In a test where the agent was asked to identify a shape that didn’t match the others displayed, it couldn’t even decide which image to select. Instead, it repeatedly went over the same images and questioned its own conclusions.\n\n“Actually hmm, wait,” it said in its chain-of-thought transcript, later adding “Ugh,” because we’ve decided that we need to inject human mannerisms into these machines for some reason. The whole thing took so long that the agent eventually realized that the challenge had expired and it would have to start the process again...", "url": "https://wpnews.pro/news/are-ais-still-struggling-with-captchas", "canonical_source": "https://www.schneier.com/blog/archives/2026/09/are-ais-still-struggling-with-captchas.html", "published_at": "2026-09-18 11:05:52+00:00", "updated_at": "2026-09-18 11:25:09.888959+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-agents", "large-language-models", "ai-safety"], "entities": ["Anthropic", "Claude", "Gizmodo"], "alternates": {"html": "https://wpnews.pro/news/are-ais-still-struggling-with-captchas", "markdown": "https://wpnews.pro/news/are-ais-still-struggling-with-captchas.md", "text": "https://wpnews.pro/news/are-ais-still-struggling-with-captchas.txt", "jsonld": "https://wpnews.pro/news/are-ais-still-struggling-with-captchas.jsonld"}}
