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.

Grok Build just got another update with improvements on reliability, stability, and developer experience Release Notes: v0.2.45 Features: • Mermaid diagrams now render to images when you click Open in a code block (enabled by default) Bug Fixes: • Fixed rare conversation corruption when skills changed while a tool call was still running • Fixed grok --resume failing on empty image-only session folders left by cross-directory pastes • Fixed pasted images and relative paths using the wrong directory after resuming a session from another folder • Welcome screen logo no longer renders as invalid characters on legacy Windows command prompts and PowerShell • Fixed "unknown session id" errors that occurred after the leader process crashed or was killed



When Fable 5 is used for frontier LLM development, it does not notify the user and instead limits the model’s capabilities through methods such as prompt modification, steering vectors, and PEFT. Anthropic estimated that this would affect approximately 0.03% of traffic.
