Line-by-line comparison
Strengths and weaknesses
Leonardo AI
- Most generous free tier of the big three: 150 tokens per day (roughly 30-75 images depending on model), with the flagship Lucid Origin available to free users
- Lucid Origin (Aug 2025) renders native Full HD with strong prompt adherence and a consistent aesthetic across a series, ideal for characters and brand sets
- Deepest toolbox in this lot: canvas editor, inpainting, Universal Upscaler, 3D texture generation and custom model training on your own images
- Token bank rollover on paid plans (up to 3x the monthly allowance) softens the use-it-or-lose-it problem; Premium adds unlimited relaxed generations on select models
- Canva backing since July 2024: shared infrastructure, faster model cadence and Veo 3 video generation built in
- Developer API with token-based pricing, plus Lucid Origin distributed on Replicate and other inference platforms
- Opaque token economics: premium models, high resolutions and variations multiply costs, and users report the free 150 tokens gone in about 10 generations on top models
- Interface overwhelms beginners: dozens of models, modes and sliders before your first good image; documented complaint that advanced tools are not beginner-friendly
- Output quality is inconsistent across the community model library; results depend heavily on picking the right model
- Video is a costly add-on: premium third-party video models are billed on top (around $3.50 per premium video generation reported)
- Free plan creations are public with basic quality settings, and commercial rights require a paid plan
Google Nano Banana (Gemini Image)
- Real free tier: about 20 images per day with Nano Banana 2 in the Gemini app Basic tier, no card required
- Nano Banana Pro renders legible multi-line text and infographics up to 4K, among the best text engines alongside Reve
- Signature conversational editing and character consistency: iterate on the same subject across scenes in plain chat
- Cheap, granular API: Nano Banana 2 from about $0.045 per image, Pro at $0.134 (1K/2K) and $0.24 (4K), with a 50% Batch API discount
- Google AI Plus dropped to $4.99/month in June 2026 (up to 50 images/day plus 400 GB storage), the cheapest paid on-ramp of any major generator
- Visible Gemini sparkle watermark on free and Pro tier images; only AI Ultra and paid API/AI Studio outputs drop it, and the invisible SynthID watermark stays on everything
- Daily caps are dynamic and opaque: Google adjusts limits with capacity and states that free access is limited and can change
- No API free tier for the current image models (gemini-3.1-flash-image-preview and gemini-3-pro-image-preview)
- Quality crown lost in 2026: the Arena leaderboard ranks Nano Banana 2 below GPT Image 2 and Reve 2.0
- Watermark-free consumer use effectively costs $100 to $200/month since the AI Ultra restructuring at I/O 2026

The arena’s verdict on Leonardo AI
Pick Leonardo if you want one subscription covering generation, editing, upscaling, custom-trained models and video: no rival in this lot matches the breadth, and 150 free tokens a day is the most honest trial around. Game artists and creators producing consistent series get the most out of Lucid Origin. Avoid it if you hate metered systems, because the token math punishes heavy or careless use; for pure prompt-to-image value, Ideogram (design) or a self-hosted Stable Diffusion (control) deliver more per dollar.
The arena’s verdict on Google Nano Banana (Gemini Image)
For most people Nano Banana is the default choice: the Gemini app gives about 20 free images a day and $4.99/month buys up to 50 a day, nothing mainstream is cheaper. Move to Google AI Pro at $19.99/month if you need 100 Nano Banana Pro images daily for text-heavy or 4K work. Avoid it if you cannot live with the visible watermark below the $100/month Ultra tier, or if you need the absolute best output: GPT Image 2 leads the Arena and Reve 2.0 offers finer layout control. API developers get better per-image economics here than almost anywhere else.
What the crowd says
On Leonardo AI
“Tokens just evaporate. Switched to a premium model with upscaling on and my whole daily allowance was gone in 8 images.”
“150 free tokens a day is real. I prototyped an entire board game skin over two weeks without paying a cent.”
“Lucid Origin keeps my main character consistent across a 20-image set. Exactly what my game's concept art needed.”
On Google Nano Banana (Gemini Image)
“The sparkle watermark on a $20/month Pro plan is insulting. Not paying $100 for Ultra just to remove it.”
“Built an infographic pipeline on the API, $0.13 a pop at 2K and the labels are actually readable. Batch discount halves it.”
“20 free images a day in the Gemini app is unbeatable for casual use, and character consistency across edits is scary good.”
