Ringg cuts customer service costs by 90% with GPT-5.6, resolves 65% of calls via AI

Ringg’s AI agents resolve up to 65% of customer calls with OpenAI

Ringg, an Indian customer service platform, uses OpenAI's GPT-5.6 family to power voice and chat agents. It handles over 7 million calls monthly, with AI resolving up to 65% of requests and a 4.8 CSAT score. The trick: route real-time conversations to GPT-4.1, post-call analysis to GPT-5.6 Terra, and evals to GPT-5.6 Sol. Moving to GPT-5.6 cut costs by 90% for some workloads. The post doesn't clarify whether the 65% resolution rate is fully automated or includes human handoffs, nor does it disclose specific latency numbers.
