Flux and Nano Banana (Google's Gemini image model) are two of the strongest image models, and they lean in different directions — one for generating, one for editing.
Flux is exceptional at creating a photoreal image from a text prompt: lighting, materials, and composition from scratch. It's the default for a brand-new scene or hero image.
Nano Banana shines at editing an existing image and keeping subjects consistent across edits — swap a background, change an outfit, iterate on a product shot. Note it's conservative about named real people (route those to Grok).
Terminal X routes generation prompts to Flux and edit prompts to Nano Banana automatically, so you get the right one without knowing the difference.
| Task | Better pick |
|---|---|
| New photoreal scene from text | Flux |
| Editing an existing image | Nano Banana |
| Consistent characters across edits | Nano Banana |
| Named real people / celebrities | Neither — use Grok |
Flux for generating a new photoreal image, Nano Banana for editing and consistency. Terminal X routes each request to the right one automatically.
Or skip the comparison shopping: Terminal X routes one prompt to the right model automatically — and runs several in parallel when a job needs more than one.
