THE CRUNCH
Amazon has told its engineers to focus on outcomes rather than how much they use AI, in a note to engineering teams made public on Tuesday. The memo, written by VP and distinguished engineer Terk Terkowitz, argues that neither a developer's role nor their output is defined by AI use, and coins the phrase "Renaissance Developer" for engineers who blend AI tools with human judgement and domain expertise.
The target of the guidance is "tokenmaxxing", the practice of maximising AI token consumption in the belief that more AI usage means more productivity. The memo acknowledges Amazon has seen some correlation between token use and delivery on such teams, but argues the metrics are "deeply flawed" because they are disconnected from what matters. Used as a target rather than a measure, it warns, they could drive negative outcomes, increasing costs and producing overly complex code at odds with Amazon's aim to "invent and simplify".
An Amazon spokesperson confirmed the memo's intent was to discourage tokenmaxxing, pointing to comments from AWS CEO Matt Garman in June encouraging developers to measure outcomes rather than token consumption. The memo also calls out some teams for becoming "less connected to their customers and business", saying more engaged teams take the most advantage of AI and agentic development. It adds that if work does not benefit from current AI tooling, "that is a finding, not a failing".
The approach closely mirrors what Microsoft told its own developers in August, when EVP Jay Parikh said "tokenmaxxing is not what we are optimizing for" and urged focus on outcomes for customers and the business. With two companies of that size questioning token consumption as a productivity measure, The Register suggests more enterprises may instead turn to cheaper open-weight models suited to the task, an approach Garman also advocated in June.
