An open-source tool designed specifically for macOS, offering local inference, performance benchmarking, and model evaluation for large language models (LLMs), simplifying LLM workflows on Apple Silicon devices.
Section 01
Kepler is an open-source tool designed specifically for macOS, integrating three core functions: model inference, performance benchmarking, and model evaluation. It addresses pain points such as scattered LLM tools, insufficient optimization, and inconsistent user experience on Apple Silicon devices, providing developers with a local, privacy-friendly LLM workflow.
Section 02
When running LLMs on macOS, developers face challenges like scattered tools (needing multiple tools for inference, evaluation, and benchmarking), insufficient optimization for Apple Silicon (mainstream frameworks lack Metal/Neural Engine support), inconsistent user experience (varying command-line parameters), and local privacy requirements (reluctance to upload data to the cloud). Kepler fills this gap with an "all-in-one" concept.
Section 03
Kepler offers three core modules:
Section 04
Kepler is built on llama.cpp (written in C/C++, using Metal to optimize Apple GPUs) at its core; the main interaction is via CLI (following Unix philosophy, easy to script); it has built-in model management features, supporting GGUF quantized model downloads from Hugging Face.
Section 05
Applicable Scenarios: Model selection comparison, local prototype development, hardware performance evaluation, educational research. Comparison with other tools:
Section 06
Installation Methods: Homebrew or source code compilation; Usage Steps: Download GGUF model → Run inference → Execute evaluation (see README for details). Kepler is an open-source project under the MIT license, with code hosted on GitHub (thisisadityapatel/kepler). Community contributions are welcome.
Section 07
Current Limitations: Only supports GGUF format, no distributed inference, lacks optimizations like speculative decoding. Future Plans: Add support for more model formats, improve evaluation suites, and explore graphical interfaces.
Section 08
Kepler integrates inference, evaluation, and benchmarking to address pain points of LLM tools on macOS, providing an efficient local solution for AI developers in the Apple ecosystem. As Apple Silicon becomes more prevalent in the AI field, such tools will grow in importance.

Splinter is a minimalist, high-performance key-value (KV) and vector storage system enabling zero-latency inter-process communication via shared memory and atomic operations. With only 766 lines of core code, it supports millions of operations per second and 768-dimensional vector storage, offering a new architectural approach for local LLM inference and data-intensive applications.
Folkering OS is the world's first AI-native bare-metal operating system, entirely written in Rust no_std without relying on Linux, POSIX, or libc. It can generate commands from scratch, compile them into WASM, and run them in 10 seconds, achieving true self-evolution.
This project explores how to use Large Language Models (LLMs) to detect logical vulnerabilities in Ethereum smart contracts, especially business logic flaws that are difficult for traditional static analysis tools to capture, such as economic manipulation and execution order errors.
This article introduces an open-source project for building modern large language models from scratch. The project evolves from a GPT-2-style basic architecture to a Llama 2/3-style production-level implementation, covering complete tutorial implementations of key technologies such as RMSNorm, RoPE, SwiGLU, GQA, and MoE.
