Read Full Article: Benchmarking 4-bit Quantization in vLLM
A comprehensive analysis of vLLM quantization methods reveals varied performance across different techniques. Marlin achieved the highest token processing speed at 712 tokens per second, significantly outperforming the baseline FP16's 461 tok/s, while GPTQ without Marlin's kernel lagged behind at 276 tok/s. BitsandBytes maintained the smallest quality drop and required no pre-quantized weights, whereas GGUF had the worst perplexity but excelled in HumanEval scores. AWQ showed unexpectedly slow performance in vLLM, processing only 67 tok/s. Understanding these differences is crucial for optimizing model efficiency and performance in machine learning applications.

Llama.cpp vs Ollama: Code Generation Throughput
Read Full Article: Llama.cpp vs Ollama: Code Generation Throughput
A notable performance discrepancy has been observed between llama.cpp and Ollama in terms of code generation throughput when running the Qwen-3 Coder 32B model locally. The analysis reveals that llama.cpp achieves approximately 70% higher throughput compared to Ollama, despite both using the same model weights and hardware. Potential reasons for this difference include variations in CUDA kernels, attention implementations, context or batching defaults, scheduler or multi-GPU utilization, and overhead from Ollama's runtime or API layer. Understanding these differences is crucial for optimizing performance in machine learning applications. This matters because optimizing code generation throughput can significantly impact computational efficiency and resource utilization in AI model deployment.

Benchmarking SLMs on Modest Hardware
Read Full Article: Benchmarking SLMs on Modest Hardware
Benchmarking of SLMs (Statistical Language Models) was conducted using a modest hardware setup, featuring an Intel N97 CPU, 32GB of DDR4 RAM, and a 512GB NVMe drive, running on Debian with llama.cpp for CPU inference. A test suite of five questions was used, with ChatGPT providing results and comments. The usability score was calculated by raising the test score to the fifth power, multiplying by the average tokens per second, and applying a 10% penalty if the model used reasoning. This penalty is based on the premise that a non-reasoning model performing equally well as a reasoning one is considered more efficient. This matters because it highlights the efficiency and performance considerations in evaluating language models on limited hardware.
