Google 最新 AI 影像生成器 Nano Banana Pro:功能提升是否值回票價?

Google 推出的 Nano Banana 影像生成模型,憑藉其優秀的影像創作與編輯能力,曾獲得 PCMag 的技術卓越獎。如今,Nano Banana Pro 正式登場,承諾在各方面帶來顯著的性能提升,但它是否真的比原版更強大,值得花錢優先使用?以下是你需要知道的全部資訊。

Nano Banana 與 Nano Banana Pro:有何分別?

Nano Banana 其實是 Google Gemini 系列 AI 影像編輯與生成功能的統稱,並非正式技術名稱。Nano Banana 指的是上一代 Gemini 2.5 模型,而 Nano Banana Pro 則是最新的 Gemini 3 版本。

兩者都能創建及編輯各類影像。原版 Nano Banana 以其圖片融合及保持編輯一致性的能力獲得肯定;而 Nano Banana Pro 則擴展了編輯控制範圍,允許一次合成更多圖片,並能生成更清晰的文字。雖然 Nano Banana Pro 是 Google 目前最先進的 AI 影像技術,但只要善用,原版 Nano Banana 依然表現出色。

如何開始使用 Nano Banana Pro?

用戶可通過 Gemini 聊天機械人應用程式、網站,或 Google 搜尋的 AI 模式來使用 Nano Banana。Nano Banana Pro 僅限付費 Gemini 用戶在 Google 搜尋中使用,但在 Gemini 內部則對免費和付費用戶都開放。付費用戶享有優先使用權,但 Google 限制 Nano Banana Pro 的生成次數,達到上限後會自動切換回原版 Nano Banana。

在 Gemini 的文字輸入欄可切換 Nano Banana 模式,或直接用命令要求 Gemini 創作或編輯圖片。選擇「Fast」即為原版 Nano Banana,「Thinking」或「Pro」則啟動 Nano Banana Pro。用戶只需輸入自然語言描述,並上傳相關圖片,例如上傳一張被手擋住部分的照片,提示「移除手部」,Nano Banana 就會生成移除手部的圖片。

Nano Banana Pro 的神奇之處

Nano Banana Pro 在創作和編輯圖片方面表現卓越。Google 強調其三大核心能力:多圖融合、編輯控制以及文字生成。測試中,作者用一棵樹的照片請兩個模型生成資訊圖表,結果 Nano Banana Pro 在文字呈現上毫無瑕疵,而原版則有幾處錯誤,這在 AI 生成文字中實屬難得。

另外,作者提供四個遊戲角色(Aloy、Andrew Ryan、Nathan Drake 和 Shadowheart)和自己合成一張五人合照,Nano Banana Pro 成功呈現所有角色,而原版則在部分角色外觀處理上出現問題,甚至完全遺漏一位角色。當將圖片轉換為 16:9 長寬比時,Nano Banana Pro 也能輕鬆完成,而原版則經常退回原始比例。

此外,Nano Banana Pro 在輸出解析度上有明顯提升,常見輸出達 2K 水平,較原版約 720p 清晰得多,令生成圖片更銳利、細節豐富,且減少模糊感。Google 甚至宣稱可輸出 4K,但測試中尚未見到。

Nano Banana Pro 的不足之處

儘管進步明顯,Nano Banana Pro 仍有不足。測試其多圖融合能力時,嘗試用客廳照片替換多張亞馬遜產品照片,結果模型反向操作,用客廳替代了亞馬遜物品,無法按指示替換。即使修改圖片標題和提示語言,問題依舊。

在角色合成時,Nano Banana Pro 初始生成了合成版的 Andrew Ryan 和作者,經過細微提示調整,才成功分別呈現多個角色,這顯示模型對提示語言細節的敏感度仍有待提升。

部分 Nano Banana Pro 輸出圖片雖然解析度高,但偶爾會出現模糊,這可能是生成過程中的錯誤,雖不常見,但仍希望能進一步改善。

AI 識別與水印:Nano Banana Pro 影像能否信賴?

