Customer Service Automation
Zendesk needed to move beyond intent-classification bots that failed on nuance, follow-up questions, and edge cases, while reducing setup time and letting customers automate more service work without rebuilding their support stacks.
Reported impact
Zendesk cut setup time from days to minutes, built agents that can move toward 80% automation with stronger quality controls, and created an internal model-evaluation program that lets teams test and deploy new models in under 24 hours.
Zendesk rebuilt its service automation stack around OpenAI models and a multi-agent architecture designed for resolution instead of mere containment. The platform starts with a task-identification agent that converses with the end user to disambiguate intent, then a conversational RAG agent grounds answers in the ongoing dialogue and retrieves policy or FAQ material with the right context. A procedure-compilation agent converts business rules written in natural language into structured flows, and a procedure-execution agent calls APIs, triggers workflows, and updates systems inside Zendesk guardrails. Zendesk also added an agent builder with natural-language procedure authoring, reasoning controls for auditability, and a benchmarking pipeline that tests models like GPT-4o and o3-mini on latency, cost, and quality so teams can evaluate and ship changes in under 24 hours.
A user request enters the task-identification agent, which clarifies intent and passes context to the conversational RAG agent for grounded retrieval. Procedure compilation translates business rules into structured actions, procedure execution performs API and workflow steps, and reasoning controls plus evals record how the model behaved before and after deployment.
