Best AI Image Model in 2026: 18 Models Compared
Find the best AI image model for your project. Compare quality, speed, pricing, editing, and reference image support across 18 models from FLUX, Google, OpenAI, Seedream, Recraft, and Grok.
Choosing the best AI image model depends on what you need: photorealism, speed, editing capabilities, or budget. We tested all 18 models available on Melies and compared them across quality, generation speed, resolution, reference image support, and cost per image. Whether you need a quick draft or a production-ready 4K image, this guide helps you pick the right AI image generator.
The models span seven major providers: Black Forest Labs (FLUX family), Google (Nano Banana 2, Imagen 4 Fast), OpenAI (GPT Image 1.5), ByteDance (Seedream 4.5, Seedream 5 Lite), xAI (Grok Imagine), and Recraft (Recraft V4). Prices range from 2 credits for FLUX Schnell to 25 credits for FLUX.2 Max, with significant differences in output quality and features at each price point. Nine models support image editing, and seven accept reference images for character and brand consistency.
Every model in this comparison is available on Melies with shared credits. Switch between models with one click, generate the same prompt across multiple models, and compare outputs side by side. No separate subscriptions, no per-model billing.
