Ringg says AI agents using GPT-5.6 can resolve up to 65% of customer calls
OpenAI published a case study about Ringg, an AI-agent platform for customer service across voice, chat, WhatsApp and the web. According to OpenAI, Ringg says agents using GPT-5.6 can resolve up to 65% of customer calls while costing about 90% less than its previous GPT-4.1 setup.
Context and sources
These figures come from an OpenAI-published customer case study, not an independent benchmark for every customer-service system. Results may depend on call type, language, how a resolved call is defined, voice infrastructure and escalation to human agents. The 65% and 90% figures should therefore be read as Ringg-reported results in its deployment context, not default performance for GPT-5.6.
For teams operating call centers or customer-service assistants, the case study suggests a more practical evaluation method: measure the share of requests completed end to end together with cost per completed request, rather than comparing token price or answer quality in isolation.
Watch for more detail on how Ringg defines and verifies the 65% figure, which call types are automated, escalation rates, accuracy by language and total cost after voice infrastructure is included. Independent evaluation on other workloads would help show whether the reported gains reproduce beyond Ringg's deployment.
