Building a Multi-Agent AI System from Scratch (No Frameworks)
Short summary
A tutorial showing how to build a 5-agent pipeline (Researcher → Writer → Editor → Reviewer → Publisher) in pure Python without CrewAI or AutoGen. Each agent calls a local Ollama instance with a role-specific system prompt and passes output to the next. The post includes the full ~50-line implementation, configuration tips like per-agent temperature and model selection, and use case examples.
- •5-agent pipeline in ~50 lines of pure Python using Ollama — no frameworks needed
- •Each agent has a role, system prompt, and passes output sequentially
- •Supports per-agent model selection, temperature tuning, and fallback strategies
Generated with AI, which can make mistakes.
