  Commenters on Hacker News largely discuss the accessibility and performance hurdles of running large language models (LLMs) locally, particularly Qwen-7B, on consumer hardware like MacBooks with Apple Silicon. Several express skepticism about the practicality of the "free" claim in the title, pointing to the significant time investment required for quantization and the limitations imposed by limited VRAM, resulting in slow inference speeds. Some highlight the trade-offs between different quantization methods, with GGML generally considered easier to use despite potentially being slower than GPTQ. Others question the real-world usefulness of running such models locally, given the availability of cloud-based alternatives and the inherent performance constraints. A few commenters offer alternative solutions, including using llama.cpp with Metal and exploring cloud-based options with pay-as-you-go pricing. The overall sentiment suggests that while running LLMs locally on a MacBook is technically feasible, it's not necessarily a practical or efficient solution for most users.

  The Hacker News post discussing running Qwen3 on a Mac with MLX generated several comments, exploring various aspects of the process and its implications.

  One commenter highlighted the potential cost savings of using MLX on a Mac compared to cloud-based GPU instances, suggesting it could be a more affordable way for individuals to experiment with large language models.
