AI Content Generation at Scale: GPT-4, DALL-E 3, and Next.js

How to build a multi-tenant content generation dashboard that creates blog posts with GPT-4 and matching visuals with DALL-E 3 from a single prompt.

AI Content Generation at Scale: GPT-4, DALL-E 3, and Next.js

Marketing teams need content fast. We built a dashboard that generates a complete blog post with header image from a single topic prompt.

1. Content Pipeline

typescript
[Topic Input] ──> [GPT-4: Generate Outline] ──> [GPT-4: Write Sections]
                                                         │
                                                   [DALL-E 3: Header Image]
                                                         │
                                                   [Rich Text Editor Preview]

2. Multi-Tenant Architecture

Each agency gets isolated data using Prisma's row-level security. Content is stored per-tenant with separate API keys and brand style guides.

3. Export Integrations

Generated content exports directly to WordPress, Webflow, and Shopify via their respective APIs, eliminating copy-paste workflows.

Summary

By chaining GPT-4 for text and DALL-E 3 for visuals, agencies produce publication-ready content in minutes instead of days.
