Learn more about synthetic data generation with a deep dive into multi-turn data synthetic. Our AI of the Week section dives into Google's new agentic releases. The opinion section dives into the state of audio models. Last week felt like a clean transition from 'bigger models' to 'model-centric systems': frontier releases aimed at long-running work, open-weight competitors tightening the gap, and infrastructure APIs that treat agents as first-class citizens. OpenAI's GPT-5.2 landed with a clear product thesis: the model isn't just smarter, it's designed to finish multi-step knowledge work end-to-end'spreadsheets, decks, coding, and tool-mediated workflows'without falling apart when context gets long or the task branches. What matters technically is the emphasis on 'long-running agents' and more reliable tool use as a default mode, not a bolted-on trick. That's a subtle shift: the model is being shipped as an operator for workflows, not merely a text generator. If you're building...
