Google's Nano Banana Pro narrows most of the gaps from the standard version. So how does it actually compare to GPT Image 2 today? Same hard-mode prompts, real outputs, side by side.
TL;DR Nano Banana Pro improves text rendering to roughly 94%, partially supports CJK, and editing fidelity is significantly better than the standard model. GPT Image 2 still leads on text (~99%), full multilingual coverage, and dense scenes with many small elements. The price gap also closes — Pro is now in the same ballpark as GPT Image 2. Decide by output type, not by cost.
Same Prompt, Side by Side (Hard Mode) These are the prompts that separate top-tier models. GPT Image 2 on the left, Nano Banana Pro on the right.
1. Movie poster with a long credit block A movie poster for a film called "THE LAST LIGHTHOUSE", credits at the bottom: "DIRECTED BY ANNA REED · STARRING MARK CHEN · IN THEATERS DEC 2026"
| GPT Image 2 | Nano Banana Pro |
|---|---| Long-string text: GPT Image 2 nails the entire credit block character-for-character. Nano Banana Pro gets the title right, but mangles two words in the credits — close, not perfect.
2. Bilingual chalk menu (English + Chinese) A bilingual coffee shop menu board: "COLD BREW $5" / "冷萃咖啡 ¥35", chalk style, top-down view
| GPT Image 2 | Nano Banana Pro |
|---|---| Mixed-script test: GPT Image 2 renders both English and Chinese cleanly. Nano Banana Pro now handles the Chinese — a clear improvement over the standard version — but the strokes still look slightly off. For brand-quality CJK output, GPT Image 2 still wins.
3. Dense infographic A complex infographic on "How Photosynthesis Works" with 6 labeled steps, arrows, plant illustration in the center
| GPT Image 2 | Nano Banana Pro |
|---|---| Dense composition: GPT Image 2 keeps all 6 step labels readable. Nano Banana Pro keeps 5 readable; one label blurs into the central illustration.
4. Edit fidelity Edit: take the previous infographic, change the title to "Plant Energy Cycle", keep all 6 step labels and arrows identical
| GPT Image 2 | Nano Banana Pro |
|---|---| Edit fidelity: GPT Image 2 changes only the title — the other six steps and arrows remain pixel-stable. Nano Banana Pro changes the title cleanly, but quietly redraws one of the step arrows. For multi-round design iteration, that drift adds up.
5. Korean + English bilingual storefront A Korean BBQ restaurant storefront sign at night: top line in Korean "한우 갈비 · 1980년 개업 · 서울 강남구 청담동", bottom line in English "HANWOO GALBI · EST. 1980 · GANGNAM, SEOUL", warm neon lighting
| GPT Image 2 | Nano Banana Pro |
|---|---| Multi-script in one frame: GPT Image 2 nails the Korean, English, and digits — "청담동" and "강남구" hold up character-for-character. Nano Banana Pro builds a more atmospheric street scene (steam, pedestrians, lamplight), but several Korean glyphs on the sign smear, and it adds a second smaller sign that wasn't asked for. Atmosphere ++, text −. For Korean-language brand work, GPT Image 2 is still the safer pick.
6. Magazine cover with stacked typography A magazine cover, masthead "FUSION", date "MAY 2026", main cover line "THE QUIET REVOLUTION IN CHIP DESIGN", three subtitles: "INSIDE TSMC'S 2NM PLAYBOOK / WHY EUROPE IS BUYING NVIDIA / KEN LIU ON AI FICTION", minimalist editorial layout
| GPT Image 2 | Nano Banana Pro |
|---|---| Magazine cover: both got every word right this round — masthead, date, main title, and all three subtitles ("TSMC'S 2NM PLAYBOOK", "WHY EUROPE IS BUYING NVIDIA", "KEN LIU ON AI FICTION") rendered correctly. Nano Banana Pro frames it as a "magazine mockup" with restrained whitespace — arguably the more polished editorial design. On clean English typography, Pro has effectively closed the gap — this is its biggest area of improvement.
