According to the manufacturer, Pangram 4 is six times larger than its predecessor and produces 14 times fewer false positives and six times fewer missed AI texts than Pangram 3.\n\nPangram 4 is also said to be able to distinguish between text that has been lightly polished by AI and text generated entirely by AI, and to be robust against tools designed to make AI-generated text sound more human: for 13 common \"humanizers,\" the model detects the AI component in 98.83 percent of cases.\n\nThe API costs $0.05 per 100 words, which, depending on the document length, corresponds to a price increase of two to ten times. In addition, all plans can now scan images at no additional cost. Pangram 3 will continue to be supported for two more months and will be shut down on September 30, 2026.\n\n```\nAI News Without the Hype – Curated by Humans\n\n\t\t\t\t\tSubscribe to THE DECODER for ad-free reading, a weekly AI newsletter, our exclusive \"AI Radar\" frontier report six times a year, full archive access, and access to our comment section.\t\t\t\t\n\n\t\t\t\t\tSubscribe now\n```\n\n[Pangram](https://www.pangram.com/blog/introducing-pangram-4)|\n\n[Model Card](https://www.pangram.com/research/model-card/pangram-4)", "url": "https://wpnews.pro/news/pangram-says-its-new-ai-text-detector-makes-only-one-mistake-per-24000-documents", "canonical_source": "https://the-decoder.com/pangram-says-its-new-ai-text-detector-makes-only-one-mistake-per-24000-documents/", "published_at": "2026-07-29 17:16:53+00:00", "updated_at": "2026-07-29 17:40:02.320930+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-products", "ai-tools", "ai-research"], "entities": ["Pangram", "Pangram 4", "Pangram 3"], "alternates": {"html": "https://wpnews.pro/news/pangram-says-its-new-ai-text-detector-makes-only-one-mistake-per-24000-documents", "markdown": "https://wpnews.pro/news/pangram-says-its-new-ai-text-detector-makes-only-one-mistake-per-24000-documents.md", "text": "https://wpnews.pro/news/pangram-says-its-new-ai-text-detector-makes-only-one-mistake-per-24000-documents.txt", "jsonld": "https://wpnews.pro/news/pangram-says-its-new-ai-text-detector-makes-only-one-mistake-per-24000-documents.jsonld"}}
