Qwen
The official repo of Qwen (通义千问) chat & pretrained large language model proposed by Alibaba Cloud.
Project mention: Running Qwen, Nearly as Powerful as DeepSeek, on a MacBook Pro | dev.to | 2025-02-05Qwen (Qwen GitHub Repository) has been gaining attention recently as a powerful open-source large language model (LLM). I decided to give it a spin on my MacBook Pro using Ollama, a platform designed for running local LLMs. While Qwen2.5-Max boasts the highest performance, my setup could only handle the smaller Qwen2.5 (32B) model. Here's what I found!
