It's interesting that Amazon don't appear interested in acquiring Anthropic, which would have seemed like somewhat of a natural fit given that they are already partnered, Anthropic have apparently optimized (or at least adapted) for Trainium, and Amazon don't have their own frontier model. It seems that Amazon are playing this much like Microsoft - seeing themselves are more of a cloud provider, happy to serve anyone…
Or, as a slight variation of that, they think the underlying technology will always be quickly commoditized and that no one will ever be able to maintain much of a moat.
