Libraries and experiments

CASK

LLM · KV cache

CASK studies KV cache compression during long LLM reasoning. It keeps answer-critical states and merges repeated intermediate states. Published on arXiv on April 13, 2026 (arXiv:2604.10900).

2026

Pylibkit

Swift · Python

A toolkit that combines SwiftPM templates, a Python CLI, and signing automation so Apple-platform projects can bundle Python runtimes and packages with less setup.

2025

zenz-coreml

Core ML · Swift

An on-device ML experiment that converts PyTorch models, including stateful KV-cache variants, to Core ML for memory-constrained iOS keyboard inference.

2024 - 2025

FloatingHUD

SwiftUI · HUD

A reusable pure-SwiftUI HUD package with draggable, edge-snapping compact and expanded states for metrics and debugging overlays.
