Multi-Agent AI Systems: Build Without CrewAI or AutoGen

Transitioning from a single AI agent to a multi-agent system is often necessary when production prompts grow too large, tool selection fails, or latency increases. A practical roadmap helps determine if multiple agents are required. Alternatively, developers can build systems without CrewAI or AutoGen by using local alternatives like ollama. Running models such as llama3.2 on a MacBook ensures privacy, eliminates API costs, and provides fast performance without requiring external servers or expensive tokens.
