A developer seeks to optimize sequential multi-agent LLM workflows (Architect → Coder → Debugger) on a single RTX 3090 (24GB VRAM) by achieving sub-2-second model swaps between system RAM and VRAM. Despite fast PCIe 3.0/4.0 hardware enabling high throughput, the primary bottleneck identified is software overhead from process and CUDA context re-initialization during model loading. The author requests community solutions, architectures, or forks that minimize this re-init latency for near-instant hot-swapping.
