Amazon is cutting about 100 jobs in its Devices & Services division, which includes Alexa and Echo, as part of a broader tech industry trend toward efficiency amid ongoing AI advancements.

Amazon on Wednesday cut about 100 jobs in its devices and services unit, the group overseeing development of such diverse products as the Kindle, Echo speakers, Alexa voice assistant and Zoox self-driving cars.

Amazon has reduced around 100 roles within its devices and services unit, which is responsible for developing products such as the Alexa voice assistant and Kindle e-reader reports Reuters. The job cuts represent a small fraction of the unit's total workforce and are a result of Amazon's routine business evaluation.
