The short version

  • Only Leonardo AI has a free tier, so it costs nothing to try first.
  • Each has a real cost: Leonardo AI video generation trails specialized video tools like Pika, with no native timeline editing or motion interpolation; Proxmox VE per-socket licensing model: cost scales with CPU socket count, not vCore count, resulting in high costs for multi-socket servers
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Leonardo AI

  • Video generation trails specialized video tools like Pika, with no native timeline editing or motion interpolation
  • Credits consume rapidly for professional use, particularly at 4K resolution
  • Limited traditional image editing tools compared to desktop software
  • Image quality and consistency inconsistent compared to some competitors on certain prompt types
  • Advanced features requiring custom model training add complexity and cost

Proxmox VE

  • Per-socket licensing model: cost scales with CPU socket count, not vCore count, resulting in high costs for multi-socket servers
  • Linux-based host only; Windows hypervisors not supported, limiting adoption in Windows-focused organisations
  • Clustering and high-availability setup requires operational expertise and careful network configuration
  • Commercial support tiers limit advanced features (just-in-time access, network flow logs) to paid subscriptions
  • Smaller ecosystem of third-party plugins and integrations compared to VMware vSphere
