n8n is the fair-code workflow automation platform that pairs a visual builder with code when you need it, and its AI Agent nodes put LLM steps inside any workflow. Opper ships as a dedicated n8n node: install @opperai/n8n-nodes-opper, add your Opper API credential, and the Opper Chat Model node drives your agents with a live dropdown of 700+ models. One key, a choice of EU or US inference, and per-workflow model swaps without rewiring credentials.
n8noninSettings → Community Nodes → Install @opperai/n8n-nodes-opper, then add the Opper API credential and pick the Opper Chat Model in your AI Agent node. Then pick GLM-5.3.
GLM-5.3 runs on the routes below. Route only to EU providers when your data has to stay in Europe.
