  • ESP Large Language Model (LLM) Solution

Espressif enables connected devices to become natural interaction points for LLM-powered experiences — without running the LLM directly on the device. From multimodal input capture to local action execution, and from firmware to cloud and apps, Espressif provides a complete stack for building private LLM agent solutions.
