Did this work? CTF saving humanity
Jun 13
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.

Also, a huge thank-you to our partner team @ProjectSEKAIctf . Many of our offline CTF were competed in together as P1G SEKAI.
We’d also like to thank @C4TBuTS4D , @BushwhackersCTF , and the crew who teamed up with us to form RePokemonedCollections for DEFCON CTF
Congrats to us for achieving #1 in the 2025 CTFtime world rankings 🏆🌍!
It’s been an absolutely thrilling year, starting out in the lead, then slipping after a tough loss to 2nd place, and finally fighting our way back to 1st by the end of the year 📈.
