Both are flagship image models available on Lilidi AI with one shared credit balance. GPT Image 2 (OpenAI) is the safer pick for long structured prompts and crisp on image text; Nano Banana Pro (Google Gemini 3) is the pick for 4K detail and reference driven composition. Pick GPT Image 2: You write long, structured prompts with explicit layout instructions, or you need dependable text rendering on a poster or packaging mockup. Pick Nano Banana Pro: You need maximum resolution (up to 4K), you are composing from several reference images, or you want the widest set of native aspect ratios. Verdict: There is no single winner — they fail in different places. Because both run on the same Lilidi credit balance, the practical workflow is to draft with one and re run the same prompt on the other before committing to a final render. Provider: GPT Image 2 — OpenAI; Nano Banana Pro — Google DeepMind
(Gemini 3). Max quality tier in Lilidi: GPT Image 2 — 1K; Nano Banana Pro — 1K / 2K / 4K. Reference images: GPT Image 2 — Up to 6; Nano Banana Pro — Up to 6. Aspect ratios: GPT Image 2 — Renders 1:1, 3:2, 2:3 natively; other frames are cropped to the requested ratio; Nano Banana Pro — Native support for all 11 frames in the picker. Text on image: GPT Image 2 — Strong — posters, packaging, memes; Nano Banana Pro — Strong — signage, packaging, long headlines. Typical use: GPT Image 2 — Ad creative, storyboards, layout heavy prompts; Nano Banana Pro — Hero shots, 4K product and portrait work. Speed: GPT Image 2 — Moderate; Nano Banana Pro — Moderate; slower at 4K. Credit cost: GPT Image 2 — See the in app cost shown on the model card; Nano Banana Pro — See the in app cost shown on the model card. Q: Can I run the same prompt on both? A: Yes. Generate with one model, then switch the model in
the picker — the prompt and references stay in place. Q: Do I need two subscriptions? A: No. Lilidi AI is one account with one credit balance covering every model in the picker. Q: Which one renders text better? A: Both render legible text. GPT Image 2 is more consistent on dense paragraph text; Nano Banana Pro is stronger on large display type at high resolution.
