Hi, I'm David W. Rose
I tinker with machines. Some of them think. My projects range from coding agents and LLM benchmarks to maps, computer vision, personal infrastructure, and vehicle electronics. I publish the useful results and strange side quests as cipher982.

Nearby Prompts, Distant Trajectories
July 24, 2026
Chaos isn't randomness. It's deterministic amplification of small differences. I spent a few weeks asking how far that lens gets us with modern LLMs at inference time. Part 1 of three: the framing.

A 5 GB Docker Image for a 7.4 MB Model
June 13, 2026
A deploy hung for fifteen minutes. The cause was 3.9 GB of NVIDIA CUDA wheels being installed for a model that runs on CPU. This is the side quest from the HDR project: why PyTorch ships a CUDA runtime you don't ask for, what inference actually needs, and what I learned porting GMNet to tinygrad by hand and proving the outputs identical to a fraction of a pixel.

Restoring HDR to AI-Edited iPhone Photos: The Long Version
May 2, 2026
An iPhone HDR JPEG is two images hiding inside one file, stitched together by a spec war between Google and Apple. AI editors throw the second one away. This is the story of reconstructing it: gain maps, APP2 segments hand-assembled from iPhone hex dumps, a CNN from ICLR 2025, a 5 GB Docker build caused by a 7.4 MB model, and the iOS Safari bug that silently disables HDR rendering if your image lives inside the wrong CSS container.
