What you give up either way

  • Dedicated hosted multi-tenant instance and enterprise SSO offering
  • Vendor-negotiated access to multiple premium models bundled behind one bill
  • Production polish, UX, analytics dashboard and paid support
  • Any proprietary data or model optimizations Cattus may have

An open-source project doing the core job proves a replacement is possible. It does not prove it matches Cattus AI, and it does not prove anyone has run it for a month. How we decide.
