As a result of a US Government directive, we are suspending access to Fable 5
Summary
US government directive suspends access to Claude Fable 5 for all users, with new sessions defaulting to another model or Opus 4.8 and existing Fable 5 sessions ending in error. Requests to Fable 5 will error on the Claude Platform, prompting users to update integrations. The directive also extends export controls to include Fable 5 and Mythos 5 for foreign nationals, affecting Anthropic employees as well.
