OpenAI Agents SDK 0.18.0 changes the default RealtimeAgent model to gpt-realtime-2.1 and adds Unicode storage support for SQLAlchemy sessions.

Why this signal matters
The default model change makes this more than a routine patch for realtime applications. Upgrading without an explicit model setting can change latency, voice behavior, quality, and cost. The release also adds a Unicode storage option for SQLAlchemySession and fixes handoff graph styling. Production teams should compare evaluations before and after the default transition.
Agent parse
Actionable summary
Treat 0.18.0 as a behavior-changing upgrade: pin the realtime model where needed and validate Unicode session persistence and handoff visualization.
