Multi-LoRA Serving
Serving many LoRA fine-tunes from one shared base model by loading each request's small adapter on demand, instead of deploying a separate full model for every task or customer.
In depth
Serving many LoRA fine-tunes from one shared base model by loading each request's small adapter on demand, instead of deploying a separate full model for every task or customer. Systems like S-LoRA keep adapters in host memory and page the active ones onto the GPU. They also batch requests that use different adapters together with custom kernels. The S-LoRA paper reports serving thousands of adapters on a single GPU, which makes per-tenant fine-tuning practical to host.
