Grok Imagine 2 and Nano Banana 2 are both live in Picsart AI Playground, and they are built for different halves of the job. Grok Imagine 2 makes one precise frame from one instruction. Nano Banana 2 assembles a frame out of many inputs and can go looking for real-world reference before it renders. The fastest way to choose is to count how many images you need to feed it.

The difference that decides it: one reference image or fourteen

Grok Imagine 2 accepts a single reference image per generation. You give it one picture, describe the change, and it applies the edit while preserving what you did not mention. That is a clean loop for refining one subject.

Nano Banana 2 accepts up to 14 reference images in one generation. Within that budget it holds high fidelity on up to 10 objects and keeps up to 4 characters consistent. That is a different kind of work: putting a specific product, a specific person, and a specific setting into one frame without compositing them by hand.

Everything else between these two models follows from that split. One is a precision instrument for a single frame. The other is an assembly tool for scenes with many fixed ingredients.

Where Nano Banana 2 pulls ahead

It composes from many inputs. Fourteen reference images is the headline number, and the useful part is the breakdown: 10 objects rendered with high fidelity, 4 characters kept recognizable. A campaign frame with two models, a product, and a location becomes one generation instead of a layered file.

It reaches 4K, and drops to 512px. The ceiling matters for print and large-format work. The floor matters more than people expect: a 512px pass is the cheapest way to test twenty compositions before committing to one.

It can look things up. Nano Banana 2 draws on web and image search results, so a prompt can lean on real places, real objects, and current information rather than the model’s memory of them. Ask for a specific landmark or a specific species and the reference is fetched rather than approximated.

It writes text in other languages. Beyond rendering legible type, the model handles translation inside the image, so the same layout can ship in several languages without a separate design pass for each.

It thinks before it renders. On complex, multi-part prompts the model works through the composition first, which is why long instructions with several simultaneous requirements hold together more often.

Where Grok Imagine 2 pulls ahead

You set the quality tier yourself. Resolution runs 1k or 2k and quality runs Low or Medium, which gives four explicit combinations from one prompt. Drafting at the low end and finishing at the high end is a decision you make, not one the model makes for you.

It preserves the input tightly. With a single reference and a clear instruction, Grok Imagine 2 changes what you named and leaves the rest alone. Fewer inputs means fewer things the model can decide to reinterpret.

It covers phone-screen frames. Grok Imagine 2 offers 19.5:9, 9:19.5, 20:9, and 9:20, which match real device proportions, plus 2:1 and 1:2 for wide banners and tall units. Nano Banana 2 does not have those four.

It plans layout and typography together. Dense visuals with a headline and fine print hold their structure, which makes it a strong pick for posters and title cards where the type is the design.

The frames each one can fill

The two ratio sets overlap less than you would guess. Seven ratios are common to both: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2, and 2:3. That covers most everyday placements, and for those the choice comes down to capability rather than shape.

Past the overlap they diverge completely. Grok Imagine 2 adds 2:1, 1:2, 19.5:9, 9:19.5, 20:9, and 9:20, so full-bleed phone screens and wide web banners are native. Nano Banana 2 adds 4:5, 5:4, 21:9, 4:1, 1:4, 8:1, and 1:8, so cinematic widescreen and extreme strips are native. An 8:1 frame is a header that runs the full width of a page. A 1:8 frame is a tall vertical stripe.

If the placement is a phone screen, one model already fits it. If the placement is a panoramic banner, the other does. Neither can be talked into a ratio it does not have.

Pick by the job in front of you

  • One subject, one clean edit. Grok Imagine 2. A single reference and a named change is exactly its loop.
  • A product, a person, and a place in one frame. Nano Banana 2. This is what 14 references are for.
  • A poster or title card where the type carries the design. Either one handles text well, so pick on frame: Grok Imagine 2 for phone and banner shapes, Nano Banana 2 for widescreen and strips.
  • The same layout in five languages. Nano Banana 2, for in-image translation.
  • Print or large-format output. Nano Banana 2, for the 4K ceiling.
  • Budget-controlled drafting. Grok Imagine 2, where you set the quality tier deliberately.
  • Anything that has to match a real place or object. Nano Banana 2, for search grounding.
  • A character kept consistent across a set. Nano Banana 2, which holds up to four.

Try both on the same prompt

The honest test is one prompt, both models, same frame. Run this one at 16:9 in each and compare how the type and the light land.

Same-prompt test, both models

Editorial poster for a coastal film festival, hand-painted mid-century style, deep teal and warm sand palette, bold display headline reading NORTH SHORE across the upper third, a single line of small text along the bottom edge reading FILM FESTIVAL, layered flat shapes, printed paper texture, sharp legible lettering, late-afternoon light raking from the left

Then run a prompt only one of them can take, to see what the reference budget buys.

Multi-reference composite, Nano Banana 2

Place the product from the first image on the table in the second image, with the person from the third image seated behind it. Keep the product label, the table surface, and the person’s face exactly as they appear in the source images. Match the lighting to the second image, warm window light from the left, soft shadow to the right. Editorial lifestyle photography, natural color, shallow depth of field

Where each model lives in Picsart

Both models sit in Picsart AI Playground, so you can switch between them without leaving the prompt box. That is the cheapest way to settle a comparison: same prompt, two models, side by side.

For background on either one, the Grok Imagine model page and the Nano Banana 2 model page cover the families they belong to. The AI image generator runs on a broad model set, and the full image models lineup shows what else is available for a given job.

Neither is better across the board. Grok Imagine 2 is the stronger choice when you are refining one frame from one reference image and want to set the quality tier yourself. Nano Banana 2 is the stronger choice when a frame has to combine several fixed inputs, reach 4K, or draw on real-world reference.
