FanControl.Releases

Rem0o/FanControl.Releases · ★ 21.1K

Fan Control is a highly customizable fan-controlling app for Windows: it drives your PC's CPU, GPU and case fans from temperature-based curves you design in a GUI.

LMCache

LMCache/LMCache · ★ 12.1K

LMCache is a KV cache management layer for LLM inference that turns the KV cache from a temporary, per-process state into reusable, persistent 'AI-native knowledge' that can be shared across serving engines, reducing time-to-first-token and boosting throughput for long-context, multi-turn, and RAG workloads.

julia

JuliaLang/julia · ★ 49.2K

Julia is a high-level, high-performance dynamic programming language built for technical and scientific computing, numerical analysis, and machine learning.

Betterfox

yokoffing/Betterfox · ★ 10.9K

Betterfox is a curated user.js file of about:config tweaks that makes Firefox more private, secure, and performant without installing third-party code.
