LLM (large language model) is the core engine for agent responses in Retell. Over the past years, many have developed LLM based chatbots, but only a few have explored using LLM for real-time voice conversation.

To ensure our customers have a great end user experience, we have fine-tuned OpenAI model that is suitable for real-time voice conversation.

In this section, we will cover Retell LLM framework, a framework and a set of APIs that allows you to configure a LLM based response system for your voice agents. If you wish to have full control over response system, check out Custom LLM section

For detailed description of each field, check out Retell LLM API Reference
