AI 绘画工具全攻略：Midjourney / Stable Diffusion / Flux 怎么选 The Complete AI Art Guide: Midjourney vs SD vs Flux
为什么 AI 绘画值得认真对待 Why AI Art Deserves Serious Attention
2024 年，AI 绘画已经不是什么新鲜事了。但正是这种不新鲜，让很多人忽略了一个事实：AI 绘画工具已经从玩具进化成了真正的生产力工具。无论是做自媒体配图、电商产品图、游戏素材、建筑设计概念图，还是纯粹的艺术创作，AI 绘画都能大幅提升你的效率。问题不再是 AI 能不能画画，而是我应该用哪个工具画。 In 2024, AI art is no longer news. But precisely this familiarity has led many people to overlook a fact: AI art tools have evolved from toys into genuine productivity tools. Whether you are creating social media graphics, e-commerce product images, game assets, architectural concept art, or pure artistic creation, AI art can dramatically boost your efficiency. The question is no longer can AI draw? but which tool should I use?
目前市面上最主流的 AI 绘画工具有三款：Midjourney、Stable Diffusion（SD）和 Flux。它们各有特色，适合不同的人群和场景。这篇文章会从画质、上手难度、价格、可控性、适用场景等多个维度进行全面对比，最后根据你的实际需求给出推荐。 The three most mainstream AI art tools on the market right now are Midjourney, Stable Diffusion (SD), and Flux. Each has its own characteristics and suits different people and scenarios. This article will comprehensively compare them across dimensions like image quality, learning curve, pricing, controllability, and applicable scenarios, then give recommendations based on your actual needs.
三款工具全面对比 A Comprehensive Comparison of Three Tools
极高。V6 版本的画质几乎无可挑剔，色彩、构图、光影都接近专业摄影级别。尤其擅长写实风格、概念艺术和插画风格。Extremely high. V6 quality is nearly flawless in color, composition, and lighting, approaching professional photography level. Especially excels at realistic, concept art, and illustration styles.
取决于模型和参数。使用 SDXL 或精品 Checkpoint 可以达到极高画质，但需要大量调试。Depends on the model and parameters. Using SDXL or quality checkpoints can achieve extremely high image quality, but requires extensive tuning.
非常高。Flux.1 Pro 的文字渲染和指令遵循度甚至超过 MJ，特别适合需要精准控制画面内容的场景。Very high. Flux.1 Pro text rendering and prompt fidelity even surpass MJ, especially suitable for scenarios requiring precise control.
低。在 Discord 里输入命令即可生成，几分钟就能上手。Low. Generate by typing commands in Discord, you can start in minutes.
高。需要自己部署环境，理解采样器、CFG Scale、步数等大量参数。学习曲线陡峭。High. Need to set up your own environment and understand many parameters. Steep learning curve.
中低。通过网页直接使用，Flux Schnell 免费开放，API 调用也比较简单。Medium-low. Use directly through the web, Flux Schnell is free, API calls are simple.
10 美元/月起，30 美元/月无限制。需要国际支付方式。From $10/month, $30/month unlimited. Requires international payment.
开源免费。本地跑需要好显卡（推荐 RTX 4060 以上），租云算力另算。Open source and free. Running locally needs a good GPU (RTX 4060+ recommended).
Schnell 免费可本地部署，Pro 版通过 API 按量计费。成本介于 MJ 和 SD 之间。Schnell is free and deployable locally, Pro billed via API. Cost between MJ and SD.
中等。V6 指令遵循度高，但精细控制仍有限，主要靠 Prompt 和参数调整。Medium. V6 prompt fidelity is high but fine control is still limited, relies on prompts and parameters.
极高。ControlNet 精确控制姿势和线稿，LoRA 固定风格或人物，Inpainting 局部修改。三款中最强。Extremely high. ControlNet for precise pose and sketch control, LoRA for styles/characters, Inpainting for local edits. Most controllable of the three.
高。Pro 文字渲染特别突出，可在画面中生成精确文字，对复杂场景理解也很强。High. Pro text rendering is outstanding, generates precise text in images, strong complex scene understanding.
不同需求，不同选择 Different Needs, Different Choices
选择哪个工具，本质上取决于三个问题：你要画什么、你的技术水平如何、你愿意花多少钱。 Which tool to choose essentially depends on three questions: what to draw, your technical level, and budget.
如果你是纯新手，只是想快速出好看的图：选 Midjourney。上手最快，出图质量最高，10 美元/月完全可接受。不需要懂技术概念，会描述想要的东西就行。 If you are a complete beginner wanting nice images fast: Choose Midjourney. Fastest start, highest quality, $10/month is reasonable. No technical concepts needed.
如果你是设计师或插画师，需要精细控制：选 Stable Diffusion。学习成本高，但 ControlNet 加 LoRA 让你实现几乎任何创作需求。 If you are a designer needing fine control: Choose Stable Diffusion. Higher learning cost, but ControlNet + LoRA enables almost any creative need.
如果你需要画面中包含精确文字：选 Flux。做海报、Logo、社交媒体封面等需要文字的场景，Flux 远超其他两个。 If you need precise text in images: Choose Flux. For posters, logos, and social covers, Flux far outperforms the others.
不要一上来就纠结选哪个工具。如果完全没接触过 AI 绘画，先用 Midjourney 玩一周，感受 AI 绘画能做什么、不能做什么。有了基本认知后，再根据需求决定是否深入学习 SD。另外，不要只关注工具本身——学会写好 Prompt 才是核心技能。同样一个 Midjourney，有人只能生成普通的图，有人能生成惊艳的作品，差距就在 Prompt 上。多看优秀作品的 Prompt 怎么写的，多练习，这是提升最快的路径。Do not agonize over which tool from the start. If new to AI art, play with Midjourney for a week first. Once you have a basic understanding, decide based on your needs whether to dive into SD. Also, do not just focus on the tool itself — learning to write good prompts is the core skill. With the same Midjourney, some generate ordinary images while others create stunning works. The difference is in the prompts. Study excellent prompts and practice more.
一个容易被忽视的点：版权与商用Copyright and Commercial Use
三款工具版权政策不同，商用需注意。Midjourney 付费用户可商用；SD 开源模型输出一般可商用（看 License）；Flux 开源版可商用，Pro 版看具体条款。不管用哪个，商用前仔细阅读版权政策，避免纠纷。Copyright policies differ. Midjourney paid users can commercialize; SD open-source outputs generally commercial (check license); Flux open-source versions commercial, Pro depends on terms. Read copyright policies before commercial use.
