Flux Kontext Dev vs Flux Kontext Dev Lora
Base Flux Kontext Dev against Flux Kontext Dev LoRA — when to add a custom brand or SKU LoRA weight to your product relighting workflow.
Every value below is read from the model catalog at generation time — price and which parameters each model exposes. 2 of the 13 spec rows differ between these two. “Not exposed” means the model has no API parameter for it — it does not mean the capability is absent. A model without a transparent-background switch can still produce a clean white background from a prompt; it just cannot hand you an alpha channel.

Which should I use for e-commerce image editing?
Whichever exposes the control you need — the table above is the honest answer. For bulk background cleanup, start on the cheaper model and only move up for the hero image. For packaging or label text, test both on one SKU and check the lettering at 100% zoom before you run the batch.
