   1389|LiteLLM sits in front of your three Ollama instances and presents a single OpenAI-compatible API at `http://litellm:4000`. It handles:
   1390|
-  1391|- **Model routing** — requests for `qwen3:32b` go to ROCINANTE, `qwen2.5:14b` goes to PD, `phi4` goes to N.O.M.A.D.
-  1392|- **Failover** — if ROCINANTE is offline, LiteLLM can fall back to PD automatically
-  1393|- **Load balancing** — distribute requests across instances running the same model
+  - **Model routing** — current reliable default is N.O.M.A.D.-local Ollama for background/automation paths, with PD kept available for shared light-tier use and Rocinante treated as optional/manual heavy capacity.
+  - **Failover** — avoid designs that require Rocinante to be online; degrade to N.O.M.A.D.-local or explicitly operator-invoked PD paths instead of automatic dependence on a personal PC.
+  - **Load balancing** — distribute requests across instances running the same model when you have multiple dependable backends, but do not assume Rocinante qualifies as one.
   1394|- **Usage tracking** — logs token counts, latency, and costs per model/user via its built-in database
