🇹🇼 AI 圖片生成實戰：Midjourney、DALL-E、Flux 誰最強？
AI 圖片生成在 2026 年已經進入成熟期。三大主流工具——Midjourney V7、DALL-E 4、Flux Pro——各有擅場。我用同樣的提示詞測試了三個工具，以下是實測結果。
Midjourney V7：藝術感之王
Midjourney 一直是視覺品質的標竿。V7 版本的進步：
- 風格一致性：同一角色在不同場景中能維持一致的外觀
- 光影處理：業界最自然的光影效果，特別是人像攝影風格
- 文字渲染：終於能正確生成圖片中的文字了（雖然偶爾還是會出錯）
- 缺點：仍然需要透過 Discord 或網頁版操作，API 存取有限制；月費不便宜（Pro 方案 /月）
DALL-E 4（OpenAI）：最聽話的助手
DALL-E 4 整合在 ChatGPT 裡，優勢在於指令遵從性。
- 提示詞理解：三者中最能精確理解複雜描述的工具
- 編輯能力：局部修改（inpainting）做得最好，可以精確指定要修改的區域
- 整合優勢：在 ChatGPT 對話中直接生成，工作流最順暢
- 缺點：藝術風格的多樣性不如 Midjourney；有時畫面略顯「AI 感」
Flux Pro（Black Forest Labs）：開源陣營的翻身之作
Flux 是 2024-2025 年最大的驚喜。作為開源模型，它的表現令人刮目相看。
- 速度：生成速度最快，特別是在本地部署時
- 開源自由度：可以自由微調、商用，沒有使用限制
- 真實感：照片級真實感已經追上商業模型
- 缺點：需要較強的 GPU（至少 12GB VRAM）才能本地運行；社群資源不如 Midjourney 豐富
實測比較：三個場景
我用三個典型場景做了比較：
- 產品照片：DALL-E 4 勝出——最能精確呈現產品特徵
- 藝術插畫：Midjourney V7 勝出——美學品質無可挑剔
- 人像攝影：三者不相上下，但 Midjourney 的膚色和光影最自然
結論：沒有完美的工具
如果你是設計師或創作者，追求最高視覺品質，Midjourney 仍然是首選。如果你需要 AI 圖片生成整合在工作流中，DALL-E 4 最方便。如果你重視隱私、成本或需要微調，Flux 是最好的選擇。好不好用，試了才知道。
🇺🇸 AI Image Generation Showdown: Midjourney vs DALL-E vs Flux
AI image generation has reached maturity in 2026. The three major tools — Midjourney V7, DALL-E 4, and Flux Pro — each excel in different areas. I tested all three with identical prompts. Here are my findings.
Midjourney V7: The Aesthetics King
Midjourney has always set the benchmark for visual quality. V7 improvements include:
- Style consistency: Same character maintains consistent appearance across different scenes
- Lighting: Industry-leading natural lighting effects, especially for portrait photography
- Text rendering: Can finally generate text in images correctly (though occasional errors persist)
- Downsides: Still requires Discord or web interface; limited API access; pricey Pro plan at /month
DALL-E 4 (OpenAI): The Most Obedient Assistant
DALL-E 4 is integrated into ChatGPT, with its main advantage being instruction following.
- Prompt understanding: Best of the three at precisely interpreting complex descriptions
- Editing capabilities: Best inpainting — can precisely specify regions to modify
- Integration advantage: Generate directly within ChatGPT conversations for the smoothest workflow
- Downsides: Less artistic style variety than Midjourney; images sometimes have an obvious "AI look"
Flux Pro (Black Forest Labs): The Open-Source Contender
Flux has been the biggest surprise of 2024-2025. As an open-source model, its performance is remarkable.
- Speed: Fastest generation times, especially when deployed locally
- Open-source freedom: Free to fine-tune, use commercially, with no restrictions
- Photorealism: Photo-realistic quality has caught up with commercial models
- Downsides: Requires a decent GPU (at least 12GB VRAM) for local use; community resources not as rich as Midjourney
Head-to-Head: Three Scenarios
I compared all three across three typical use cases:
- Product photos: DALL-E 4 wins — most accurate at rendering product features
- Artistic illustrations: Midjourney V7 wins — impeccable aesthetic quality
- Portrait photography: Essentially a tie, but Midjourney edges ahead with the most natural skin tones and lighting
Conclusion: No Perfect Tool
If you are a designer or creator pursuing the highest visual quality, Midjourney remains the top choice. If you need AI image generation integrated into your workflow, DALL-E 4 is most convenient. If you prioritize privacy, cost, or need fine-tuning, Flux is the best pick. You won't know until you try.
