Control what your AI can see. LeanCTX (Lean Context) is the context intelligence layer for AI agents — one local Rust binary that decides what they read, remembers what they learn, guards what they touch, and proves what they save. 60–90% fewer tokens as the receipt. 76 MCP tools, 30+ agents, local-first.

ANEE is an experimental dynamic inference wrapper for pretrained Transformer language models (currently GPT-2). Instead of always running all layers, ANEE exposes an energy_budget and performs early exit inside the model’s forward pass.

Abseil is a common utility library for C++ that provides foundational building blocks for applications. It serves as a collection of optimized utility functions and data structures that augment the C++ standard library across different compiler versions. The library is distinguished by its high-performance containers, including SIMD-accelerated hash maps and sets for efficient key-value lookups. It also provides a comprehensive framework for computing absolute time points, durations, and timestamps across global time zones. The project covers a broad range of capability areas, including conc

Pulse is a generative model image upscaler and latent space image processor. It functions as a self-supervised photo upsampling tool that increases image resolution by exploring the latent space of pre-trained generative models to synthesize high-quality details. The system includes a face image alignment tool designed to standardize the scale and orientation of raw facial photos. This preprocessing utility prepares images for higher resolution processing by aligning and downscaling faces to a standard orientation. The project covers AI image super-resolution and generative photo upscaling,
