## AI overview

Session 1 describes how a team closed the architecture for OpenAI's second Object Storage instance in the same physical region as its primary. The production system was designed for 15 Tbps of GPU-fleet traffic and a three-month delivery timeline, with major architecture decisions completed in one week.

## Source excerpt

OpenAI wanted a second Object Storage instance, in customer-facing production, at 15 Tbps, in three months. Session 1 covers the first week: closing the architecture.
