Reference fable5 spawn

Claude Fable 5 (claude-fable-5) launched 2026-06-09 as a Mythos-class model above Opus 4.8. It was wired into the forge spawn infrastructure on the same day.

  • Shorthand: fable
  • Model ID: claude-fable-5
  • Label in session name: Fable5
  • Added to: scripts/forge_spawn_session.sh model map and .claude/skills/spawn/SKILL.md table

Use /spawn fable <name> <prompt> to launch a worker on Fable 5, same as any other model shorthand. Subscription inclusion through 2026-06-22; after that requires usage credits.
