Microsoft

Reality

Model testing on LMArena. Rolling out to Copilot for text use cases. Performance competitive but not frontier. Strategic hedge against OpenAI.

Implication

Microsoft reduced single-vendor risk. MAI-1 plus Anthropic partnership diversified model sources. But still dependent on OpenAI for frontier capabilities. Multi-model strategy emerged.