隨著 AI 影像生成技術日益強大,利用 AI 傳播誤導訊息的風險也增加。為此,Google 採用 SynthID AI 水印系統,這是一種人眼看不見但電腦可識別的數碼隱形水印。這與 Gemini 影像右下角的 Gemini 標誌不同,後者容易被免費工具移除。

Google 正開發 SynthID 偵測器,讓用戶上傳圖片檢測是否含有 SynthID。測試顯示,即使圖片的可見水印被移除,SynthID 仍能被辨識,雖然未來移除工具可能會進步,但目前這套系統在防偽方面表現不俗。

是否值得嘗試 Nano Banana Pro?

總體來說,Nano Banana Pro 相較原版帶來了實質的提升,尤其在圖片中生成文字的精準度上表現突出。在其他令人失望的 AI 模型更新(如 GPT-5)中,這種進步尤為難得。對於經常使用 AI 影像生成器的人來說,Nano Banana Pro 的吸引力明顯。

不過,對大多數人而言,AI 影像生成是否值得月費訂閱仍有疑問。若你是創意工作者,需要將文字概念視覺化,或在創作過程中嘗試多樣影像,Nano Banana Pro 絕對值得一試。

評論與分析

Google 這次推出的 Nano Banana Pro,顯示了 AI 影像生成技術的快速演進。從提升的文字生成能力到更高解析度輸出,這種進步不僅提升了用戶體驗,也擴大了 AI 在設計、行銷、教育等領域的應用潛力。

然而,從測試中看到的模型對提示語言的高度敏感,提醒我們 AI 雖強,但仍未達到完全自然與靈活的理解能力。這對用戶而言,意味著學習如何精準指令成為關鍵技能,也透露出 AI 在「理解」層面還有很大提升空間。

此外,Google 採用 SynthID 隱形水印技術,是面對 AI 生成內容濫用的積極回應。這不僅有助於保障資訊真實性,也為業界設定了技術標準。未來,隨著 AI 生成圖像越來越普及,如何平衡創新與倫理將是重要課題。

最後,訂閱制模式在 AI 影像生成領域的推行,反映出技術商業化的趨勢。對於一般用戶,是否花費月費取得先進功能,取決於個人需求與使用頻率。隨著技術普及,期待未來能有更多免費或低門檻的選擇,讓創意工具更貼近大眾,推動更多創新與表達。

總括而言,Nano Banana Pro 代表了 AI 影像生成的一大步,值得關注和嘗試,但同時也提醒我們,AI 工具的力量需配合人類智慧與倫理共進,才能真正發揮最大價值。

Prompt (Enhanced, Artistic & Detailed):

A young Asian female inspired by "Imada Mio's" delicate doll-like aesthetic (精緻洋娃娃臉), featuring extraordinarily large, round, and soulful eyes with subtle brown irises, framed by long fluttering lashes. Her face is petite and exquisitely shaped with a defined V-line jaw, soft rosy cheeks flushed with youthful vitality, and plush, natural lips softly parted in a gentle, innocent yet slightly flirtatious expression. Her complexion is luminous and porcelain-smooth.

Her hair is long, dark chocolate brown, and styled in an artfully messy “just woke up” look (剛睡醒的凌亂感), with tousled waves and a touch of natural volume that frames her face and cascades down her shoulders, effortlessly blending wildness and charm.

She wears an oversized, semi-sheer white button-down shirt in a borrowed-from-the-boyfriend style (男友風白襯衫); the shirt slips loosely off her slim shoulders, unbuttoned at the top to reveal graceful collarbones and a hint of décolleté. The hem of the shirt falls mid-thigh, creating a tasteful "bottomless" look (下衣失蹤風格), her bare legs just visible beneath the diaphanous fabric, enhancing a pure yet subtly sexy visual impact.

