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.

Benchmarking LLMs on Nonogram Solving
Read Full Article: Benchmarking LLMs on Nonogram Solving
A benchmark was developed to assess the ability of 23 large language models (LLMs) to solve nonograms, which are grid-based logic puzzles. The evaluation revealed that performance significantly declines as the puzzle size increases from 5×5 to 15×15. Some models resort to generating code for brute-force solutions, while others demonstrate a more human-like reasoning approach by solving puzzles step-by-step. Notably, GPT-5.2 leads the performance leaderboard, and the entire benchmark is open source, allowing for future testing as new models are released. Understanding how LLMs approach problem-solving in logic puzzles can provide insights into their reasoning capabilities and potential applications.
