With the fast (no-think) route, gate-selection latency is now proportional to the
ANSWER length (a no-think model runs ~10-13 tok/s), not hidden thinking. A verbose
"reasoning" field pushed a selection to ~9s (over the 8s budget). Request compact
JSON with a <=8-word reasoning → ~2s (vs ~9s prose, or ~1.2s with no reasoning).
Validated live against vllm-fast (glm-4.6-reap-fast): 2.0s, valid selection JSON,
zero reasoning tokens.
