OpenAI Agents SDK Ships TypeScript SDK, RealtimeAgent Class for Voice Agents, GPT-5.4 Computer Use, and Standardized Subagent Coordination API

OpenAI Developer Community·medium signal

OpenAI released a TypeScript version of the Agents SDK alongside a new RealtimeAgent class for voice-first agent construction with speech-to-speech capabilities, plus Traces for Realtime debugging. GPT-5.4 model support was extended to the computer use tool, previously limited to computer-use-preview models. The subagent coordination API was standardized with consistent naming — spawn_agent, send_input, and wait_agent — replacing ad-hoc patterns that caused confusion when composing multi-agent hierarchies.
