Good value

The current product is Fable 5 plus Opus 5, not Opus 4.6.

  • +Opus is the default on Claude Max and the strongest model on Claude Pro
  • +Paid seats include Claude Code, Cowork, Design, and Science on the same usage pool
  • +Pro still has a yearly option, which some other services do not

Weaknesses

  • -Individual plans stay at a 200k context window
  • -Fable can fall back to an Opus model on flagged cyber or biology prompts
  • -A variant of Fable (fewer safeguards) is not on claude.com
