    "text": "A great systems-level deep dive into dots3-note Preview.\n\nFrom the Proof–Verify–Refine loop for IMO, to TEMPO and self-evaluation, and all the way to the inference challenges behind ultra-long-horizon agent runs — @GenAI_is_real connects model design, RL, and systems in one coherent picture.\n\nLong-horizon reasoning isn’t just a model problem. It’s an RL and systems problem too.\n\nExactly the kind of technical discussion we hoped the open-weight release of dots3-note Preview would spark. Thanks for the thoughtful breakdown!",
