Alexa+ runs on a blend of Amazon Nova and Anthropic models

Alexa+'s leap in capability over the prior Alexa comes from a new underlying architecture blending Amazon's own Nova models with Anthropic's Claude, according to reporting on the rollout.

Pairing an in-house model family with a third-party frontier model is a notable hedge, letting Amazon ship a materially better assistant without waiting on Nova alone to close the capability gap.
