In an orchestra each musician plays their own instrument and the conductor makes sure everyone comes in at the right moment. Real work in AI systems rarely ends with a single model call. Understanding a customer email, finding the customer in the CRM, checking the order status, writing the reply and handing over to a person if needed are separate steps. Orchestration is the layer that puts those steps in order, passes data between them and decides what happens when a step fails. ## What does it coordinate? - Models: a fast, cheap [small model](https://www.qanatone.com/en/nedir/slm-nedir/) for simple classification and a large model for complex reasoning. - Tools: APIs, databases and search called through [function calling](https://www.qanatone.com/en/nedir/function-calling-nedir/). - Knowledge: documents retrieved with [RAG](https://www.qanatone.com/en/nedir/rag-nedir/) and [memory](https://www.qanatone.com/en/nedir/ai-memory-nedir/). - Agents: several [agents](https://www.qanatone.com/en/nedir/ai-agent-nedir/), each specialised; one researches, one writes, one checks. - Rules: [guardrail](https://www.qanatone.com/en/nedir/guardrail-nedir/) checks, steps that need human approval, error handling and retries. ## Which tools are used? LangChain, LangGraph and LlamaIndex are widely used open source frameworks for language model applications. Tools such as n8n and Make connect AI steps to existing business systems through visual workflow editors. Major model providers also offer their own agent development kits. Simple flows may need only a few lines of code; designing the flow itself comes before choosing a tool. ## Why does it matter? In businesses, reliable results usually come from a well built workflow rather than a single powerful model. In a workflow every step can be measured, debugged and replaced when needed. Costs fall too, because each step can use the cheapest component that does the job. This is one of QANATONE's working principles: connecting the right channels and tools instead of building everything from scratch. Our [automation](https://www.qanatone.com/en/hizmetler/otomasyon/) projects are built this way. ## More articles [Model Type · SAM ### What is the Segment Anything Model (SAM)? 15 Sep 2026 · 2 min](https://www.qanatone.com/en/nedir/sam-nedir/)[Model Type · SLM ### What is a small language model (SLM)? 15 Sep 2026 · 2 min](https://www.qanatone.com/en/nedir/slm-nedir/)[Marketing · Social Media ### What is social media marketing?
