Both ChatGPT and Gemini can now edit your photos from a plain text instruction. Neither is better at everything — and picking the wrong one for a given job is the single most common reason people get a mangled, over-processed result.
We ran both on the same set of editing tasks. Here is the honest breakdown of which model wins where.
Short on time? ChatGPT (GPT Image 2) wins on complex multi-step instructions and text inside images. Gemini (Nano Banana 2) wins on identity preservation, old photo restoration, and speed — and it is free.

The models you are actually comparing
This matters more than most comparisons admit, because both products renamed their underlying models in 2026:
If a guide still tells you to use "Gemini 2.5 Flash Image" or "DALL-E 3", it predates both of these and its advice on model behaviour is out of date.

Head-to-head: which model wins each task
| Editing task | Winner | Why | | --- | --- | --- | | Keeping a face identical | Gemini | Nano Banana 2 holds facial identity noticeably better across edits. Critical for saree, retro and portrait trends. | | Restoring old / damaged photos | Gemini | Stronger at reconstructing missing detail and colourising without inventing new faces. | | Complex multi-step instructions | ChatGPT | Follows long, layered prompts ("do A, but preserve B, and also C") more reliably. | | Text inside the image | ChatGPT | GPT Image 2 renders legible, correctly spelled text far more consistently. | | Background removal / swap | Tie | Both produce clean cutouts. Gemini is faster; ChatGPT blends edge lighting slightly better. | | Product / commercial shots | ChatGPT | Better at neutral colour accuracy and clean commercial finish. | | Speed and cost | Gemini | Free in the Gemini app, and noticeably faster per edit. | | Iterating on one image | Gemini | Multi-turn editing holds context well without drifting. |

When to use Gemini
Reach for Gemini when the photo contains a real person whose face must stay recognisable. This is the single clearest gap between the two. Identity-preserving edits — the saree trend, retro portraits, wedding edits, "meet your younger self" — are where Nano Banana 2 is meaningfully ahead, and where ChatGPT tends to subtly redraw the face.
It is also the better choice for restoring old family photos, and it is free, which matters if you are iterating a lot.

When to use ChatGPT
Reach for ChatGPT when the edit is complicated rather than personal. If your instruction has several conditions stacked together, or the image needs legible text in it — a product label, a poster title, a banner — GPT Image 2 is the more reliable model.
It is also the stronger option for commercial and product work, where accurate colour matters more than facial identity.

The same edit, both models
To show the difference concretely, here is one instruction and how each model handles it.
The task: turn a casual phone photo into a professional headshot.
"Convert this photo into a professional corporate headshot. Replace the background with a softly blurred neutral grey backdrop. Apply flattering Rembrandt lighting from the front-left. Change the clothing to a navy blazer over a white shirt. Keep the face 100% identical — same features, same expression, natural skin texture. Photorealistic."
Gemini (Nano Banana 2) holds the face almost exactly and produces a usable result in one pass. Occasionally softens the blazer detail.
ChatGPT (GPT Image 2) produces a cleaner, more polished blazer and background, but is more likely to subtly restructure the face — worth a second pass with "do not change any facial features" if identity matters.
The takeaway: if it is going on your LinkedIn and it needs to look like you, start with Gemini. If it needs to look like a magazine, start with ChatGPT.

Prompt patterns that work in both
Whichever model you pick, these three habits change results more than the model choice does.
1. State what must NOT change
This is the highest-leverage line in any editing prompt. "Keep the face 100% identical — same features, same skin tone, no beautification" prevents the most common failure in both models.
2. Be specific about the genre and the lighting
Tell the model what kind of photo it is (macro, candid street, commercial product) and how it should be lit. Both models default to making things too bright and too smooth. Terms like 'soft diffused lighting', 'Rembrandt lighting' or 'harsh dramatic shadows' give you control back.
3. Iterate one change at a time
Do not ask for ten changes in a single prompt. Fix the lighting first. Once that is right, ask for the colour grade. Then the sharpening. Gemini in particular holds context well across turns, so iterating costs you nothing.
