Retell AI Performance Tuning

Overview

Implementation patterns for Retell AI performance tuning — voice agent and telephony platform.

Prerequisites

• Completed retellai-install-auth setup

Instructions

Step 1: SDK Pattern

import Retell from 'retell-sdk';
const retell = new Retell({ apiKey: process.env.RETELL_API_KEY! });

const agents = await retell.agent.list();
console.log(`Agents: ${agents.length}`);

Output

• Retell AI integration for performance tuning

Error Handling

Examples

Improve response latency with a measured canary

Capture baseline end-to-end latency, model latency, transfer outcome, and completion rate for a synthetic test suite before changing an agent setting. Apply one prompt, model, or integration change to a preview version and repeat the same suite. Promote to a small canary only if latency improves without a drop in completion or an increase in handoffs; otherwise restore the prior version and retain the comparison as the performance decision record.
