The best AI for image generation in 2026
Which AI is best for image generation depends on the job: drafting, following a literal brief, rendering the finished image, or editing a picture you already have. This guide matches each job to a model. Every model below is on the $23/month Pro plan and up; on the $11 Basic plan, the only image model is GPT-5 Image Mini.
No image model wins every job, so pick by task: drafts on GPT-5 Image Mini, the cheapest image model here; literal briefs with counts or short labels on Flux 2 Pro; high-quality finals on GPT Image 2.5 Flare; edits to an existing picture on Nano Banana 2. All four are on Pro ($23/mo) and up.

How to do it in TulexAI
- 1
Draft compositions cheaply
Rough out a few layouts from one prompt on the cheapest image render on the plan, changing one clause per re-render until the framing works. · GPT-5 Image Mini
- 2
Hit a literal brief
When the brief names an object count, a layout or a short label, give each instruction its own clause and run a few variants to pick from. · Flux 2 Pro
- 3
Render the finished image
Take the settled prompt to a high-quality render for the final asset, choosing square, landscape or portrait before you generate. · GPT Image 2.5 Flare
- 4
Edit an existing image
Save the render and attach it, or attach a photo of your own, say what must stay the same, then describe the change, such as a new background or a removed object, instead of re-rolling the prompt. · Nano Banana 2

Frequently asked questions
It depends on the job: GPT-5 Image Mini for cheap drafts, Flux 2 Pro for literal briefs, GPT Image 2.5 Flare for finished renders and Nano Banana 2 for edits to an existing image. All four are on the $23/month Pro plan and up; on the $11 Basic plan, the only image model is GPT-5 Image Mini.
We have no independent benchmark that ranks them, so we do not claim one. Both are OpenAI models at the same PT price per image here. Flare is the newer model, which OpenAI describes as fast, high-quality everyday image generation. TulexAI runs Flare at its high setting and GPT Image 2 at its medium setting, which OpenAI bills at the same number of output tokens for a square image. Stay on GPT Image 2 when a prompt is already tuned to its look; otherwise run one prompt on both and keep the one that reads your brief better.
Flux 2 Pro and GPT Image 2.5 Flare are good first tries for short text, such as a headline, a sign or a label. Give the words their own sentence in the prompt, run that prompt through both to see which spells it right, and add paragraph-length copy in a design tool afterwards.
Yes. Attach the image and describe the change in words, leading with what must stay the same; you write an instruction rather than painting a mask. Nano Banana 2 and GPT Image 2.5 Flare both edit an attached photo. On Flare, an edit with several reference images or a very long prompt counts as more than one image, in line with what OpenAI bills.
