Amazon Pushes Engineers to Adopt Proprietary Kiro System, Moves Away from Competing AI Tools
Amazon has instructed its software engineers to begin using Kiro, the company’s in-house AI development platform, in a strategic move to compete more aggressively with industry leaders OpenAI and Google. The internal memo, reviewed by Reuters, signals a shift away from popular third-party AI tools such as OpenAI’s Codex, Anthropic’s Claude Code, and Cursor.
Signed by senior AWS and e-commerce executives Peter DeSantis and Dave Treadwell, the memo was posted on Amazon’s internal news site. It emphasizes that while existing tools will continue to be supported, the company does not intend to integrate additional third-party AI development platforms.
This directive is notable because Amazon has invested roughly $8 billion in Anthropic and secured a multiyear, $38 billion cloud deal with OpenAI. Despite these partnerships, the company is now signaling that internal development using Kiro will be the priority for its engineers.
Industry analysts suggest the move is part of Amazon’s effort to counter growing perceptions that it lags behind competitors like OpenAI and Alphabet’s Google in cutting-edge AI innovation. By pushing its workforce toward Kiro, Amazon aims to strengthen its proprietary AI ecosystem and maintain control over its software development tools.
An Amazon spokesperson confirmed the authenticity of the memo to Reuters.
