Amazon wants 80% of its developers to use AI for coding at least once a week, but there’s one condition

Amazon is pushing hard to make AI-assisted coding an everyday habit across the company. The target is clear—80 per cent of developers should be using AI for coding tasks at least once a week, according to the Financial Times. But the company isn’t leaving the choice of tool up to its engineers. It wants them on Kiro, its in-house AI coding assistant that launched in July 2025, and it’s actively discouraging everything else.

An internal memo viewed by Reuters last November laid it out plainly: “We do not plan to support additional third-party AI development tools.”
