Microsoft will plug Anthropic models into Office 365 features even though that means paying AWS, while still using OpenAI elsewhere. Developers reportedly found Anthropic better for Excel automations and PowerPoint generation, so Microsoft is picking models by task rather than by partner. — This points to a competitive, interoperable AI market where model‑of‑best‑fit and multi‑cloud deals trump single‑vendor allegiance, with implications for antitrust and cloud dominance.
