pi-llm turns a stock Raspberry Pi 4 (4GB RAM) into a private local LLM server using 1-bit quantized Bonsai models (1.7B and 4B parameters, under 1GB each). It includes a web chat UI accessible across your home network and implements native tool calling for physical hardware control — LEDs, displays, servo motors, and GPIO peripherals. The setup requires no GPU and no cloud dependency. The Bonsai-8B model family (recently covered here) runs efficiently enough on Pi-class hardware that the tool calling loop — chat message → model decision → GPIO action → result back to model — completes in a few seconds on 1.7B parameters. The project is a clean demonstration of where sub-1GB quantized models are genuinely useful: edge AI applications where latency to a cloud API is unacceptable, privacy matters, and the task is constrained enough that a small model performs adequately. It ships with working examples for five hardware configurations.

RuView is an open-source platform that performs real-time 3D human pose estimation, vital sign monitoring, and presence detection using nothing but cheap WiFi signals from $9 ESP32 microcontrollers. No cameras, no video, no cloud subscription required. The system tracks 17 COCO body keypoints and measures heart rate and breathing by analyzing how bodies disrupt WiFi Channel State Information (CSI) — the same physics used in research labs, now running on a microcontroller you can buy in bulk for single-digit dollars. The architecture fuses WiFi CSI with optional depth and mmWave radar data into a real-time 3D spatial model. On-device spiking neural networks adapt to a new room's RF geometry in under 30 seconds. Total hardware cost for a full room setup: around $140. The software stack is written in Rust with pre-trained models on Hugging Face and an active Python binding layer for downstream ML pipelines. The privacy implications are significant — and cut both ways. RuView can monitor a care home resident's breathing without a camera in their bedroom, or let a smart home detect when all occupants have left. The open-source release makes the technology accessible to indie builders for the first time, but also means the underlying sensing capability is now commodity.
Reviewer scorecard
“The tool calling implementation on hardware GPIO is the genuinely novel part. Most Pi LLM projects just do chat — this one closes the loop so the model can actually actuate things based on conversation. The 1.7B model is fast enough that it doesn't feel like waiting, which changes the interaction model entirely.”
“The Rust implementation is solid and the Python bindings make integration into existing ML pipelines painless. Spiking nets that calibrate in 30 seconds per room is a genuinely impressive engineering achievement. If you're building any kind of ambient intelligence or smart space product, this is the starting point.”
“A 1.7B model doing hardware control is a liability waiting to happen. The model hallucinates — what happens when it hallucinates a servo command? The project has no safety layer, no command confirmation, and no rate limiting on tool calls. Cool demo, genuinely dangerous in any real deployment.”
“WiFi CSI sensing is highly sensitive to room geometry, furniture, and even what people are wearing — repeatability across environments is a known research challenge. The $140 hardware number assumes perfect component sourcing. Real production deployments will need significant RF calibration work before the 17-keypoint claims hold up in arbitrary spaces.”
“This is a preview of the embedded AI future. When every Pi-class device can run a local model with tool calling, the 'smart home' becomes genuinely conversational without routing everything through a cloud API. Pi-llm is early and rough but it's pointing at something real: private, offline, embodied AI agents.”
“Camera-free sensing is the unlocking technology for ambient AI in spaces where visual surveillance is unacceptable — hospitals, elder care, locker rooms, private homes. Commoditizing this with $9 chips and open-source models is a category-defining move. Five years from now WiFi sensing will be standard in smart buildings.”
“The creative applications here are underrated — conversational LED lighting, AI-triggered displays for studio ambiance, physical generative art installations that respond to natural language. The fact that it runs offline matters enormously for gallery or installation contexts where cloud reliability is a risk.”
“The interaction design possibilities are wild — imagine interfaces that respond to your posture, proximity, or even breathing rate without any wearable or visible sensor. RuView could enable ambient, invisible UI paradigms that current computer vision approaches can't touch because of privacy constraints.”
