reasoning keeps its 2 GPUs untouched. verifier's freed GPU goes to a second ornith replica instead of a standalone qwen-only pod -- both replicas load ornith:35b + qwen2.5:3b-instruct, k8s Service load-balances across them, so 2 concurrent implementer-style calls get independent instances.

# Kong reads its timeouts from the Kubernetes Service, not the Ingress —
|
|
# Ingress annotations configure Route entities (strip-path, methods,
|
|
# plugins), these configure the Service entity. They were on
|
|
# llm-chat-ornith's Ingress and therefore ignored, leaving Kong's 60s
|
|
# default in force. KServe propagates InferenceService annotations to the
|
|
# Service it generates, which is how they reach Kong from here.

# This was invisible while OLLAMA_KEEP_ALIVE=-1 kept the model resident: no
|
|
# request ever waited on a cold load. A pod restart flushes VRAM, and
|
|
# loading ornith:35b takes longer than 60s, so the first request after any
|
|
# restart returned 504.