The image is rendered with a high-key, natural daylight aesthetic reminiscent of Japanese gravure photobooks (寫真集風格): bright, airy lighting softly illuminates her features, casting gentle highlights and diffuse shadows for a dreamy, ethereal effect. Skin is rendered creamy and velvety with impeccable smoothness. The color palette echoes Fujifilm PRO 400H—soft, milky tones with delicate pastels, gentle greens, natural skin, and a nostalgic film grain that adds warmth and authenticity, evoking an elegant, fresh, and intimate atmosphere.

She is posed naturally, perhaps seated on light bed linens or by a sunlit window, exuding a blend of youthful innocence, pure allure, and quiet confidence. Hyper-detailed, cinematic composition, fine-tuned for photorealism yet with a subtle artistic charm. A fierce young boy with short, curly hair stands in an action pose, reaching his hand forward as if unleashing a powerful psychic force. Bright orange energy radiates from his outstretched hand, illuminating her determined expression. he wears a patterned shirt reminiscent of 1980s fashion. Dark, monstrous creatures with elongated limbs and sharp teeth surround his, emerging from swirling smoke and fiery cracks in the environment. The entire scene glows with dramatic orange and red lightning-like streaks, creating an intense, supernatural atmosphere. Highly detailed digital painting, cinematic lighting, dynamic composition, epic fantasy-horror style, dramatic shadows, glowing embers, poster-quality artwork Create a sticker set maintaining 100% of the woman's original facial features from the provided image. Do not alter the face, focusing on ultra-realistic details of the facial structure, eyes, eyebrows, nose, mouth, and expression. The final face must be realistic, not cartoon-like. She has long, voluminous hair.
1. Makeup:Maintain Original Face: We will preserve the structure of your face, eyes, eyebrows, nose, mouth, and expression as closely as possible to the original image to maintain naturalness and uniqueness, while adjusting the tone to be softer:

Eyes: Slightly reduce the sharpness of the Cat Eye eyeliner to a thin line close to the lash line for a softer look, while still maintaining eye definition.
Eyeshadow: Use natural tones like light brown, peach, or beige.
Eyebrows: Original shape, but brushed up to look softer and more natural.
Lips: Glossy, pink-tinted, nude-pink, or coral-toned lipstick/tint to make the lips look full and moisturized. Focus on a bright but not overly intense look.
2. Hairstyle:Natural Voluminous Long Hair: Her hair is long and flowing, but the styling will emphasize natural volume and movement. Soft, natural waves.
3. Outfit:

Attire: A white open-back bodysuit paired with distressed, faded blue denim shorts. There is a message "Kunika" on the shirt.
Shoes: Elegant, simple open-toe flat sandals.
Accessories: Styled freely and fittingly for each scene.
4. Poses & Sticker Elements:Poses: Various poses such as waving, jumping, walking playfully, reading a book, holding up a sign, cheering with both hands, stretching, or making a celebratory gesture, to create a cheerful and friendly atmosphere.Decoration: Include elements like small rainbows, sparkling stars, clear bubbles, hearts, balloons, or light-colored dots to decorate and enhance the fun of each sticker scene.Style: Thin black border around the sticker. Use a modern, rounded 'Itim' style font for the text.Text: Add short emotional phrases written in a cute, beautiful script near the sticker (no speech bubbles/text boxes):

"Hello"
"Love you"
"Submitting work"
"Great"
"Got it"
"Thanks!"
"Wait a sec"
"Ready to care"
"Fight"
"Let's do it"
"So cute"
"OK"
"Sweet dreams:
"Get well soon"
"555"
"You're welcome"
"HBD" 
"OMG" 
"Sorry"
"Got a headache" 
Guidelines: Do not include a text box. Ensure balanced composition with sufficient white space—not cluttered. Match the pose to the text.
Emphasis: Reiterate 'maintain 100% of the original face features from the provided image,' 'ultra-realistic facial detail,' and 'professional studio lighting on face (realistic face, not cartoon face).

Use Cantonese in the stickers.
