Someone built a multi-GPU homelab for local AI inference using a Framework Desktop, RTX 5090 eGPU, and two DGX Spark units, routing requests between local and cloud models depending on latency needs. They're currently at 60-70% local inference and plan to move toward 100%, though they admit the eGPU was a mistake and you don't need this much hardware to start.

• The Qwen 3.8 27B model on the 5090 eGPU hits 150+ tokens/second for fast inference, while the Deepseek v4 Flash models on the DGX Sparks handle slower but higher-quality batch processing and background jobs.
• A custom routing plugin (Arch-Router) decides whether each request goes to local models or cloud/frontier models based on latency requirements, currently keeping about 60-70% of workloads local.
• The hardware stack is overkill for most people—started with just a Mac mini and kept adding. The eGPU specifically isn't worth the investment.

Meta open-sourced Muse Glimmer, a 30-billion-parameter model designed to run on consumer GPUs and laptops for local AI agent tasks like scheduling, coding, and tool use. The model uses quantization and speculative decoding to fit within 20-32GB of memory while maintaining speed for real-time interaction. It's available now under Apache 2.0 license with integrations for llama.cpp, MLX, and other frameworks.

• Meta open-sourced Muse Glimmer, a 30B-parameter agentic model quantized to under 20GB so it runs locally on consumer GPUs/laptops (24-32GB) while competing with Gemma 4-31B and Qwen 3.6-27B.
• Speculative decoding with a lightweight drafter model proposes token blocks at once instead of one token at a time, speeding up reasoning and tool calls without changing outputs.
• Training combined logit distillation from a larger teacher model, agent-heavy mid-training data, and post-training RL/distillation across reasoning, coding, and agentic tasks.
• Released under Apache 2.0 with upcoming llama.cpp, MLX, and ExecuTorch integrations and support from Ollama, LM Studio, Together AI, and chipmakers like NVIDIA, Intel, AMD, and Arm.
