A 4-minute read for builders: a free CPU baseline scored 91.0% on 3,080 public bank tickets in my test, plus the cost formula and labelling bill to check.
A 4-minute read for platform leads: the router, eval gate, drift monitor and rollback a fine-tuned small model needs before its benchmark win becomes production.
I had three ways to get structured output from an LLM. I had actual production data to test against. I benchmarked all three on reliability, latency, and prompt overhead. The winne…
I built a gateway that serves several open models via vLLM with routing rules by use case. The H100 benchmarks were better than expected — but the operational complexity of multi-m…
A CNC shop that couldn't afford a $40K Cognex setup got a 97.4% defect-recall vision system built on a Jetson Nano, fine-tuned YOLOv8, and housed in a metal lunchbox.
When school WiFi died for three days, I fine-tuned Phi-3 mini on the curriculum and ran a fully offline reading tutor on a $280 mini-PC under the teacher's desk.
Factory QA is still mostly people staring at screens. A buddy gave me 800 labeled images from a supplier-audit use case and a weekend. Here is what the fine-tune actually caught.
I took a newly released research model, deployed it in the cloud, and benchmarked real-world latency, cost, and reliability against its paper metrics. The gap between paper claims …
Rex rents a 4×A100 box for 72 hours and fine-tunes three open-weight models on the same financial document QA dataset — publishing loss curves, eval deltas, and the inference cost …
I wanted an AI assistant that worked on the train, in the air, and in my basement. No cloud calls. I built one with Ollama, Whisper.cpp, and 200 lines of Rust. Here is the code and…
Rex implements a custom MCP server exposing 14 tools over a Notion-backed internal wiki, wires it to Claude Desktop, and documents the implementation details, latency profile, and …
Rex puts four voice-agent platforms through 1,000 outbound calls each and publishes the full latency, error rate, and cost matrix — including the roll-your-own path that surprised …
