Amazon is winding down most of its flagship Nova AI models. One big bet instead of manyResources are shifting to a new effort called Frontier Model Research, or FMR, led by Pieter Abbeel. Prasad left at the end of 2025, and AGI Lab founder David Luan departed in February. It is keeping Nova 2 Lite, Nova 2 Sonic, the Nova Forge customisation service and the Nova Act agent tool. Whether it can also build a frontier model that developers actively choose over Claude, Gemini or GPT is what re:Invent will test.
