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

Ringg, a voice and chat agent platform, built an AI customer service system using OpenAI models to automatically handle customer requests like booking appointments and processing insurance. By switching from GPT-4.1 to GPT-5.6 for suitable tasks, Ringg reduced model costs by about 90% while maintaining quality, and now resolves up to 65% of customer calls without human involvement.
