OpenAIも信じていた“万能AIモデル神話”が崩壊　背景に3つの課題　次なる戦略は - ITmedia ビジネスオンライン

Additionally, the article notes that open-source AI expands the overall market rather than threatening commercial ventures, and while 2025 was called the "year of agents," fully autonomous agents remain distant from widespread adoption.
