Magnific — the flagship image engine
Magnific is ToolAcces's main built-in engine: image generation and upscaling, with a rendering style that prioritizes photo realism and fine detail accuracy. It's the right default choice for a visual meant for large format, or for revealing detail in an existing image without changing its composition.
Nano Banana — consistent guided editing
Nano Banana excels at one specific use case: modifying an element of a supplied image (swapping a background, adjusting one detail, merging two visuals) while keeping everything else identical. It's the tool to reach for when you're starting from an existing visual that needs a fix, rather than a blank page to fill.
Grok Images — fast prompt-based generation
Grok Images (powered by xAI) covers classic prompt-based image generation, with a fast iteration speed — useful for exploring several creative directions before locking in a visual to refine afterward in Magnific or Nano Banana.
Comparison by use case
| Need | Engine to open |
|---|---|
| Generate a visual from text | Grok Images or Magnific |
| Modify an element of an existing image | Nano Banana |
| Increase resolution / detail | Magnific |
| Quickly explore several variants | Grok Images |
How to chain them on the same project
An efficient workflow often combines all three: generate several quick variants with Grok Images, pick the best direction and refine it with Nano Banana (fixing an element, adjusting a detail), then run the final result through Magnific for upscaling before delivery. For the prompting method common to all three engines, see our guide how to write a good AI image prompt.
All included in a single subscription
All three engines are accessible from the same ToolAcces interface, with no separate account or card needed for each. To see how these three engines stack up against the rest of the market (ChatGPT Images, Midjourney, Flux, Reve), see our comparison what's the best AI image generator in 2026. And for what you can actually do with the visuals you produce, see can you use an AI-generated image for commercial purposes.
Frequently asked questions
No — all three are included in the same ToolAcces subscription and serve different needs. The right approach is to treat them as a toolbox: generate with one, edit with another, enhance with the third, depending on the stage of the project.
Magnific is generally the strongest on this front, especially for upscaling, which reveals fine detail without changing the original composition.
Nano Banana is the best fit for guided editing — changing one specific element while keeping the rest of the image identical, which is more reliable than a full regeneration for this use case.
