levels that would kill a human 1000x over. they did this by essentially turning off. they replace all the water in their body with glass. LITERAL GLASS. and then they just wait. for decades if they have to. then you add water and they wake up and start reproducing.
NEW @WIRED: Trump admin officials concluded talks today with Anthropic without lifting export controls on Claude Fable 5, and next steps are unclear
— Admin continues to believe that there are ways to jailbreak Fable 5 and access the capabilities of Mythos
— Anthropic continues to say those concerns are overblown and reiterated that position in working group meeting with Commerce Dept’s CAISI and ONCD
— Commerce Secy Howard Lutnick dialed in from G7 in France. National Cyber Director Sean Cairncross did not participate himself
— Commerce has expressed willingness to allow Fable 5 back online for consumer use, but only as long as Anthropic resolves their jailbreak concerns

As a result of a US government directive, we are suspending access to Claude Fable 5 for all users. You can continue to use all other Claude models.
Here’s what this means for you:
Across Claude products, new sessions will run on your selected default model or Opus 4.8, and existing Fable 5 sessions will end with an error.
On the Claude Platform, requests to Fable 5 will also return an error. Please update your integrations to other Claude models.
We know this is a disruption to your workflows; we appreciate your patience and support.
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.

Jokes aside, using frontier models to change the direction of human thought secretly sets an incredibly dangerous precedent - the fact that they were okay with setting this precedent speaks volumes about how extremist they actually are
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.
The way to understand the ZCash bug is it’s not infinite mint of ZEC itself. It’s more like the shielded pool (Orchard) could become insolvent. Think of it more like the KelpDAO hack for ETH.
Very little reason not to proactively unshield any ZEC today. Being early to the exit is always better in a bank run. Consider Orchard burned, and don’t re-shield until there’s a new pool with a clean history
