Microsoft 365 Copilot Response Times Cut in Half After September 2024 Overhaul

Microsoft halved inference latency in Microsoft 365 Copilot through enhanced orchestration and GPT-4o integration, arriving in September 2024. The speed gains address a primary friction point—sluggish responses when Copilot accessed context across SharePoint, Exchange, and Teams simultaneously. For enterprise deployments processing extensive organizational data, the performance improvement makes daily use materially more responsive. This marks the most substantial optimization since general availability in September 2023.
