A new research paper demonstrates that advanced language models like GPT-5.5 and Claude Opus 4.7 can significantly reduce the detectability of AI-generated text. In an agentic research setup, these models closed 71-75% of the style gap compared to human authors on post-editing tasks, outperforming human edits. The study also explored an AI-text detection arms race, finding that frontier LLMs can efficiently lower their detection probability against known detectors with moderate effort. AI
