Tolan developed a voice-first AI companion using GPT-5.1 that delivers responses with minimal delay while reconstructing context in real-time and maintaining consistent personality traits across conversations. The system prioritizes low-latency interactions, enabling natural back-and-forth dialogue without noticeable pauses. This approach allows users to engage with an AI that remembers previous exchanges and adapts its communication style accordingly.
