Dev builds sourced comparison of realtime speech-to-speech models across six providers
mahimairaja · reddit · 2026-09-17
A developer turned his realtime voice model research into a public reference comparing OpenAI Realtime, GPT-Live, Gemini Live, Amazon Nova Sonic, Grok Voice, and Ultravox. It covers interruption behavior, protected speech, text responses, tool execution, conversation history, integrations, pricing estimates, evals, and open-weight options. Every row links to sources with last-verified dates; unknowns are marked ? rather than guessed.
