Amazon struggles to replace rival AI with in-house Nova models

Amazon faced internal challenges as it attempted to replace rival technologies with its own Nova AI models. Employees reportedly referred to the proprietary tools as “Amazon Basics” and relied on Anthropic for complex applications like the Kiro coding assistant and Rufus shopping chatbot. Executives restructured the division under Peter DeSantis and instructed teams to focus on post-training after engineers found the in-house technology struggled to match the performance of competitors.
