Near-tie with OpenAI on native conversational audio, with excellent multilingual ability, large context, configurable VAD, multimodal video input, and strong value from Gemini Flash models
Claude Native audio dialog on Gemini 2.5/3 models with strong multilingual coverage, affective/proactive audio features, video+screen input alongside voice, and notably cheaper audio pricing than OpenAI; near-tie with #1 on raw capability, ranked below on ecosystem maturity and production tooling.
Gemini Provides native multimodal inputs (audio and video streaming) at a significantly lower cost than OpenAI, with strong reasoning capabilities and seamless Google Cloud ecosystem integration.
Where Gemini Live API falls short, per the models
- GPT Its strongest live model remains preview-oriented, with session limits and feature differences between model generations that add production risk
- Claude Session/connection limits and rougher developer experience (quotas, preview-labeled features churning) make long-running production deployments more fiddly than OpenAI's.
- Gemini Requires complex WebSocket orchestration and lacks built-in telephony wrappers, imposing high development overhead for production deployment.
