Cut an Enterprise RAG Pipeline’s Latency and Cost by Calling the LLM Less, Not by Buying a Faster Model
Enterprise Document Intelligence [Vol.1 #9ter] - The pipeline from Article 9 calls a model at several steps to be sure it is right. On easy questions that is needless latency. A per-question signal routes them past the model, about two seconds saved for a keyword match. The post Cut an Enterprise RAG Pipeline’s Latency and…

How to Utilize OKF Efficiently to Enable Knowledge Exchange Among LLMs
Google's Open Knowledge Format (OKF) is a Markdown+YAML skeleton for sharing knowledge between humans and AI agents. This post reuses that skeleton for a very specific job — an agent-to-agent hand-off of pre-tokenized integer arrays between three Qwen2.5-Coder models (7B, 3B, 1.5B) — and shows the 28–37% TTFT reduction plus the one full-vocabulary equivalence check…
Tutorial: Motion-Reactive LED Devil Horns with Gesture Animations
Check out the latest tutorial from Erin St Blaine: make a pair of glowing LED devil horns that react to your movements. These lightweight paper-mâché horns are packed with NeoPixels and powered by an Adafruit RP2040 Prop-Maker Feather. The onboard accelerometer senses head movement and triggers different animations — tilt your head for a slow…
