About

FLUX.1 Kontext [dev] is built for instruction-based editing: give it a source image and a sentence, and it changes what you asked for while preserving identity, layout, and lighting.

It accepts up to two reference images. For heavier multi-reference editing, compare with Qwen Image Edit 2511 (three references) and GPT Image 2 (sixteen). Requires Premium Spark.

Pricing

On the Sogni API you pay per render in Spark (1 Spark = $0.005). Prefer a flat rate? The Sogni app runs FLUX.1 Kontext [dev] and 100+ other models credit-free under fair use.
