Model Comparison
A detailed side-by-side look at GPT Image 1.5 and FLUX.1 Kontext: features, quality, and the right use case for each.
OpenAI's Image Model — Perfect Text, Editing, and Multi-Object Scenes
GPT Image 1.5 is OpenAI's image generation model — the same model powering image creation in ChatGPT-4o. It excels at accurate text rendering inside images, image editing with mask-based inpainting, and complex multi-object scenes (10–20 distinct objects). Three quality levels (low/medium/high) let you balance speed and detail. Outputs in PNG, JPEG, or WebP with optional background transparency.
Natural Language Image Editing by Black Forest Labs
FLUX.1 Kontext by Black Forest Labs is an AI image editing model that transforms images through natural language instructions. Two tiers: [Pro] for ultra-fast editing (up to 8x faster than GPT-Image) and [Max] for maximum precision, better typography, and complex multi-step workflows. Non-destructive editing preserves the original image while applying targeted changes.