7. Math blackboard (special symbols) A classroom blackboard with "iℏ ∂ψ/∂t = Ĥψ" and "E = ∫ ψ* Ĥ ψ dx" in white chalk, with annotations "wave function → ψ" and "Hamiltonian → Ĥ"
| GPT Image 2 | Nano Banana Pro |
|---|---| Special symbols: Greek psi, reduced Planck's constant ℏ, integral sign ∫, the hat on Ĥ — both models render them correctly. The difference is interpretation: GPT Image 2 follows the prompt literally, putting "wave function → ψ" on its own line. Nano Banana Pro rewrites the annotations into a real-blackboard layout — labels on the sides with arrows pointing into the equations. Both are defensible; pick by whether you want literal execution or "looks-like-a-photo" framing.
8. Hand-chalked CJK menu (Chinese / Korean / Japanese) A handwritten chalkboard menu, today's specials in three languages stacked: Chinese "今日特推 · 麻辣牛肉面 ¥38", Korean "오늘의 추천 · 매운 소고기 라면 ₩12,000", Japanese "本日のおすすめ · 辛口牛肉ラーメン ¥1,200"
| GPT Image 2 | Nano Banana Pro |
|---|---| Tri-script handwritten chalkboard: CN / KR / JP across three lines, plus numerals and three currency symbols (¥ / ₩ / ¥) — both models render every CJK character correctly. 麻辣牛肉面 / 매운 소고기 라면 / 辛口牛肉ラーメン all spelled right on both sides. This is the most notable data point for Pro's progress: in a handwritten chalk style with mixed scripts, Nano Banana Pro has caught up. We resampled twice — the result is reproducible, not a fluke. Style-wise, GPT Image 2 leans square / tightly cropped studio sample; Nano Banana Pro leans wider with more visible wood-frame texture. For Asian-market F&B branding, either works — pick by composition preference.
Screenshot Battery (10 Scenarios) We ran 10 common "AI-generated screenshot" scenarios in a single batch — WeChat / Discord / Product Hunt / Twitter / Reddit / LinkedIn / Payment success / Stripe / Feishu (Lark) / Douyin live. Headline: 10 / 10, both models render every prompted character correctly — no text errors on either side. The gap shifted away from "is the text spelled right" and into two more subtle dimensions: UI completeness, and the secondary text the model invents to fill the scene. Pair-by-pair:
9. WeChat chat screenshot A WeChat chat screenshot on iPhone, light mode. Top: "李明 (产品经理)". Bubbles: "明天发布会的 PPT 我刚发到群里了，你看一下文案部分" / "收到，10 点前给反馈" / "辛苦了！晚安🌙"
| GPT Image 2 | Nano Banana Pro |
|---|---| Chinese chat: every prompted string lands character-for-character on both sides — contact name, three messages, timestamps. Nano Banana Pro added the input-bar placeholder "发送给 李明（产品经理）" — a small bonus. Tied.
10. Discord community A Discord desktop screenshot, dark theme. Server "AI Builders", channel "# general". Three messages: sarah_codes "Just shipped v2.3! Check it out 🚀" / mike_dev "Nice! How did the migration go?" / sarah_codes "Smoother than expected — 0 downtime, full rollback ready"
| GPT Image 2 | Nano Banana Pro |
|---|---| Discord: English chat + usernames + timestamps all correct. Nano Banana Pro nails the blue selected-channel highlight (closer to real Discord); GPT Image 2 even fills in the bottom-left user pill "builder_bot". Both presentable.
11. Product Hunt launch page A Product Hunt product page. Product "ImagesV2", tagline "AI image generation that actually renders text". Big orange "▲ UPVOTE 247", badge "🥇 #1 Product of the Day", "324 followers · 18 comments", "@hunter_jane: Finally an AI tool that gets typography right!"
| GPT Image 2 | Nano Banana Pro |
|---|---| Text-equal. GPT Image 2 builds the entire PH page shell — top nav (Products / Community / Launches / Jobs / Sign in / Sign up), "Made by" with 4 maker avatars, comment row with avatar — looks like a real screenshot. Nano Banana Pro renders only the product card itself, more like a design mock.
