Worse, the open-weight model DeepSeek V4.1 Flash reaches 72.8 percent at a tenth of the cost. Because open models can no longer be restricted, analysts say the window for defenders is shrinking fast.\n\nThe article [The gap between open and closed AI models in cyber capabilities keeps shrinking](https://the-decoder.com/the-gap-between-open-and-closed-ai-models-in-cyber-capabilities-keeps-shrinking/) appeared first on [The Decoder](https://the-decoder.com).", "url": "https://wpnews.pro/news/the-gap-between-open-and-closed-ai-models-in-cyber-capabilities-keeps-shrinking", "canonical_source": "https://the-decoder.com/the-gap-between-open-and-closed-ai-models-in-cyber-capabilities-keeps-shrinking/", "published_at": "2026-11-07 15:35:50+00:00", "updated_at": "2026-11-09 01:28:24.535816+00:00", "lang": "en", "topics": ["ai-safety", "large-language-models", "artificial-intelligence"], "entities": ["OpenAI", "GPT-6 Sol Daybreak", "DeepSeek", "DeepSeek V4.1 Flash", "Vals AI", "The Decoder"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/the-gap-between-open-and-closed-ai-models-in-cyber-capabilities-keeps-shrinking", "markdown": "https://wpnews.pro/news/the-gap-between-open-and-closed-ai-models-in-cyber-capabilities-keeps-shrinking.md", "text": "https://wpnews.pro/news/the-gap-between-open-and-closed-ai-models-in-cyber-capabilities-keeps-shrinking.txt", "jsonld": "https://wpnews.pro/news/the-gap-between-open-and-closed-ai-models-in-cyber-capabilities-keeps-shrinking.jsonld"}}
