Build a working voice agent before lunch

AssemblyAI's new Voice Agent API turns the usual STT + LLM + TTS stack into a single WebSocket. Stream audio in, get audio back. ~1s latency, the most accurate speech recognition on the market (the kind that actually hears 16-digit order numbers), and tool calls that stay conversational instead of going silent. $4.50/hr flat. No per-token.
Most devs ship a working agent the same day.
OpenAI's hiring blitz
OpenAI is making moves like it’s assembling the Avengers of tech. First, there’s Justin Uberti, a heavyweight in real-time communication and the creator of WebRTC. After years of redefining how we connect online, he’s now tackling AI’s next big challenges at OpenAI. Whatever he’s working on, it’s safe to say it’ll likely involve revolutionizing how humans and AI interact—or maybe something we haven’t even thought of yet.
And then there’s Caitlin Kalinowski, fresh from Meta, where she was in charge of AR glasses that aimed to bring the sci-fi future to your face. Now, she’s leading OpenAI’s robotics and consumer hardware efforts. Her hire suggests OpenAI might be gearing up for something tactile—robots? AI-optimized devices? Whatever it is, the company isn’t just thinking about ones and zeros anymore; they’re thinking about things you can hold (or that can hold you?).
This hiring blitz isn’t just about picking up talent; it’s about signaling ambition…
