Work
My focus is GeoSpatios and research on machine intelligence. This index collects the independent work around it: open-source tools, small utilities, and experiments in how people interact with software.
Research
Agent reasoning · ARC-AGI-3 · 2026
An ARC-AGI-3 agent harness that builds executable models of unfamiliar environments and tests them against observations. The essay walks through the design, evaluations, replayable traces, and failed approaches.
Model behavior · Text watermarking · 2026
An independent investigation of Anthropic’s disclosed text-watermark design. Reconstructs the mechanism and tests its behavior through controlled experiments with local models.
LLM routing · Evaluation · 2024
Co-authored research on choosing between language models with different capabilities and costs. Uses preference data to learn when a request benefits from a stronger model.
Earlier work
A terminal-style website template. Content, links, and appearance can be adapted through a single configuration file.
An open-source Markdown editor centered on the shared document, with real-time synchronization and a lightweight interface.
A browser extension that applies selective emphasis within words, exploring how typography changes the experience of reading.
Experiments
Reading with personal context.
An experiment in making summaries depend on the reader: their interests, background, and reason for opening a page. Citations connect the summary back to its source.
Keeping credentials on the device.
A macOS vault for API keys and one-time codes. The design keeps quick retrieval on the device, without making a hosted service part of the workflow.
Giving agents an explicit place to act.
An exploration of how an application can expose state and user-approved actions to an agent through a defined browser interface.
Gesture, sound, and visual feedback.
A browser instrument that maps hand movement to pitch and timbre. The accompanying patterns make the relationship between a gesture and its sound visible.
An everyday object as a musical interface.
A small experiment in physical interaction: moving a laptop lid controls sound, with waveform patterns as feedback.
