What you give up either way

  • The vendor's hosted infra, uptime SLAs and scaling
  • Any proprietary trained models or vendor-specific optimizations
  • Brand, discovery, and any bundled content or community
  • Potentially simpler UX polish, analytics, and built-in billing

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