Flux, Nano Banana Pro, Seedream, Recraft V4, and Imagen 4 in active production. Each model owns a task class. The routing layer decides which model runs — no single model handles every brief.
BFL (Black Forest Labs)
Routing rule
Photoreal characters, editorial work, hex-accurate brand color renders.
Cost note
Mid-range — quality justifies cost for hero assets.
Gemini 3.1 Flash Image
Routing rule
Multi-character lifestyle, food, product-in-scene, UI mockup contexts.
Cost note
Strong cost-quality ratio for complex multi-subject scenes.
ByteDance
Routing rule
Typography, packaging, abstract texture batches. Cheapest top-tier at 2K ($0.03/image).
Cost note
$0.03 at 2K — lowest cost per high-quality asset in the stack.
Recraft (V4 only — V3 permanently retired)
Routing rule
All vector, illustration, icon, pattern, and infographic work. Never photoreal.
Cost note
Pro tier $0.25/image. Worth it — only model with true vector.
Google (Fast / Standard / Ultra tiers)
Routing rule
Nature, aerial, corporate headshots, film-stock aesthetic briefs.
Cost note
Three tiers — Fast for iteration, Ultra for final hero assets.
