Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Comet ML
- The free cloud tier caps data at 25,000 spans a month with 60 day retention
- Retention stays at 60 days even on the paid Pro plan, and extending it is a $29 per 100k spans add on
- Overage on Pro is $5 per additional 100,000 spans
- The free MLOps tier is a single user with 100 GB of storage and training hours governed by a fair usage policy
- Pro MLOps is $19 per user per month and caps the team at 10 users
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

Answered from the vendors’ own pages
Leonardo AI: Does Leonardo AI grant commercial rights to generated images?
Yes. All Leonardo AI plans grant full ownership and unrestricted commercial rights to generated images, allowing creators to sell AI-generated art and use outputs in commercial products.
SourceLeonardo AI: How does Leonardo's Real-Time Canvas work?
The Real-Time Canvas is a freeform workspace where images generate as you draw, type prompts, or add elements, updating the output approximately every 2 seconds per stroke, supporting inpainting, outpainting, and composite editing.
SourceLeonardo AI: What models does Leonardo AI offer beyond its own?
Leonardo API supports both in-house models (Phoenix, Lucid Origin, Lucid Realism) and third-party models including FLUX.1, Ideogram 3.0, GPT Image, Kling, Veo, and others under a unified pay-as-you-go API surface.
SourceLeonardo AI: What is included in the free tier?
The free plan provides 150 tokens per day enabling hundreds of images per month, but outputs are non-commercial only; paid plans starting at $12/month unlock commercial rights and higher token allocations.
