Retries and model fallbacks help a little, Priority PayGo did not go through in the EU, and Provisioned Throughput is too expensive for their volume.

    Slack AI: The Path to Multi-CloudEngineering blog post, Slack Engineering

    Slack added Vertex AI to Slack AI's serving stack in early 2026, for redundancy and for a broader catalog of models. After matching models to features across both clouds, Slack reports about 10% better quality metrics on complex reasoning tasks and about 67% lower latency on high-volume, low-token workloads.

    "~67% reduction in latency for high-velocity, low-token workloads."
