Serving

LoRA serving

What it is

LoRA serving applies low-rank adapter updates to a shared base model during inference. Multiple adapters can reuse the base weights while adding adapter-specific matrix work.

Why it moves cost and latency

Adapter reuse avoids loading a full model copy for every specialization. Adapter memory, switching, batching compatibility, and added operations still affect capacity and latency.

What it looks like in practice

Servers load or cache adapters, verify their base-model compatibility, and route requests to the correct identity. Operators measure cache misses, adapter churn, and mixed-adapter batch efficiency.
