Vertical orientation, touch gestures, responsive props, imperative API, and 9 bug fixes — all in one major release.

Intelligence Engineered: Why AI Success Demands a New Approach to Enterprise Data

Artificial intelligence has moved from the laboratory to the boardroom with astonishing speed. Machine learning models now write code, design molecules, and optimize supply chains. The promise is real and well documented. Yet beneath the headlines, a quieter story is unfolding across industries. Most enterprises are struggling to move AI beyond the pilot phase. They have the algorithms. They have the cloud infrastructure. What they consistently lack is a data foundation capable of supporting int
