Best AI Image Generators in 2026: Nano Banana Pro vs GPT Image 2 vs Seedream 5 Pro vs FLUX 3
The four leading AI image models compared on what matters: text in images, editing with reference photos, 4K output, aspect ratios and cost per image. Plus the best pick for posters, product shots and illustrations.
By Opeek5 min read
Short answer: the best AI image generator in 2026 depends on the job:
- Nano Banana Pro (Google) is the best all-rounder: detailed scenes, precise prompt following, legible text, 4K, and edits that combine many reference images.
- GPT Image 2 (OpenAI) is the best value and the best at long, complex prompts. It's 9 coins an image.
- Seedream 5 Pro (ByteDance) is best for high-resolution layouts with text in many languages.
- FLUX 3 (Black Forest Labs) is best for photorealism up to 4K.
- For posters and logos, use Ideogram 4.5. For vector-style design assets, use Recraft V4.1.
All of them run on inker with one coin balance and no subscription.

| Model | Made by | Best for | Max resolution | Images per run | Edit with references | Coins per image on inker |
|---|---|---|---|---|---|---|
| Nano Banana Pro | All-round quality, text in images | 4K | 1–4 | Yes, many images | 26 | |
| Nano Banana 2.1 | Sharp 4K images with clean text | 4K | 1–4 | Yes | 21 | |
| GPT Image 2 | OpenAI | Long, complex prompts, placing objects | 2K | 1–4 | Yes, up to 16 | 9 |
| GPT Image 2.5 Sunburst | OpenAI | Intricate detail, many rounds of edits | 2K | 1–4 | Yes, up to 16 | 9 |
| Seedream 5 Pro | ByteDance | Layouts, text in many languages | 2K | 1–4 | Yes, up to 10 | 24 |
| FLUX 3 | Black Forest Labs | Photorealism, accurate text | 4K | 1 | Yes | 18 |
| Ideogram 4.5 | Ideogram | Posters, logos, typography | 2K | 1–4 | One source image | 11 |
| Recraft V4.1 | Recraft | Illustrations, design assets, mockups | 1K (Pro: 2K) | 1 | No | 6 (Pro: 36) |
| Nano Banana 2 | Fast everyday images | 4K | 1–4 | No | 11 |
Coin prices are for one image at inker's default settings (2K where offered) at the time of writing. Resolution and the number of images change the price, and the studio always shows the exact cost first. In the €5 starter pack, 1 coin = €0.01, so a GPT Image 2 picture costs about €0.09.
Nano Banana Pro: the best all-round AI image generator
Google's Nano Banana Pro is the model to start with when you're not sure. It follows detailed prompts closely, renders clean, readable text inside images, and goes up to 4K in every aspect ratio from 21:9 to 9:16. Its edit mode is the strongest reason to pick it: describe a change in words and it updates your picture while keeping the rest intact. It can also combine several reference images, for example a product, a model and a location, into one scene.
Watch out for: the price. At 26 coins it's one of the more expensive models. For drafts, Nano Banana 2 (11 coins) uses the same prompt style. See our Nano Banana prompt guide.
GPT Image 2: best value and best for complex prompts
OpenAI's GPT Image 2 is good at reading long, detailed instructions, like "a flat-lay with a red notebook top-left, a coffee cup bottom-right and the words 'Monday plan' on the notebook". It puts things where you describe them. At 9 coins it is also one of the cheapest premium models, and its edit mode takes up to 16 reference images.
The newer GPT Image 2.5 comes in two flavours at the same price. Flare is fast, with natural lighting and rich textures. Sunburst takes longer but adds fidelity in intricate detail, and keeps the subject stable over many rounds of edits.
Watch out for: no seed and no 4K by default. If you need to recreate an exact result or print large, use Nano Banana Pro or FLUX 3.
Seedream 5 Pro: best for layouts and multilingual text
ByteDance's Seedream 5 Pro is built for detailed, high-resolution images with precise layouts and clean text in many languages. That makes it a strong choice for menus, infographics, packaging and social graphics in Spanish, French or Arabic. Its edit mode changes one element precisely and takes up to 10 reference images.
Budget option: Seedream 5 Flash costs just 5 coins an image.
FLUX 3: best for photorealism up to 4K
Black Forest Labs' FLUX 3 is the pick for images that should look like photographs: skin, fabric, food and products in realistic light. It also renders accurate text, goes up to 4K, and supports every common aspect ratio. Its edit mode changes elements, styles or text from a description and works with reference images. For the highest quality FLUX.2 output, FLUX.2 Max (28 coins) adds rich detail and realistic lighting, but in fewer aspect ratios.
Watch out for: FLUX 3 makes one image per run, so comparing variations takes several generations.
Best for posters, logos and design work
- Ideogram 4.5 (11 coins) is made for posters, logos and graphics where the text has to be spelled right and placed well. Here is the poster its predecessor, Ideogram 4, made in our pay-as-you-go test, unedited:
- Recraft V4.1 (6 coins) makes polished illustrations, design assets and product mockups. Recraft V4.1 Pro renders the same style at 2K for print.
- Qwen Image 3 Pro (11 coins) from Alibaba is a solid choice for detailed images with accurate text, and supports a negative prompt.
