Best AI Image Generators in 2026
AI image generation has exploded in 2026. With dozens of models and apps competing, it's hard to know which actually produces the best results. We tested the most popular options to help you decide.
Whether you need photorealistic portraits, creative art, product mockups, or social media content — there's an AI generator for you. Here's our honest breakdown.
What Makes a Good AI Image Generator?
The best AI image generators excel at photorealism (do images look real?), prompt adherence (does it generate what you asked for?), speed (how long does it take?), and ease of use (can anyone use it without prompt engineering?).
We also considered price, free tiers, and whether the tool works on mobile — because most people want to generate images on their phone, not at a desktop.
Nano Banana 2 (Used in Gluely)
Nano Banana 2 is the newest model on this list and one of the most impressive. It produces photorealistic images with exceptional skin texture, natural lighting, and accurate facial features. It's the primary model behind Gluely's 76+ AI styles.
Strengths: Incredible photorealism, fast generation (under 10 seconds), excellent face preservation when using reference photos. It handles both text-to-image and image-to-image editing through its companion model Nano Banana Edit.
Available through Gluely on iOS with free credits to start. No prompt engineering needed — just pick a style and upload your photo.
Flux (Schnell, Dev, Pro)
The Flux family from Black Forest Labs offers three tiers. Flux Schnell is the fastest (under 2 seconds) and cheapest, great for quick iterations. Flux Dev balances quality and speed. Flux Pro produces the highest quality but takes longer.
Strengths: Excellent text rendering in images, strong artistic styles, fast generation. Weaknesses: Less consistent with photorealistic faces compared to Nano Banana 2.
Ideogram V3 & Recraft V3
Ideogram V3 excels at text-in-image generation — if you need AI-generated images with readable text (logos, posters, signage), it's the best option. Recraft V3 focuses on design-oriented outputs with strong composition.
Both are available through Gluely alongside other models, giving you the flexibility to try different generators for different use cases.
Our Recommendation
For photorealistic images (selfies, portraits, characters), Nano Banana 2 through Gluely is our top pick. The combination of quality, speed, and the style-based interface (no prompt writing needed) makes it the most accessible option.
For creative art and text-in-image, try Flux or Ideogram. The good news? Gluely gives you access to multiple models in one app, so you can try them all with free credits.
