Amazon has made significant changes to its artificial intelligence (AI) strategy, scaling back the development of several in-house Nova AI models. The company will continue to support existing customers with these models, but they will no longer receive active development. In contrast, Amazon is investing in a new research team, known as the Frontier Model Research group, which will focus on developing a new foundation model. This new model is set to be unveiled at the company's re:Invent conference later this year. The shift in focus highlights Amazon's ongoing efforts to advance its AI capabilities and improve its products and services.