12. Twitter / X tweet An X tweet by @AnthropicAI: "Claude 4.7 can now hold 100k+ tokens of context with 99% accuracy on needle-in-haystack tests. Available today on the API." Stats: "💬 1.2K · 🔁 8.4K · ❤️ 47K · 👁 892K"
| GPT Image 2 | Nano Banana Pro |
|---|---| Tweet: every engagement number — 1.2K / 8.4K / 47K / 892K — correct on both. GPT Image 2 produces the clean tweet card the prompt asked for; Nano Banana Pro wraps it in a "phone in hand" photo (fingers, phone bezel, blurred background) without being asked. Use GPT2 for screenshot assets, NBP for the "I just posted this" lifestyle shot.
13. Reddit hot post r/MachineLearning post: "I trained a 7B model on a single RTX 4090 and beat GPT-3.5 on reasoning". u/ml_hacker_42 · 6h ago. ▲ 2.4k. 847 comments. Top comment: u/transformer_dad: "This is wild — what dataset did you use?" ↑ 312
| GPT Image 2 | Nano Banana Pro |
|---|---| Reddit: title, username, vote count, comment all correct. GPT Image 2 again builds the full Reddit top nav — hamburger, logo, search, +, bell, profile avatar — completing the real-screenshot illusion. Nano Banana Pro renders only the post card. Same pattern as Product Hunt.
14. LinkedIn endorsement A LinkedIn post by Chen Wei, Senior Engineer at Stripe · 3rd. "Excited to share that I've been promoted to Staff Engineer this week 🎉 Huge thanks to my mentor and the entire payments team for the trust and support over the past 4 years." 142 reactions · 23 comments
| GPT Image 2 | Nano Banana Pro |
|---|---| LinkedIn: two paragraphs of body text + reactions row + Like / Comment / Repost / Send action bar all correct. Nearly a pure tie — UI completeness is comparable too.
15. Payment success screen A mobile payment success screen, large green checkmark, title "支付成功", amount "¥299.00". Details: "订单号: 20260426174233", "商户: imagesv2.ai 年度订阅", "支付时间: 2026-04-26 17:42:33", "支付方式: 余额支付". Button "完成"
| GPT Image 2 | Nano Banana Pro |
|---|---| Payment screen: every Chinese label, the 14-digit order number, the timestamp, the amount — all exact on both. GPT Image 2 outputs a full-screen mock you can drop straight into a deck; Nano Banana Pro frames it inside an iPhone bezel as a product shot. Both are common use cases.
16. Stripe dashboard A Stripe dashboard. Sidebar: Payments / Customers / Subscriptions / Invoices / Reports. Header: "Payments overview · Last 7 days". Big metric: "$48,237.50 Net volume +12.3% vs last week". Chart Apr 20–26. Recent payments table with 3 rows: $29 Pro Monthly / $99 Team Annual / $29 Pro Monthly with emails
[[email protected]],[[email protected]],[[email protected]] | GPT Image 2 | Nano Banana Pro |
|---|---| Stripe: the headline metric, percentage delta, all 3 transaction rows, and all 3 email addresses are correct on both. Nano Banana Pro wraps it in a Safari window (URL bar shows stripe.com, traffic-light buttons present — closer to a real screenshot), but renames the prompt's "Product" column to "Description" — a small deviation. GPT Image 2 follows the prompt strictly.
17. Feishu (Lark) chat A Feishu group chat "产品技术周会 (8)". Three messages: 王浩 "下周二的 review 会议改到周三下午 3 点，地点不变" 10:32 / 张敏 "收到，会议室已经重新预订" 10:33 / 王浩 "@张敏 麻烦把 PRD 链接也同步到云文档" 10:35
| GPT Image 2 | Nano Banana Pro |
|---|---| Feishu: Chinese messages, timestamps, and the blue @张敏 highlight all correct on both. GPT Image 2 wins UI completeness by a wide margin — left rail (消息 / 视频会议 / 日历 / 云文档 / 多维表格 / 通讯录 / 更多), right rail (云文档 / 多维表格 / 日历 / 更多), top search bar with ⌘+K, bottom input area with emoji / @ / scissors / + icons — every one of those ten secondary UI labels is rendered with correct Chinese characters. Nano Banana Pro renders only the chat panel and adds a stray full-width comma after @张敏. For "complete product screenshot" use cases, only GPT2 ships.
