n8n Multi-Agent Engineering Department: CTO Agent Orchestrates O3 and Six Specialist Agents

Import n8n template → configure OpenAI credentials → send technical requests via Chat Trigger → CTO (o3) analyzes and delegates to Architecture/DevOps/Security/QA/Backend/Frontend Agents (gpt-4.1-mini) → receive comprehensive technical deliverables

Read the case’s method and prerequisites

Prerequisites: accessible n8n instance with LangChain nodes enabled; OpenAI API key supporting o3 and gpt-4.1-mini; webhook capability for chat messages. Boundaries: this is an official n8n workflow template—import the workflow JSON and configure credentials per node. Specialist Agents use the n8n dynamic expression `={{ $fromAI(...) }}` in their prompt fields; the framework injects the user message at runtime, so these are not traditional static system prompts. Cost: o3 is used only for the CTO Agent's strategic decisions; specialists use gpt-4.1-mini to reduce cost (source claims ~90% reduction). Not tested by this site.

Read the case’s method and prerequisites

Prerequisites: n8n instance; OpenAI API credentials (openAiApi); Git repository access (GitHub/GitLab/Bitbucket API or SSH); notification channel (Slack/email/webhook). Costs depend on GPT-4o token usage and n8n hosting.

n8n Multi-Agent Cold Email Campaign Generator: O3 Director + GPT-4.1 Specialists

Build a chat-triggered multi-agent workflow in n8n: an O3 Director Agent orchestrates strategy while six GPT-4.1-mini Specialist Agents run research, copywriting, personalization, sequencing, deliverability, and analytics in parallel, then integrate into a complete cold email campaign plan.

Read the case’s method and prerequisites

Prerequisites: accessible n8n instance (self-hosted or cloud); OpenAI API Key configured in n8n credentials. Input: send a natural-language request via the n8n Chat Trigger (e.g., "Create a cold email campaign for SaaS CTOs"). Output: an integrated campaign plan returned by the Director Agent. Cost: depends on OpenAI API usage; author claims ~90% savings by using O3 only for strategy and GPT-4.1-mini for tasks (unverified).
