Virtualized Module
Isolates PEFT modifications and supports multiple adapters on a shared base model, enabling flexible instance-level migration and seamless adapter management. This prevents chaotic model configurations and supports dynamic loading/unloading.
SMLM Kernel
The Segmented Multi-LoRA Multiplication (SMLM) kernel optimizes computation flow by merging fine-tuning and inference paths in forward propagation. This enables efficient batching and minimizes kernel invocation overhead, outperforming traditional sequential processing for multiple LoRA adapters.
Unified Computation Flow
A streamlined flow that handles both fine-tuning and inference requests within a shared runtime. It supports four types of requests: fine-tuning, evaluation, prefilling, and decoding, allowing joint forward and backward passes without cross-interference.

Case Study: Real-world Workload Adaptability
Loquetier demonstrates strong adaptability to real-world workloads, achieving 92.37% SLO attainment in a simulated environment using data from the BurstGPT dataset. It adaptively adjusts efficiency to prioritize quality of service during throughput spikes and recovers gracefully when loads decrease. This shows its robustness in dynamic, high-demand scenarios, unlike baselines that fail under similar stress.
Highlight: 92.37% SLO attainment under dynamic real-world workloads.
