Leonardo AI
Pros
- + One token wallet spans Leonardo's Phoenix plus licensed FLUX, Veo, Kling, Ideogram and GPT Image models — I compared four models in one session without switching tools
- + Character Reference held face identity across outfit and background changes in my testing
- + Free tier of 150 tokens/day is enough for real evaluation, not just a demo
- + Artisan (US$30/month, 25,000 tokens) covers a few thousand polished images a month at typical token costs
- + Canva ownership means balance-sheet backing and continued investment in the stand-alone product
Cons
- - Token costs vary per model and feature with no simple rate card; free-tier budget drains within one serious session
- - App subscriptions do not include API access — the Production API is a separate pay-as-you-go wallet
- - The early-2026 Canva restructure folded engineering into Canva core; roadmap control now sits with the parent
- - Per-image aesthetic quality trails Midjourney and prompt adherence trails FLUX in my testing
- - Features land fast and sometimes feel half-integrated, especially in video
Flux by Black Forest Labs
Pros
- + FLUX.2 [max] honored a layout sketch, product shot and palette reference simultaneously — the strongest multi-reference control I tested
- + Prompt adherence on long, object-heavy prompts leads the category in my experience
- + Real per-image economics: FLUX 3 Image at US$0.048/image, FLUX.1 [dev] at US$0.025 on BFL's own API
- + Open-weight [dev] and [klein] models with fine-tuning and LoRA rights on paid license tiers
- + Founder pedigree (the latent diffusion authors) plus a US$3.25B valuation and deployments across Adobe, Canva and Leonardo
Cons
- - No first-party consumer UI — real usage happens through third-party wrappers of varying quality
- - Open weights cannot be deployed commercially without a paid BFL license tier (Builder and up)
- - Per-megapixel billing rounds resolution up, and ten reference images on [max] add US$0.30 before generation
- - Long passages of in-image text still garble about a word in eight; Ideogram is materially better for text
- - Model releases run fast (FLUX.1, FLUX.2, FLUX 3 in under two years) — integrations need version pinning