18. Douyin (TikTok China) livestream A Douyin livestream, vertical phone format. Top left: "小薇美妆" with red "正在直播" badge and "1.2万人在线". Center: smiling streamer holding lipstick. Three chat overlays: "用户A: 好看！这个色号叫什么？" / "用户B: 主播能展示一下试色吗" / "用户C: 已下单！发货快吗？". Bottom action bar with cart "98"
| GPT Image 2 | Nano Banana Pro |
|---|---| Douyin: streamer name, "正在直播" badge, "1.2万人在线", and all three Chinese chat messages — correct on both. The Easter egg is on the GPT Image 2 side — it added a promo standee behind the streamer that wasn't in the prompt: 「今日福利 / 全场美妆 / 满199减30 / 关注主播 / 领取专属优惠券」. None of those CJK characters were prompted, and every one of them is rendered correctly. This is the strongest implicit signal of GPT Image 2's text reserves: it doesn't just spell what you ask for — it fills in everywhere a real scene "should" have text and gets that right too. Nano Banana Pro wraps the scene in an iPhone frame as a marketing product shot.
Screenshot Battery — Takeaways 10/10 prompted strings correct on both sides — this is Nano Banana Pro's most dramatic catch-up category. But the gap didn't disappear, it shifted to two subtler dimensions:
UI completeness— given the same prompt, GPT Image 2 tends to build the entire product shell (PH top nav, Reddit top nav, Feishu's left + right rails + input area + ⌘+K search), while Nano Banana Pro renders only the prompt's core panel and adds a browser/phone frame to provide context. For "looks like a real screenshot" assets, GPT2 ships in one shot; with NBP, you'll need to composite the chrome yourselfHidden text reserves— GPT Image 2 invents text where a real scene "should" have it (the Douyin promo standee is the smoking gun) and gets that text right too. In complex scenes, this means a lower failure rate
Updated heuristic: single-UI-block screenshots — NBP is now good enough and arguably more "lifestyle-shot"; full product-shell or complex multi-module screenshots — GPT2 still wins.
| GPT Image 2 | Nano Banana Pro | |
|---|---|---|
| Text rendering accuracy | ~99% glyph accuracy | ~94% — major improvement |
| Multilingual (CJK, Hindi, Bengali) | Native, all scripts | Partial — CJK improved, Indic still weak |
| Native reasoning | Yes (Thinking Mode) | Limited — pre-generation planning |
| Edit stability | High — faces, text, layout preserved | Medium-high — small elements drift |
| Speed (typical) | Under 3 seconds | 2–4 seconds |
| Image price | $0.04 – $0.35 | $0.06 – $0.30 |
| Max resolution | 2048 × 2048 (4K upscale) | 2048 × 2048 |
| Best for | Text-heavy, multilingual, editing flows | Photorealism, dense scenes (English-only) |
[When to Choose Which](#when-to-choose-which)
[Choose GPT Image 2 if](#choose-gpt-image-2-if)
- Text accuracy must be flawless — every character has to be right
- You need CJK or other non-Latin scripts
- Editing precision is critical — brand work, design iteration, ad variants
- You're already on the OpenAI / imagesv2.ai stack
- Pure photorealism is the priority and the image has little or no text
- Output is English-only and "good enough" text accuracy is acceptable
- You're already on Google Cloud and want unified billing
- You want a strong B-model to A/B against your primary
Our Verdict This is the first time Google has a model that genuinely competes with OpenAI on image quality. For English-only photorealistic work, Nano Banana Pro is a real alternative — sometimes the skin texture and cinematic lighting are even better. But the text gap is still real: 94% vs 99% means roughly 1 in 20 generations needs a redo. For multilingual or text-heavy work, GPT Image 2 is still the safer default. Our team uses GPT Image 2 as the primary and Nano Banana Pro for purely aesthetic A/B variants.
