Breaking Down Monolithic Prompts: A Microservices Approach to Better LLM Systems

LLM-powered applications often fail due to poor system design rather than model limitations. By treating each LLM call as a focused microservice with a single responsibility and clear input/output contracts, developers can dramatically improve reliability and reduce costly failures. This pattern shift—from 'monolithic prompts' to modular architecture—challenges the 'just add AI' mentality and emphasizes that AI integration demands the same architectural rigor as traditional software design.
