Nano Banana 2 vs Pro: Real 2K Tests, Timing & Credits

We compared Nano Banana 2 and Nano Banana Pro on three matched image prompts. For a budget-first starting point, Nano Banana 2 is the practical pick in this small sample: it used 15 credits per image versus Pro's 25, while meeting the main product-photo and portrait requirements we checked. Pro's clearest advantage was the flatter poster layout. These six images do not show a consistent overall quality winner, and the timings do not establish a general speed winner.

Run summary

These are actual wallet debits for text-only 2K, 1:1 images, tested on October 27, 2026. Time is the provider job's recorded completion minus creation time, including its queue and processing.

Poster

Both rendered all three requested lines correctly with no extra words. Nano Banana 2 added a grey surround and shadow despite the no-border instruction. Pro was flatter and closer to a ready-to-use poster, though its cup was icon-like.

Shared prompt

A square minimalist coffee shop poster. Ivory background, forest-green serif typography. Render exactly these three lines, each once: MORNING CLUB / Fresh coffee, slow mornings / OPEN 7 AM. One small ceramic coffee cup below the text. No other words, logos, border or watermark.

Product photo

Both showed one amber bottle with the correct VIRVY label, a leaf on the left, and an orange slice on the right. Nano Banana 2's orange looked fresher and brighter; Pro's looked dried. The NB2 orange reached the frame edge. Both met the main object and label requirements.

Shared prompt

Studio product photograph of one amber glass perfume bottle with a matte black cap, centered on pale beige stone. The bottle label reads exactly VIRVY and nothing else. A single green leaf lies to the left, one round orange slice to the right. Soft window light from camera left, realistic glass reflections, sharp readable label, square composition. No other objects, text, watermark or collage.

Portrait

Both showed the requested person, clothing, book, lighting, and two visible hands with plausible anatomy. The book obscured some digits, so we could not verify five fingers on each hand.

Shared prompt

Editorial studio portrait of a fictional adult woman aged about 30 with short curly dark hair, natural skin texture and a navy linen shirt. Waist-up, both hands visible holding one closed red book. Hard rim light from camera left, soft fill from the front, neutral grey backdrop. Exactly five fingers per visible hand, realistic proportions, square composition. No text, jewellery, watermark or film border.

Method and limits

We submitted the six runs sequentially, with one output per model for each scene, no reference images, no rerolls, and no shared seed exposed by the interface. We reviewed each returned original once; the visual notes are qualitative observations, not benchmark scores.

Timings use each successful provider job's recorded creation and completion timestamps. They include upstream queueing and generation, not only model inference. Browser polling sometimes observed a result much later than the provider job had completed, so we use the provider job times consistently. Pro's poster and product jobs finished sooner in this sample; Nano Banana 2's portrait job finished sooner. One output per prompt is not enough to establish a general speed winner.

All six tasks succeeded. At the displayed prices, Nano Banana 2 used 15 credits per image and Pro used 25. The same internal test account's gift-credit wallet fell from 215 to 95 credits, a total debit of 120 credits; each task's actual debit matched its displayed price.

Which should you try?

Start with Nano Banana 2 if credit use matters and you want to test the result on your own prompt. In these samples it met the main product and portrait requirements at 15 credits per image. Try Nano Banana Pro when a specific layout, such as the flatter poster in this pair, matters to your work. That single poster example does not establish a general Pro advantage.

FAQs

Which model used fewer credits? Nano Banana 2 used 15 credits per image, compared with 25 for Pro, or 40% fewer relative to Pro's displayed price.

Which model was faster? Job timestamps show Pro finishing sooner on the poster and product jobs, while Nano Banana 2 finished sooner on the portrait. The times include upstream queueing and generation, and one run per prompt cannot establish a general speed ranking.

Did either model win on image quality? Not consistently in these three scenes. Pro matched the requested flat poster layout more closely; both models met the main product-photo requirements, and both portraits looked plausible at review size. Some fingers were hidden by the book, so exact finger counts remain unverified.
