更新:2026-10Updated: Oct 2026内容创作

做自媒体最头疼的就是配图——要么没版权,要么太丑。这篇手把手教你用 ChatGPT 写提示词、Midjourney 出图,半小时产出一周的封面。Nothing kills a post like bad or uncredited art. This guide shows how to prompt with ChatGPT and generate with Midjourney — a week of covers in half an hour.

为什么用 AI 做配图Why AI art?

自媒体的图有三难:找图怕侵权、请人贵、自己画不会。AI 出图解决了“快”和“独一份”,但前提是你得会写提示词。Social art faces three pains: copyright risk, designer cost, no drawing skill. AI solves speed and uniqueness — if you can prompt.

工作流总览The workflow

用 ChatGPT 写高质量提示词Write prompts with ChatGPT

别直接把“科技感封面”丢给 Midjourney。先让 ChatGPT 展开成含主体、光线、构图、风格的完整提示词,出图质量立竿见影。Don't feed Midjourney vague phrases. Ask ChatGPT to expand into subject, lighting, composition and style — quality jumps.

示例指令:请把“AI 效率工具封面”扩写成英文 Midjourney 提示词,包含极简风格、蓝紫渐变、留白、8K。Example: expand 'AI productivity cover' into an English Midjourney prompt with minimal style, blue-purple gradient, whitespace, 8K.

版权与商用注意Copyright & commercial

自己生成的图一般可商用,但各平台条款不同;含真人肖像或品牌 logo 需谨慎。发布前确认平台规则,避免下架。Your generations are usually commercial, but platform terms differ; avoid real faces or brand logos. Confirm rules before posting.

小结Wrap-up

ChatGPT 管“说什么”,Midjourney 管“长什么样”,两者配合是自媒体配图最高效的组合。更多工具评测见工具库。ChatGPT says what, Midjourney makes it — the most efficient pairing for social art. See the tool library for reviews.

一套可直接复制的提示词模板Copy-paste prompt templates

下面这套流程固定下来,效率最高。关键是把「主题」交给 ChatGPT 展开成结构化提示词,再交给 Midjourney 出图。Standardize the pipeline: let ChatGPT expand your topic into a structured prompt, then let Midjourney render it.

角色:资深视觉设计师
任务:把「{主题}」扩写成 Midjourney 英文提示词
要求:包含[主体]+[场景]+[光线]+[构图]+[风格]+[色彩]
附加:竖版 4:5,留出上方文字空间,极简,8K

例如把「AI 效率工具」扩写为:floating glass dashboard interface, soft blue-purple gradient lighting, minimalist composition with generous top whitespace, isometric, ultra clean, 8k。Example expansion for "AI productivity tools": floating glass dashboard interface, soft blue-purple gradient lighting, minimalist composition with generous top whitespace, isometric, ultra clean, 8k.

真实案例:一周封面批量产出Real case: a week of covers in one sitting

某技术公众号作者此前每篇配图要花 40–60 分钟找素材,还常遇到版权问题。改用本流程后,他一次生成 5 张封面(每篇 3 张备选),总耗时约 25 分钟,且全部原创可商用。A tech publisher used to spend 40–60 minutes per post sourcing images, often hitting copyright issues. With this pipeline they generate 5 covers (3 options each) in about 25 minutes total, all original and commercially safe.
