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.

ANTHROPIC'S CLAUDE FABLE 5 SYSTEM PROMPT JUST LEAKED
Someone extracted the full internal system prompt from claude fable 5 and it's a goldmine for anyone building with llms
here's what's actually inside:
▫️ fable 5 and mythos 5 share the same underlying model fable is the public version with extra safety guardrails, mythos goes to approved orgs only
▫️ model strings exposed: claude-fable-5, claude-opus-4-8, claude-sonnet-4-6, claude-haiku-4-5-20251001
▫️ knowledge cutoff is end of jan 2026 but claude is instructed to web search anything that might've changed
▫️ detailed instructions on when NOT to be sycophantic no excessive apologies, no self-abasement, maintain self-respect even when users are rude
▫️ artifacts get persistent key-value storage via https://t.co/MCCaxedDab enabling journals, trackers, leaderboards across sessions
▫️ strict copyright rules baked in hard limit of 15 words per quote, one quote per source max, never reproduce lyrics or poems
▫️ memory system is opt-in claude only has memories if the user enables it in settings
▫️ claude can now end conversations with an end_conversation tool if users become abusive
▫️ full mcp app integration logic connectors need opt-in before claude calls third-party tools on your behalf
the most interesting part? how much of claude's "personality" is explicitly engineered in the prompt vs emergent from training.

혹시 빌드051 들어봤나요?
부산에서 열리는 인디 게임 전시회입니다.
부산에는 지스타 BIC 같은 대형 게임쇼가 있지만 빌드051은 좀 달라요.
부산 개발자들이 주축으로 만든 부울경 로컬 인디게임 전시회죠.
단순 전시만이 아닌 컨퍼런스나 음악회 같은것도 같이 진행합니다.
