Comment “engineer” to get the link. Most people stop at RAG because it feels advanced. But retrieval alone doesn’t create autonomy. Real AI engineering starts when systems can make decisions, use tools, recover from failures, and coordinate workflows. Level 4 systems usually combine agents, memory layers, eval pipelines, guardrails, and human approvals into one architecture. That’s why companies building production AI care less about prompts now and more about orchestration reliability. If you’re learning AI today, study systems design alongside prompting. That’s the actual leverage. #aiengineer #aieducation #aicourse #ai #chatgpt
