The Decoder flags a genuinely notable shift: Google Cloud hosting its direct rival's flagship models is the clearest sign yet that hyperscalers are becoming model-agnostic storefronts. On our view, this is less about generosity than economics — enterprises increasingly demand multi-model procurement, and whoever owns the distribution layer captures the margin regardless of whose model wins. It also quietly erodes the old exclusivity logic that bound OpenAI to Azure and Anthropic to AWS. The caveat: this is a private preview, and 'only major provider with all three' is a marketing frame that may not survive a single quarter of competitive moves. Expect Microsoft and Amazon to respond quickly; the real battleground is shifting from raw model quality toward enterprise tooling, pricing, and trust.
