Consider a bounded pilot for compatible MoE inference workloads.

Why: Public tests demonstrate useful decoding performance and limited accuracy checks. Results depend on batch size, kernel implementation and precision layout; full-scale training and sustained operational performance require further qualification.
Next: Pin the model and Neuron versions, replay representative traffic, and measure output quality, tail latency, throughput and total operating cost before expanding.

Constraints

Custom NKI optimization and model-specific integration can require substantial engineering.
New serving plugins remain beta, while NxD Inference has entered maintenance and requires a migration plan.
Logical NeuronCore configurations currently support only LNC=1 or LNC=2.
Single-stream kernel gains can disappear at larger batches; mixed-precision layout conversions can offset compression benefits.
Current-stack correctness, sustained reliability and full-cluster performance need workload-specific qualification.
