Reliably Incorrect: Notes and visualizations on the agent capability threshold — when LLM agents stop being reliably wrong and start being occasionally right.
λ-bench variance: Five Sonnet 4.6 runs on the same LamBench task, classified by Opus 4.6, rendered as flame charts — what variance looks like when you stop averaging it away.

intercept: Turn any website into a typed JSON API using self-improving agents.
agent-tuning: Using recursion to achieve predictable agent output.
doomberg-terminal: A Chrome extension that performs algorithmic trading using Robinhood's web interface and market data.
alphadidactic: An iterative research agent: searches academic research, applies it to time-series data, and probes it to find novel discoveries.
