Run n8n on GPT-5.1-Codex Mini
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.
