Other models on Upsampler that cover similar ground.
Flux 2 Pro
Black Forest Labs' Flux 2 production tier — the current Flux flagship for most use cases. Stylized photorealism with stronger prompt adherence than Flux 1.1 Pro, broad aesthetic range, and reference-image support. Sits below Flux 2 Max on top-end fidelity but offers a better cost-quality ratio for production work.
Flux Kontext Pro
Black Forest Labs' instruction-based image editor — describe an edit in plain English ('replace the background with a sunset beach', 'change the shirt to red') and get a clean result that preserves the rest of the scene. Strong identity and lighting consistency makes it production-ready for outfit swaps, background replacement, and prop changes.
Flux Schnell
Black Forest Labs' fastest, lowest-cost Flux variant. Built for rapid prototyping, moodboards, and high-volume batch generation where speed and credit cost matter more than raw fidelity. Open-weight and well-supported in the community, with extensive prompt-pattern documentation accumulated since the original Flux release.
Ideogram V3
Ideogram V3 in edit mode. Typography-aware revisions for design-focused workflows — logo refinements, packaging text edits, poster typography revisions. Cheaper than GPT Image 2 for typography-heavy editing, though weaker on general photo edits where instruction-following matters more than text rendering.
