Vercel 發表全新的 OG Image Generation 功能，解決傳統使用 Puppeteer 截圖導致速度慢、成本高的痛點。該技術基於 Edge Functions 與 Satori 引擎，允許開發者直接使用 React、HTML 和 CSS 來設計動態 Open Graph 圖片。這使得社交分享卡片的生成速度提升至毫秒級，且能完美與 Next.js 等框架整合。
Vercel has officially launched "OG Image Generation" (Open Graph image generation), a brand-new technology designed to solve the pain points of dynamically generating social sharing card images for web pages. In the past, to give each web page (such as an e-commerce product page or a blog post) its own unique, dynamically generated social sharing image, developers typically had to use headless browsers like Puppeteer inside Serverless functions to take screenshots of web pages. However, this approach suffered from long cold start times, high memory consumption, and image generation that often took several seconds — seriously impacting performance and cost.
