# Automate Content Generator for WordPress with DeepSeek R1
### 1. Workflow Overview
This workflow automates the generation and publishing of SEO-friendly blog content on a WordPress site using DeepSeek AI models and OpenAI’s image generation capabilities. It integrates Google Sheets as a content idea source and tracking tool, WordPress for content publishing, and AI services for content and image creation.
The workflow is logically divided into the following blocks:
- **1.1 Input Reception and Data Fetching**
Starts manually and fetches content ideas from Google Sheets.
- **1.2 Prompt Preparation**
Extracts and sets the prompt for AI content generation.
- **1.3 AI Content Generation**
Generates the article and title using DeepSeek AI models.
- **1.4 WordPress Post Creation**
Creates a draft post on WordPress with the generated content.
- **1.5 AI Image Generation and Upload**
Generates a photorealistic cover image with OpenAI DALL-E, uploads it to WordPress, and sets it as the featured image.
- **1.6 Google Sheets Update**
Updates the original Google Sheets document with post metadata for tracking.
