This integration method is maintained but no longer actively developed. For the best experience and latest features, use our new [AI Gateway](/gateway/overview) with unified API access to 100+ models.
OpenAI's Realtime API enables low-latency, multi-modal conversational experiences with support for text and audio as both input and output.
By integrating with Helicone, you can monitor performance, analyze interactions, and gain valuable insights into your real-time conversations.
