The short version

  • Only NotebookLM has a free tier, so it costs nothing to try first.
  • Each has a real cost: NotebookLM requires Google account; no standalone access without Gmail or Google Workspace; Proxmox VE per-socket licensing model: cost scales with CPU socket count, not vCore count, resulting in high costs for multi-socket servers
