Pushing LLMs to the edge of what a single MacBook can do.

Independent researcher / engineer. I work on local-first AI on Apple Silicon — paper reproduction, optimizer studies, KV cache quantization, and the tooling that actually makes it all run.

If it can be done on a MacBook, I want to know exactly how well.

gpt2-from-scratch — Rebuilt GPT-2 Small (124M) end-to-end on a MacBook Air M5. 1B FineWeb tokens, AdamW vs Muon, MLX port at 98% wall-clock efficiency, 9.14× KV cache compression with Δ PPL < 1.05. No cloud.

qjl-mlx — First MLX / Apple Silicon native port of QJL & TurboQuant (Google Research). Parity vs PyTorch reference to 1.79e-7 across 4 mode×codebook configs.

minimind-autoresearch — 17 autonomous ablations on a 26M Chinese LLM in 40 minutes. Muon beats best AdamW config by 23.8% val_loss on M5 MPS.

docflow — Fully local multi-format RAG. 100% offline, zero telemetry, retrieval Recall@5 = 1.0 on internal eval.

git-dungeon — A roguelike where your git commits are the monsters. CLI, Python, just for fun.
