OpenAI Agents SDK 0.18.1 updates GPT-5.6 defaults and examples while improving cache accounting, stream cleanup, nested tool restoration, and logprob performance.

Why this signal matters
Version 0.18.1 combines a model-default update with several lifecycle fixes that matter in long-running agent services. It improves deterministic realtime cleanup, preserves nested tool state during restoration, closes streams on early exit, and avoids inefficient logprob accumulation. Teams should pin model configuration explicitly if default changes could affect cost, latency, or evaluations.
