An experimental file compression method using an overfitted transformer and arithmetic coding to memorize and compress individual files.

A novel approach to file compression that achieves high ratios (e.g., 100MB CSV to 7MB) by training a small transformer to 'memorize a single file and predict the next byte.'

This experiment demonstrates a specialized, high-ratio file compression technique with significant B2B potential, despite its current performance limitations. The ability to compress a 100MB CSV to 7MB is compelling for industries dealing with large, repetitive datasets, such as financial logs, s...

The Weave Router, an intelligent model router for coding agents (e.g., Claude Code, Codex, Cursor) that dynamically selects the optimal LLM for inference requests.

Intelligently sends requests to the best model to serve them, reducing AI inference costs ('saved 40% on tokens') without sacrificing quality or velocity. It acts as an Anthropic/OpenAI endpoint for coding agents.

The Weave Router addresses a critical enterprise challenge: managing escalating LLM inference costs while maintaining performance for AI coding agents. By intelligently routing requests to cheaper, faster models for routine tasks and frontier models for complex ones, it delivers a tangible 40% co...

Git-lazy-mount, a tool that allows mounting a Git repository without fully cloning it, fetching files only when needed, inspired by Google3's monorepo approach. It includes `sgrep` for remote code search.

Enables 'google3 style repo clones work with Git,' making it 'super useful for very large repos that need to be cloned for AI coding sessions' by keeping 'microVMs... lean and start up much faster.' It works with 'normal Git commands.'

Git-lazy-mount addresses a critical developer pain point in large-scale software development and AI-assisted coding: the overhead of managing massive monorepos. By enabling 'lazy' fetching of files, it significantly reduces the startup time and resource consumption of development environments, pa...
