Amazon has taken a strategic step to prioritize the internal promotion of its proprietary AI coding tool, Kiro, while imposing restrictions on employees' usage of third-party solutions like Claude Code. Despite Amazon's significant stake in Anthropic and its role in facilitating the consumer market access for Anthropic's models and products, staff members are barred from utilizing Claude Code in real-world production settings without prior authorization.

Kiro, an AI coding tool developed in-house by Amazon and based on the technology similar to Claude, is designed to seamlessly integrate with Amazon's proprietary ecosystem, including its cloud services. This move has stirred up a debate within the company, with employees involved in the sale of third-party AI services voicing their puzzlement, and engineers engaging in discussions about the potential extremity of this policy.

Some employees argue that Claude Code outperforms its counterparts in certain aspects, and mandating the exclusive use of Kiro could potentially hinder the pace of development.
