# Blogging with N8N



A comprehensive AI-powered blogging automation system built with N8N that creates, optimizes, and publishes high-quality blog content automatically.



## Project Objective



This project demonstrates a complete automated blogging workflow that transforms a simple topic request into a fully published, SEO-optimized blog post. The system uses multiple specialized AI agents working in sequence to handle every aspect of content creation, from initial research to final publication on your Ghost CMS website.



## ⚠️ Important: Model Selection



**Use high token per minute (TPM) models for optimal performance.** The interactions between multiple AI agents will quickly surpass the 30k TPM limit of most standard models. We recommend starting with **ChatGPT 5-mini** which offers a 200k TPM limit, or other high-TPM models to ensure smooth workflow execution without rate limiting interruptions.



### Model Comparison Table



| Model | Token limits | Request and other limits | Batch queue limits |

|-------|--------------|-------------------------|-------------------|

| gpt-5 | 30,000 TPM | 500 RPM | 900,000 TPD |

| gpt-5-mini | 200,000 TPM | 500 RPM | 2,000,000 TPD |

| gpt-5-nano | 200,000 TPM | 500 RPM | 2,000,000 TPD |

| gpt-4.1 | 30,000 TPM | 500 RPM | 900,000 TPD |

| gpt-4.1-mini | 200,000 TPM | 500 RPM | 2,000,000 TPD |

| gpt-4.1-nano | 200,000 TPM | 500 RPM | 2,000,000 TPD |

| o3 | 30,000 TPM | 500 RPM | 90,000 TPD |

| o4-mini | 200,000 TPM | 500 RPM | 2,000,000 TPD |

| gpt-4o | 30,000 TPM | 500 RPM | 90,000 TPD |



**Key Abbreviations:**

- **TPM**: Tokens Per Minute

- **RPM**: Requests Per Minute  

- **TPD**: Tokens Per Day



### Anthropic Claude Models (Tier 1)



| Model | Maximum requests per minute (RPM) | Maximum input tokens per minute (ITPM) | Maximum output tokens per minute (OTPM) |

|-------|-----------------------------------|----------------------------------------|------------------------------------------|

| Claude Opus 4.x* | 50 | 30,000 | 8,000 |

| Claude Sonnet 4 | 50 | 30,000 | 8,000 |

| Claude Sonnet 3.7 | 50 | 20,000 | 8,000 |

| Claude Sonnet 3.5
2024-10-22 (deprecated) | 50 | 40,000† | 8,000 |

| Claude Sonnet 3.5
2024-06-20 (deprecated) | 50 | 40,000† | 8,000 |

| Claude Haiku 3.5 | 50 | 50,000† | 10,000 |

| Claude Opus 3 (deprecated) | 50 | 20,000† | 4,000 |

| Claude Haiku 3 | 50 | 50,000† | 10,000 |



**Notes:**

- *Claude Opus 4.x models are currently in limited access

- †These models have higher input token limits but are deprecated



## How It Works



The workflow orchestrates a team of AI agents, each specializing in a specific aspect of content creation. Starting with a user's topic request, the system automatically:

1. **Researches** the topic comprehensively

2. **Creates** a structured table of contents

3. **Generates** engaging, well-researched content

4. **Optimizes** for SEO and search visibility

5. **Edits** and polishes the content

6. **Publishes** directly to your Ghost CMS website



## Agent Roles & Responsibilities



### 🤖 Blog Content Orchestrator Agent

**The Project Manager** - Coordinates the entire workflow, manages data flow between agents, and ensures quality control at each stage. This agent handles user interactions, validates data, and manages approval gates before proceeding to publication.



### 🔍 Research Agent

**The Information Specialist** - Conducts comprehensive research using multiple sources including Brave Search, Brave News, and your existing blog content. Creates compelling table of contents, identifies content gaps, and provides research insights for content generation.



### ✍️ Content Generator Agent

**The Master Writer** - Transforms research insights and approved TOC into engaging, well-cited blog content. Researches each section individually, includes proper citations, and maintains consistent style throughout the article.



### 🎯 SEO Optimizer Agent

**The Search Expert** - Performs comprehensive SEO optimization including keyword research, on-page optimization, meta tag generation, and content enhancement recommendations. Ensures maximum search visibility and ranking potential.



### ✂️ Content Editor Agent

**The Quality Assurance Specialist** - Enhances content readability, verifies citations, improves flow, and ensures all links are functional. Creates professional HTML-formatted content ready for publication.



### 🚀 Blog HTML Publisher Agent

**The Publication Specialist** - Generates complete HTML documents with SEO meta tags, schema markup, and social media optimization. Automatically publishes content to your Ghost CMS website using the Ghost Publisher Tool.
