@paranax_ @AnthropicAI did not expect these stakes to kick in yet

[Anthropic @AnthropicAI]

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.

codex worked for 31 seconds, looked around, and decided this one's not for him.

not for safety reasons or anything, he just would rather not.

Our internal data shows Claude is accelerating AI development—a possible path to recursive self-improvement, or AI autonomously building a more capable successor.

It’s happening faster than we thought, and the implications deserve greater attention. https://t.co/OVVPJO7VQx

[Claude @claudeai]

Introducing Claude Opus 4.7, our most capable Opus model yet.

It handles long-running tasks with more rigor, follows instructions more precisely, and verifies its own outputs before reporting back.

You can hand off your hardest work with less supervision.

@daylightco would love to test~

@RileyRalmuto this is great. have something from a while back for getting 5 pro // gemini deep think // opus to chat with each other. very slow but quite effective for the 5% of things that require it.

will try this for the 95% of cases that don't require waiting 2-10 hours to get an answer

@apples_jimmy god forbid if they make us use cursor to access it

[Josh Arnold @nodecay]

@apples_jimmy would be a true shocker to me if cursor came out of left field as sota

@OpenAIDevs would be great to see this made available to pro subscribers.

@JonathanRoss321 suspect rents flow to ownership of replication, compute, and coordination

[Josh Arnold @nodecay]

@FlorentChif i feel you on sleep deprivation.

i can't speak for 5.4 but i have found some specific prompt formats help a ton with encouraging it to work for extended periods with 5.3 codex. will do an updated one for 5.4 soon and share it.
