OpenAI Agents SDK v0.12.2: Realtime Agent with Interruption Detection and Built-In HITL Guardrails

GitHub / OpenAI·medium signal

OpenAI released Agents SDK v0.12.2 on March 14, adding realtime agent capabilities with automatic interruption detection and context management for voice workflows, built-in human-in-the-loop mechanisms configurable per agent run, and input/output guardrails for safety validation. The SDK remains provider-agnostic, supporting OpenAI Responses and Chat Completions APIs as well as 100+ other LLMs. This release makes HITL a first-class SDK primitive rather than an application-level concern.
