• Hacker News1How to run Qwen 3.5 locallyThis guide explains how to run Alibaba's new Qwen3.5 language models locally on your device. The model family includes various sizes from 0.8B to 397B parameters, supporting 256K context across 201 languages with thinking and non-thinking modes. The guide provides specific instructions for different model sizes, memory requirements, and setup using llama.cpp, with options for CPU or GPU inference depending on your hardware capabilities.Local model performance:Users report impressive performance running Qwen 3.5 models locally, with 100 tok/s on consumer GPUs. Discussion covers speed comparisons, hardware requirements, and quality trade-offs between different model sizes and quantization levels.Hardware and quantization choices:Extensive debate on choosing between fewer parameters with less quantization vs more parameters with higher quantization. Users share specific configurations for different GPUs and memory constraints.Coding capabilities and limitations:Mixed experiences with local models for coding tasks. While some report good results with simple tasks, others note limitations with complex coding, hallucinations, and need for human oversight compared to commercial models.
• Reddit science1Using scented products indoors changes the chemistry of the air, producing as much air pollution as car exhaust does outside, according to a new study. Researchers say that breathing in these nanosized particles could have serious health implications.Using scented products indoors, such as flame-free candles and wax melts, can create significant indoor air pollution comparable to car exhaust. Research by Purdue University found these products release nanosized particles that can penetrate deep into lungs and potentially enter the bloodstream, posing serious respiratory health risks.Misleading title scope:Discussion about how study only focused on wax melts but title suggests all scented products, with debate about whether findings could logically extend to other scented itemsHealth concerns from chemist:A chemist's perspective against using scented products leads to sharing of personal health impact stories, from COPD to cancer cases, and debate about necessity of artificial scentsAir purification solutions:Discussion of HEPA filters and other air purification methods as solutions, with debate about effectiveness against different types of pollutants like VOCs and nanoparticles
