Flux Kontext genera imágenes IA en ~5 segundos con consistencia de estilo superior. Ideal para edición contextual y consistencia de personajes.
Flux Kontext es un generador de imágenes IA de Black Forest Labs que combina una generación ultrarrápida (~5 segundos) con edición contextual avanzada. A diferencia de los modelos tradicionales, Flux Kontext te permite editar imágenes existentes en lenguaje natural manteniendo la consistencia visual — ideal para diseños de personajes, campañas de marca y producción creativa a escala.
10 credits per image (Pro) · 15 credits per image (Max)
Flux Pro at 10 credits (~$0.10) per image is the sweet spot for speed and quality — you get a stunning image in 5 seconds for a dime. Flux Max at 15 credits costs a bit more but delivers higher detail. Compared to Midjourney ($10–30/month subscription with generation limits), pay-per-image gives you more control over spending.
Flux Kontext is the best choice when you need the fastest possible generation with excellent aesthetic quality. At ~5 seconds for Flux Pro, it's the quickest way to go from idea to image. The character consistency feature is genuinely unique — create a character once and maintain their exact appearance across 50+ different images, perfect for brand mascots, campaign characters, and visual series. The 2048px maximum resolution also makes Flux the only realistic choice for print and large-format output. Designers and artists particularly love its natural aesthetic quality.
If you need perfect text rendering in images — posters with readable headlines, meme text, infographics — GPT Image 1 is significantly better at text accuracy. If you need the cheapest possible image generation, Seedream at 5 credits/image is half the price of Flux Pro. For portrait-heavy content targeting Asian markets, Seedream has better cultural aesthetic understanding. And for complex, multi-step editing instructions, GPT Image 1's deeper language understanding (built on GPT-4o) handles nuanced requests better.

Unlike some models that need elaborate descriptions, Flux responds beautifully to concise prompts. Focus on the key visual — subject, mood, lighting.
Generate a base image, then upload it back with specific change instructions. 'Make the background darker', 'Add a hat', 'Change season to winter'. This gives you precise control.
Flux understands camera and photography language well. Use terms like 'f/1.4', '85mm lens', 'studio lighting', 'golden hour' for photorealistic results.
