Hacker News1 DeepSeek-v3.1DeepSeek-V3.1 introduces hybrid inference with Think and Non-Think modes, offering faster processing and improved agent capabilities. The update includes enhanced tool usage, API improvements, extended context support, and better reasoning abilities. The model features open-source weights and updated pricing starting September 2025. Benchmarks and model performance: Discussion about various benchmarks like tbench.ai, with debate over their reliability and usefulness. Many users argue benchmarks are flawed and real-world testing is more valuable. Mixed views on how DeepSeek V3.1 compares to other models.Technical requirements and implementation: Detailed discussion of RAM/VRAM requirements, quantization options, and running the model locally. Focus on making the model work with different hardware setups and optimizing performance through various configurations.Tool usage formats: Concerns about the model's inconsistent tool call formats, sometimes using outdated XML-style formats instead of standard JSON. Discussion of API compatibility and function calling capabilities across different models.
Reddit science1 Using 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
