According to Reuters, on 26 November, an internal aide-mémoire was issued in Amazon demanding that engineers give priority to self-study by the company AI coding toolsKiro, not a third-party product。
The memorandum states that Amazon will no longer support the new third-party AI development tool, which means that hot tools such as OpenAI 'Codex', Anthropic 'Claude Code' and Creative Cursor will be excluded from the recommendation。
It is worth noting that, despite the fact that Amazon has invested approximately $8 billion in Anthropic and has signed a seven-year, $38 billion cloud service agreement with OpenAI, the company has chosen to give priority to Kiro in its internal development。
Kiro was officially launched in July of this year as a natural language-driven code generation tool to help developers quickly build websites and applications. The tool relies in part on the technical version of Anthropic, but does not directly use Claude Code. Last week Amazon extended the use of Kiro to the world and synchronized the new functionality。
This internal policy was signed by Peter DeSantis, Senior Vice President of AWS, and Dave Treadwell, Senior Vice President of Electric Infrastructure, emphasizing that "Kiro will be an AI primary development tool recommended by Amazon"。
Previously, Amazon had labeled Codex "Do not use Do Not Use" in an internal file, and Claude Code had been added to the same list at one time and was withdrawn for external challenge。
