The Best AI Image Models in 2026, Compared

There have never been more good text-to-image models — and never been more confusion about which one to use. This is a practical, no-hype comparison of the image models you can run on Yix, with a simple rule of thumb for each.

The short answer

• Want the best all-round quality? Use Nano Banana 2 or, for the absolute top tier, Nano Banana Pro.
• Comparing everyday image options? Use FLUX.2 Pro or Seedream 5 Lite.
• Want a lower-cost option for iteration? Use Grok Imagine or Seedream 5 Lite.
• Need readable text in the image? Use Ideogram V3 Turbo or GPT Image 2.
• Need maximum photorealism? Use Imagen 4 Ultra or Nano Banana Pro.

The models

Nano Banana 2 & Pro (Google)

Google's Nano Banana line is the current quality benchmark. Nano Banana 2 renders crisp detail and legible in-image text and is a great default. Nano Banana Pro pushes composition and 4K fidelity further — reach for it when the image is the hero.

FLUX.2 Max, Pro & Flex (Black Forest Labs)

The FLUX.2 family is prized for prompt adherence and typography. FLUX.2 Pro is the everyday workhorse; FLUX.2 Max is the top-quality tier; FLUX.2 Flex trades a little predictability for more creative control. All support 1–4 megapixel output.

Seedream 5 Pro & 5 Lite (ByteDance)

Seedream 5 Pro supports 1K or 2K generation and editing with up to 10 reference images. Seedream 5 Lite supports 2K or 3K and up to 14 references. Pro costs 30 credits at 1K and 70 at 2K; Lite costs 30 credits at either resolution. See the Seedream editing guide for a practical workflow.

GPT Image 2 (OpenAI)

GPT Image 2 is the best at following long, detailed instructions and rendering text — ideal for posters, infographics and cards. Pick Low / Medium / High quality to trade cost for fidelity.

Grok Imagine (xAI)

Grok Imagine is the speed-and-price champion. It's the cheapest way to iterate on an idea before committing credits to a flagship model.

Imagen 4 Ultra (Google)

Imagen 4 Ultra is Google's highest-fidelity Imagen model — exceptional photorealism, lighting and prompt adherence up to 2K. Reach for it when you need a convincing photograph rather than an illustration.

WAN 2.7 (Alibaba)

WAN 2.7 is Alibaba's text-to-image model: sharp, detailed output with solid prompt following at a very low price, up to 2K. A strong budget pick for everyday images.

Ideogram V3 Turbo (Ideogram)

Ideogram V3 Turbo is the best in the lineup at rendering readable in-image text and typography — fast and cheap, ideal for posters, logos and layouts.

How pricing works on Yix

Every image costs credits based on the model and resolution you choose — you always see the exact cost before you generate. New accounts get 100 free credits, which is enough to try a flagship model once or run several images on the faster ones. See the full breakdown on the pricing page.

Try them side by side

The fastest way to pick is to run the same prompt through two or three models and compare. That's exactly what Yix is for — open the generator and switch models with one click.
