It does this by simulating production tool responses through text world modeling (similar to QwenAgentWorld, summary here https://x.com/silennai/status/2073887455884058814). We can then use this to train a router for frontier, OS, and local models (use defaults or pick which ones to optimize against). wmo ingests agent traces, builds the simulation, embeds the traces, runs different models you choose against the simulation scenarios, and then uses a KNN for model selection…</p><p>71 points; 30 discussion replies on HN. <a href="https://hackerpaper.kaipfister.de/p/2505.19797/">Paper and source history</a>.
