to the evaluation results from the publishers, Nex-N2.5-mini is the lightest model in the family, and its scores tend to be generally lower compared to the higher-tier Pro and Max models as well as large models from other companies. On the other hand, it demonstrates solid performance in certain tasks, scoring 73.4 on Terminal-Bench 2.1 and 83.4 on BrowseComp. In multimodal benchmarks such as OSWorld-Verified and OmniDoc, while its numbers are lower than the Pro model in the family and other models, it maintains a certain standard.<\/p>\n<h2>Strengths and Use Cases<\/h2>\n<p>It is built with a focus on operating as an agent for computer operations, web browsing, and visual grounding. A key characteristic is that it utilizes vision not merely as an input modality, but as a critical interface for perceiving the environment, verifying results, and progressing through tasks.<\/p>\n<p><!-- lmw:hardware --><\/p>\n<h2>Hardware Requirements<\/h2>\n<p><strong>Estimated requirements (calculated by Local Model Watch)<\/strong> \u2014 35.1B parameters<\/p>\n<div class=\"lmw-table-scroll\" tabindex=\"0\" style=\"overflow-x:auto;-webkit-overflow-scrolling:touch;max-width:100%;\">\n<table style=\"width:max-content;min-width:100%;border-collapse:collapse;\">\n<thead>\n<tr>\n<th>Your VRAM<\/th>\n<th>Quantization<\/th>\n<th>File size<\/th>\n<th>Est. memory needed<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>16GB (RTX 5060 Ti 16GB \/ 4060 Ti 16GB, etc.)<\/td>\n<td>Q2_K<\/td>\n<td>12.9GB<\/td>\n<td>15.5GB<\/td>\n<\/tr>\n<tr>\n<td>24GB (RTX 4090 \/ 3090, etc.)<\/td>\n<td>Q4_K_S<\/td>\n<td>19.5GB<\/td>\n<td>23.4GB<\/td>\n<\/tr>\n<tr>\n<td>32GB (RTX 5090, etc.)<\/td>\n<td>Q5_K_M<\/td>\n<td>25.1GB<\/td>\n<td>30.2GB<\/td>\n<\/tr>\n<tr>\n<td>48GB (RTX 6000 Ada \/ A6000, etc.)<\/td>\n<td>Q8_0<\/td>\n<td>34.4GB<\/td>\n<td>41.3GB<\/td>\n<\/tr>\n<tr>\n<td>80GB class (A100 \/ H100)<\/td>\n<td>BF16<\/td>\n<td>64.6GB<\/td>\n<td>77.5GB<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p><strong>Inference engine support<\/strong> (architecture name matched against each project&#8217;s own model registry in its source code, checked 2026-09-18): llama.cpp: registered, vLLM: registered, MLX (mlx-lm): registered.<\/p>\n<p><em>Memory estimates add a 20% runtime overhead (KV cache, etc.) to the actual size of the distributed files.
