The Raspberry Pi AI HAT+ 2 is an add-on board based on the Hailo-10H AI accelerator that brings
generative AI capability to Raspberry Pi 5.
With 8GB of dedicated on-board RAM, the AI HAT+ 2 is ideal for running large language models (LLMs)
and vision-language models (VLMs) locally, leaving the host Raspberry Pi 5 free to handle other tasks.
The AI HAT+ 2 delivers reliable, low-latency, accelerated generative AI at the edge, making it the
perfect choice for applications including offline process control, secure data analysis, facilities
management, and robotics.
Performance
The AI HAT+ 2 delivers 40 tera-operations per second (TOPS) of INT4 inferencing performance, with
computer vision performance equivalent to the 26 TOPS AI HAT+.
A set of sample models is provided by Hailo. Users can also train custom models to suit their
application, such as speech to text, translation, or visual scene analysis.
Integration
Like the original Raspberry Pi AI HAT+, the AI HAT+ 2 communicates using Raspberry Pi 5's PCI Express interface.
When the host Raspberry Pi 5 is running an up-to-date Raspberry Pi OS image, it automatically detects
the on-board Hailo accelerator and makes it available for AI computing tasks.
The built-in rpicam-apps camera applications in Raspberry Pi OS natively support the AI module,
automatically using the accelerator to run compatible post-processing tasks.
