How Ray Serve's multiplexing routes per-tenant LoRAs to a shared base model efficiently.
9 min · Reviewed 2026
The premise
Ray Serve multiplexing keeps hot LoRAs on GPU and pages cold ones, serving many tenants from one base.
What AI does well here
Estimate per-tenant memory
Tune cache size and TTL
Monitor cold-load latency
What AI cannot do
Avoid base-model memory cost
Mix incompatible base architectures
Skip rate limits
