• Hacker News1The last six months in LLMs, illustrated by pelicans on bicyclesA keynote speaker reflects on recent developments in AI models over six months, discussing various models' capabilities, pricing, and performance, particularly highlighting their attempts to generate images of pelicans riding bicycles as a unique benchmark test.Successful product launch:Discussion of ChatGPT's image generation feature's massive success with 100M new users in a week, including viral "Ghibli-style" images, while noting some users remained unaware of its impact despite its mainstream adoption.Pelican benchmark:Debate about using "pelican riding bicycle" SVG generation as AI benchmark, discussing methodology issues like single-sample testing, determinism, and how benchmark tests get optimized away once they become known to AI companies.Model memory concerns:Discussion of privacy and safety implications of AI models' increasing context windows and memory capabilities, including concerns about uncontrolled context and potential dangers as models gain access to more data and tools.
• 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
