Model

Choose the LLM that powers your agent. The model directly affects response quality, latency, and cost – a wrong choice can make your agent slow, expensive, or inaccurate.

Recommended: Raven 3.5. PolyAI’s purpose-built conversational model — 24+ languages, sub-300 ms latency, powers both voice and chat.

Available models

PolyAI’s proprietary Raven model family is specialized for customer service across voice and chat. Raven eliminates the trade-off between speed and accuracy – delivering sub-300ms latency, fewer errors, and more natural responses than general-purpose LLMs.

Raven 3.5 is the recommended model for all deployments. It supports voice and chat, 24+ languages, and has powerful auto-reasoning, out-of-domain detection, custom style following, and built-in safety.
