Claude Opus 5.5 uses 95% fewer em dashes but longer answersArena analysis shows Anthropic's Claude Opus 5.5 reduced telltale AI writing patterns versus Opus 5: em dashes fell from 15.2 to 0.8 per 1,000 words (about 95% fewer), semicolons from 6.10 to 1.64, and average sentence length from 12.14 to 10.03 words, though answers grew from 453 to 481 words.
Study: LLM watermarking shifts refusals and tool callsAnthropic will embed invisible watermarks based on Google DeepMind's SynthID-Text in future Claude models. A study finds watermarking alters token sampling, causing 'sampling drift' that changes model refusals and agent tool calls, with effects varying by model and key. The findings matter for EU AI Act Article 50(2) compliance and AI safety.
How AI is Transforming the Future of War: 'Whoever Wins AI, Wins'The article notes AI is being rapidly integrated into militaries globally for battlefield awareness, training, surveillance, target identification, and unmanned vehicles.
