One engineer created a blackjack game for the fly-brain bets against a dealer.\n\nBut the fly’s success varies — like all gamblers — each time you run the experiment.\n\nOther users plugged the neural network into a variety of homemade robots, such as animatronic cats, crab-like walkers, and small drones.", "url": "https://wpnews.pro/news/fruit-fly-beats-advanced-ai-at-chess-in-just-11-moves-and-thats-just-the-start", "canonical_source": "https://nypost.com/2026/09/19/us-news/fruit-fly-beats-claude-opus-5-at-chess/", "published_at": "2026-09-19 13:28:18+00:00", "updated_at": "2026-09-19 13:54:58.246510+00:00", "lang": "en", "topics": ["artificial-intelligence", "neural-networks", "ai-research", "robotics"], "entities": ["HHMI Janelia Research", "Google Research", "Maxime Labonne", "Claude Opus 5", "Anthropic", "Stonkfly", "FlyJack", "Stanford University"], "alternates": {"html": "https://wpnews.pro/news/fruit-fly-beats-advanced-ai-at-chess-in-just-11-moves-and-thats-just-the-start", "markdown": "https://wpnews.pro/news/fruit-fly-beats-advanced-ai-at-chess-in-just-11-moves-and-thats-just-the-start.md", "text": "https://wpnews.pro/news/fruit-fly-beats-advanced-ai-at-chess-in-just-11-moves-and-thats-just-the-start.txt", "jsonld": "https://wpnews.pro/news/fruit-fly-beats-advanced-ai-at-chess-in-just-11-moves-and-thats-just-the-start.jsonld"}}
