OpenAI, GPT-5급 추론 능력을 가진 GPT-Realtime-2 시리즈 공개

OpenAI's GPT-Realtime-2 series represents a fundamental transformation of voice interfaces from simple command-response systems to reasoning-driven platforms capable of simultaneous inference, tool execution, translation, and transcription in real-time. Supporting 70+ input languages translated to 13 output languages with GPT-5-level reasoning, these models address critical gaps that have prevented voice from becoming a true software interface. Production deployments already demonstrate substantial impact, with Zillow achieving a 26-point increase in call success rates, signaling that voice AI has matured into a viable platform for complex, multi-step interactions.
