About OpenAI
OpenAI's feed is mostly essays and legal defense; the real news is turnless realtime voice.
OpenAI's changelog is a corporate blog, and most of what lands in it is not a product change: customer stories, research results, policy explanations, and this week a public response to Apple's lawsuit. The genuine product news in the window is GPT-Live, a realtime voice system built on a turnless speech model and a low-latency architecture, alongside education plugins for ChatGPT Work and Codex aimed at K-12 and college users. Safety and governance posts - third-party evaluation safeguards, a disrupted scam operation, EU AI Act positioning - make up most of the remainder.
