“Nude sheer pink-beige base · thin white micro French tip · soft square · glossy”
All six render clean, realistic nails — the difference is French definition, not quality. flux/imagen give a bolder, clearly-defined tip; OpenAI a subtler, very natural one. gpt-image-2 low is the cheapest ($0.0095) and genuinely clean — a strong pick if you like the natural look.

Not tested (no API key): Stability and Gemini. Times are single-call (Replicate = server predict_time). Cost figures are list prices; OpenAI low is measured from logs. All used preserve-bg ON so the background is identical — only the nails differ.
