EfficientLLM: Efficiency in Large Language Models
Large Language Models (LLMs) have driven significant progress, yet their
growing parameter counts and context windows incur prohibitive compute, energy,
and monetary costs. We introduce EfficientLLM, a novel benchmark and the first
comprehensive empirical study evaluating efficiency techniques for LLMs at
scale. Conducted on a production-class cluster (48xGH200, 8xH200 GPUs), our
study systematically explores three key axes: (1) architecture pretraining
(efficient attention variants: MQA, GQA, MLA, NSA; sparse Mixture-of-Experts
(MoE)), (2) fine-tuning (parameter-efficient methods: LoRA, RSLoRA, DoRA), and
(3) inference (quantization methods: int4, float16). We define six fine-grained
metrics (Memory Utilization, Compute Utilization, Latency, Throughput, Energy
Consumption, Compression Rate) to capture hardware saturation,
latency-throughput balance, and carbon cost. Evaluating over 100
model-technique pairs (0.5B-72B parameters), we derive three core insights: (i)
Efficiency involves quantifiable trade-offs: no single method is universally
optimal; e.g., MoE reduces FLOPs and improves accuracy but increases VRAM by
40%, while int4 quantization cuts memory/energy by up to 3.9x at a 3-5%
accuracy drop. (ii) Optima are task- and scale-dependent: MQA offers optimal
memory-latency trade-offs for constrained devices, MLA achieves lowest
perplexity for quality-critical tasks, and RSLoRA surpasses LoRA efficiency
only beyond 14B parameters. (iii) Techniques generalize across modalities: we
extend evaluations to Large Vision Models (Stable Diffusion 3.5, Wan 2.1) and
Vision-Language Models (Qwen2.5-VL), confirming effective transferability. By
open-sourcing datasets, evaluation pipelines, and leaderboards, EfficientLLM
provides essential guidance for researchers and engineers navigating the
efficiency-performance landscape of next-generation foundation models.
