An open-source toolkit for AMD Ryzen 5700G integrated GPU users, supporting LLM inference on Vega8 APU via ROCm and Vulkan, and providing a dual-GPU collaborative management solution
Section 01
This open-source toolkit targets AMD Ryzen 5700G Vega8 APU users, enabling LLM inference via ROCm and Vulkan. Key features include dual GPU collaborative management, integration with llama.cpp and LM Studio, and optimizations for resource-constrained APU hardware, aiming to let AMD APU users run LLMs locally without discrete GPUs.
Section 02
With LLM popularity, local runs are desired, but NVIDIA's CUDA dominates AI inference. AMD users—especially those with integrated GPUs (APUs)—face barriers. This toolkit was created to solve this, focusing on the Ryzen 5700G's Vega8 APU to enable local LLM experiences for users without independent GPUs.
Section 03
ROCm & Vulkan Dual Backend: Supports AMD's ROCm (CUDA-like compute platform) and Vulkan (cross-platform compute API for broader driver compatibility). Dual GPU Management: Dynamic device selection, mixed inference (layer allocation across GPUs), unified memory pool. Integrated Frameworks: Optimized llama.cpp (high efficiency) and LM Studio (GUI extension to AMD APU).
Section 04
Vega8 Challenges: 8 compute units, 512 stream processors, shared memory (bandwidth bottleneck), limited parallelism, experimental ROCm support. Optimizations: 4/8-bit quantization (reduce memory/bandwidth), layer pipeline (CPU-GPU collaboration), KV cache prefetch/caching (predictive loading).
Section 05
Edge Deployment: Smart home control centers (local voice assistants), offline document processing (summary/translation/QA), education demos (low-config hardware). Development: Model compatibility testing, inference optimization experiments, multi-GPU load balancing research.
Section 06
Current Limits: Max 7B model support (Vega8 memory constraint), slower inference (vs NVIDIA high-end), complex ROCm setup. Future Plans: Expand to more Ryzen APU models (5000G/7000 series), Windows support, MLIR/IREE compiler integration, distributed multi-APU inference.

Nornir MCP Server is an enterprise-level server based on the Model Context Protocol (MCP). It seamlessly integrates large language models (such as Claude) with the Nornir network automation framework, supporting natural language orchestration for multi-vendor network devices (Cisco, Arista, Juniper, etc.), and providing production-grade features like a dual-engine architecture (NAPALM + Netmiko), intelligent filtering, and a secure sandbox.
Bibliothèque Française LLM is a structured indexing and annotation project for French public domain literature designed specifically for large language models (LLMs). It integrates multiple authoritative sources such as DraCor, Common Corpus, and Wikisource, providing metadata indexing categorized by genre, author, and era, as well as in-depth annotations for dramatic texts (including characters, lines, stage directions, etc.). Its aim is to enable LLMs to efficiently read and understand classic French literary works.
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.
