Copilotが低コストモデルへ移行 — MicrosoftのOpenAI支払い削減のため品質は低下するか
Microsoftはコスト削減のため、ExcelとOutlookでOpenAIとAnthropicのモデルをより安価な自社「mai」モデルに置き換えている。サードパーティAPIへの支出から移行する中、Copilotユーザーは同じサブスクリプション価格でより性能の低いAIを受け取る可能性がある。
microsoft has begun integrating its in-house mai models into excel and outlook, processing tens of thousands of requests previously routed to partners like openai and anthropic. despite benchmarks showing mai models trail competitors like claude sonnet 4.6, microsoft prioritizes cost reduction, with mustafa suleymans stating the goal is to eliminate vendor fees. this strategy suggests a future billing model where cheaper proprietary models are the standard, and high-performance third-party models become paid extras. customers may therefore see stagnation in baseline copilot quality even as microsoft touts clean data licensing for its training sets.
