• Hacker News1Claude Opus 4.7Claude Opus 4.7 is now generally available with significant improvements in advanced software engineering, handling complex coding tasks with better autonomy and consistency. The model features enhanced vision capabilities for higher resolution images and produces more creative professional work. It includes new cybersecurity safeguards and is available across all Claude products at the same pricing as Opus 4.6. Early testers report major gains in coding accuracy, multi-step workflows, and long-running tasks, with some benchmarks showing 13% improvement over the previous version.Adaptive thinking and quality degradation:Users report confusion with new "adaptive thinking" feature and perceive Claude 4.6/4.7 quality drops. Many disable adaptive thinking and increase effort levels to restore baseline performance, while Anthropic's internal evaluations show different results.User migration to OpenAI Codex:Significant discussion about users switching from Claude to OpenAI's Codex due to perceived performance issues and usage limit frustrations. Mixed experiences reported, with some finding Codex inferior while others praise its consistency and speed.Cybersecurity restrictions and safeguards:Opus 4.7 introduces enhanced cybersecurity filters that block legitimate security research and bug bounty work. Users report excessive "malware" warnings even for their own code, forcing many to switch models or seek verification.
• 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
