Cartridges is an open-source single-GPU PyTorch reproduction of two recent papers on KV-cache compaction for long-context LLM inference: "Cartridges" (lightweight long-context representations via self-study condensation) and "STILL." Both methods address the same bottleneck — KV caches grow linearly with context length and quickly become the dominant memory consumer in long-context inference, making extended context windows impractical on consumer hardware. The Cartridges paper proposes condensing long contexts into compact "cartridge" representations through a self-study phase, trading some context fidelity for dramatic memory reduction. STILL uses a different approach focused on selective layer-wise compression. This repository makes both reproducible on a single consumer GPU — previously these required multi-GPU setups accessible mainly to research labs. KV-cache memory is one of the primary bottlenecks preventing long-context models from running efficiently on local hardware. A working single-GPU reproduction of these techniques is directly useful to anyone building long-context applications outside of cloud environments, and may accelerate community development of hybrid compaction strategies not in the original papers.

RuView is a WiFi DensePose system that converts commodity WiFi signals into real-time human pose estimation (17 COCO keypoints), vital sign monitoring (breathing and heart rate), and presence detection — all without cameras, wearables, or any line-of-sight requirement. It runs on $9 ESP32-S3 edge hardware, making privacy-preserving human sensing accessible at near-zero hardware cost. The system uses spiking neural networks (SNNs) that adapt to new rooms in under 30 seconds via online STDP learning — no new training data required when you change environments. It achieves 92.9% PCK@20 accuracy with just 5 minutes of synchronized training data and exploits neighbors' WiFi routers as free radar illuminators via multipath modeling. The full stack runs on a $9 microcontroller with a companion Python processing server for the heavier inference. Applications span eldercare monitoring without privacy-invasive cameras, smart home occupancy detection, clinical vital sign monitoring, and security systems that work through walls. The privacy angle is genuinely compelling — you get full presence and activity awareness without any video data being captured or stored. Released April 22, 2026.
Reviewer scorecard
“KV-cache memory is the wall that stops long-context models from running locally. A clean single-GPU reproduction of two compaction approaches in one repo is exactly what the community needs to evaluate tradeoffs without re-implementing from scratch. The self-study condensation approach in Cartridges could be a game-changer for local inference.”
“The $9 hardware cost is the headline — prior WiFi sensing research required expensive SDR hardware or proprietary routers. ESP32-S3 + online STDP learning that adapts to new rooms in 30 seconds is a practically deployable combination. For smart home, eldercare, or building automation use cases this opens a category that was previously research-only.”
“Two stars on GitHub and posted within hours — this is as early as it gets. Reproducing research papers is notoriously error-prone and the author hasn't had time to validate results against original paper benchmarks. Worth watching, but don't build production systems on it until the community has stress-tested the implementation.”
“WiFi sensing accuracy degrades significantly in multi-person environments and with thick concrete walls — the 92.9% PCK@20 figure is likely single-occupant in a controlled lab setting. Interference from neighboring WiFi networks, Bluetooth, and microwave ovens creates real-world noise floors not represented in benchmarks. Treat this as a research demo until independent real-world replication confirms the accuracy claims.”
“The open-source community making frontier inference techniques accessible is what drives capability proliferation. Every time a technique goes from 'paper + multi-GPU cluster' to 'laptop + single GPU,' the addressable user base for long-context applications expands by orders of magnitude. Cartridges points directly at that transition.”
“Camera-free sensing resolves the fundamental tension between ambient intelligence and privacy. If WiFi-based pose and vital signs reach camera-comparable accuracy, the entire smart building and healthcare monitoring market re-orients around passive RF sensing rather than video. At $9 per node, this could be the hardware substrate for genuinely ubiquitous ambient AI.”
“Honestly too deep in the research weeds for most content creators unless you're specifically building local long-context pipelines. This is a tool for ML engineers and researchers first. If the techniques prove out, the benefits will eventually arrive via model updates rather than DIY implementation.”
“The privacy-by-design framing is what makes this compelling beyond the technical novelty. Interactive installations, immersive environments, and wellness spaces that respond to occupant presence and movement without surveillance cameras are suddenly buildable by small teams. The creative applications for responsive environments are wide open.”
