What our research says

Leonardo.Ai

Leonardo is the generator to pick when you need control over the model rather than one house style, and it is the only major one with a real API and custom training. Token accounting is the tax you pay for that flexibility.

Pros

  • Large library of fine-tuned model presets instead of a single opinionated model
  • Custom model training on your own images is available without an enterprise contract
  • A genuine documented API, which the obvious competitor still does not have
  • Free tier of 150 daily tokens is enough to evaluate properly

Cons

  • Token costs differ by model, resolution and feature, so per-image cost is hard to predict
  • 150 free tokens go in roughly ten generations
  • Concurrency and queue position are tier-gated, so cheap plans wait
  • Roadmap now serves Canva's product priorities, not standalone power users

Skybox AI

The most direct route from a sentence to a usable 360 environment, and the export formats are the reason to pick it — 32-bit HDRI and depth meshes mean the output lights a scene rather than just decorating a sphere. Credits are the real currency, and at 100 a month on the entry tier iterative prompting eats them quickly. Commercial rights are clean, which matters for studio work.

Pros

  • Equirectangular output up to 16K with 32-bit HDRI export on higher tiers
  • Direct paths into Unity, Unreal and Blender plus Quest, Vision Pro and AndroidXR
  • Full API with custom rate limits on the Business tier
  • Commercial licensing and stated IP ownership on all paid plans

Cons

  • Credit caps of 100 to 500 a month make iteration expensive
  • HDRI, 3D meshes and priority queue are gated behind the $48 tier
  • The free tier cannot export anything, only preview

Which one fits

Choose Leonardo.Ai if you need

  • Game and product teams that need consistent assets from a fine-tune they control
  • Anyone who wants generation, canvas editing and upscaling in one place
  • Developers who need image generation behind an API rather than a chat window
  • Users who want to train a model on their own reference set

Choose Skybox AI if you need

  • Filling a VR or Unity scene with a background and matching light in minutes
  • Previs, matte-painting bases and LED-volume backdrops
  • Indie and Roblox or Fortnite Creative builders without an environment artist
