Amazon is winding down most of its in-house Nova AI models, including Nova Premier, Omni, Reel, and Canvas, according to The Decoder. While these models will remain accessible to existing users in a limited "keep the lights on" capacity, active development on them has ceased.

The company is now shifting its AI efforts toward a newly formed Frontier Model Research group. This team is tasked with developing a new foundation model that Amazon plans to unveil at its re:Invent conference this fall, signaling a strategic pivot in its artificial intelligence ambitions.

For Japanese investors and market watchers, Amazon’s move highlights the ongoing evolution in AI development strategies among global tech giants, which could influence competitive dynamics in cloud computing and AI services within the region.
