+The new default content filtering policy `DefaultV2` delivers the latest safety and security mitigations for the GPT model series (text), including:
+- Prompt Shields for jailbreak attacks on user prompts (filter), 
+- Protected material detection for text (filter) on model completions

Customers have the option to switch between safety defaults and create custom content filtering configurations.
