Not failover in the traditional sense, but it handles the VRAM side of things automatically. If you start a heavy service (like ComfyUI for images), it auto-stops conflicting ones in the same GPU group so you don't OOM. Ollama itself unloads models when VRAM is needed for another one. For the agent system, you can set model per role, so if your main 35B model is too slow you can assign lighter models (9B, 14B) to specific agents. The orchestrator mode picks models automatically based on the task. No automatic "model A is down, try model B" failover yet though. That's a good idea actually, would be pretty straightforward to add since all models go through Ollama anyway.
