Metal Sandbox squeezes idle GPUs

🔥 What happened Researchers from SJTU and Microsoft released "Metal Sandbox," open-source infrastructure that runs GPU coding agents in isolated workspaces across networked Mac minis and schedules their commands across nodes. 💡 Why it matters On four M4 Mac minis, command throughput jumps 1.68x to 2.05x; with 16 sessions per node, estimated sustained throughput hits 2.14x. GPUs previously sat idle between model calls and compilation — the scheduler reclaims exactly that dead time. ⚡ Our take Apple Silicon just became a real agent cluster — not via new chips, but via smarter scheduling.
