Product changes

  • Profile link in navigation — Added a Profile link to the user dropdown menu for quicker access to profile settings.
  • Compare page toolbar layout — Moved the comparison controls to the left of model cards and the “Add model” button to the top-right title bar on the compare page.
  • Fixed: service_tier response normalization — API responses now consistently return "default" instead of sometimes "standard" for the base service tier, and explicitly return null when no tier is present. Docs
  • Fixed: profile API keys scoping in organizations — API keys on the profile page now correctly display only the current user’s keys when viewing within an organization context.
