A automated customer support

High-volume e-commerce support often faces severe bottlenecks, causing lost sales and poor customer satisfaction. The AMD Smart Customer Support & KB Routing Agent resolves this by automating initial email handling, intent routing, and product troubleshooting using high-performance AI inference on AMD Instinct GPUs. How It Works Orchestrated in n8n, the workflow listens for unread customer support emails via Gmail OAuth 2.0. Incoming messages are dispatched to GLM-5.3-Flash hosted on the AMD Developer Cloud, which extracts structured JSON metadata—identifying intent, sentiment, product SKUs, and clean query summaries. Key Capabilities Intent & Sentiment Categorization: Instantly sorts inquiries into distinct channels (Product Issues, Returns/Refunds, or General Support). Automated Knowledge Base (KB) Checks: Queries internal product documentation to answer technical questions automatically. Smart Self-Evaluation & Escalation: If the model cannot guarantee an accurate answer (UNKNOWN_ANSWER), it avoids hallucinating and gracefully routes the ticket to human agents while informing the customer. Multi-Branch Action Routing: Triggers specific workflows depending on the category, ensuring smooth operational handoffs. Technical Stack AI Model: GLM-5.3-Flash (AMD Developer Cloud API) Orchestration: n8n Workflow Automation Triggers & APIs: Gmail OAuth 2.0 & OpenAI-compatible Chat Completions Endpoint Business Impact By offloading repetitive product inquiries and enforcing strict human guardrails for complex cases, merchants reduce average first-response times from hours to seconds while cutting operational support costs significantly.
