Circles, a telecom-as-a-service platform, integrates OpenAI’s API and Codex to power AI-native experiences like personalized offers and proactive customer support. The company achieved a 22% lift in average revenue per user and a 9% drop in churn, while also improving development efficiency with Codex. This case study demonstrates how large language models can directly impact key business metrics in the telecom sector, moving beyond experimentation to production-grade use. It also signals growing adoption of OpenAI’s tools in regulated industries, where personalization at scale is a competitive differentiator.
