Amazon’s engineering guidance makes a clear distinction: using AI is not the same as producing value with it. In a memo circulated internally in September 2026 and published on October 27, Worldwide Amazon Stores vice president and distinguished engineer Terk Terkowitz describes a “Renaissance Developer” whose work is defined by outcomes, not by the tools used.13
What Amazon means by the “Renaissance Developer”
The memo describes developers who combine AI tools with human judgment and domain expertise to build new things. That framing does not make AI use a requirement for every task. Engineers should be able to explain when current AI tools do not benefit their work; Amazon’s guidance treats that assessment as “a finding, not a failing.”10
The emphasis is on understanding the problem, choosing appropriate tools, and delivering useful results—not demonstrating activity for its own sake. The memo also addresses software development managers, making the distinction relevant to how teams are supported and assessed.5

Why the memo warns against “tokenmaxxing”
“Tokenmaxxing” means maximizing AI token use as a visible sign of adoption. Amazon warns against treating token counts, adoption rates, code changes, reviews, or lines of code as stand-alone measures of engineering productivity. Those figures record inputs or activity; they do not, by themselves, show whether customers or the business benefited.7

The warning also connects to Amazon’s leadership principles. The memo’s reported framing is that tokenmaxxing conflicts with Frugality, while measuring lines of code conflicts with Invent and Simplify: encouraging more consumption or more code can add cost and complexity without showing that the work became more valuable.11

This is not the same as saying adoption data has no use. Reporting on the memo says Amazon acknowledges that usage measures can correlate with results, but says they should be handled with care and judgment.16 A correlation may make a metric useful as a signal to investigate; it does not make the metric a sound target. If a team is rewarded for increasing token use, it can increase that number without necessarily improving the work.
What managers should learn from adoption extremes
The guidance calls for closer study of teams near both the 10th and 90th percentiles of AI adoption.16 That does not mean assuming that the least-adopting teams are behind or that the most-adopting teams are doing best. Adoption figures are a starting point for questions, not a verdict.
For teams using AI less, managers can examine whether the work is a poor fit for current tools, whether teams face barriers, or whether useful opportunities are being missed. For teams using it heavily, they can look at whether that use improves outcomes or simply raises activity and cost. These are practical questions for interpreting the extremes, not a substitute for the memo’s central standard: assess the value of the work.
The practical takeaway for engineering teams
Amazon’s guidance is not an instruction to avoid AI or to define success by a fixed amount of AI use. It asks engineers to apply judgment, draw on their domain knowledge, and focus on customer and business results. It asks managers to use adoption measures carefully rather than turning them into scorecards.16
The distinction is straightforward: AI usage is an input; useful engineering outcomes are the goal. When AI does not help a particular task, explaining why can help a team understand where the tools fall short—without pressuring engineers to manufacture usage.10
