AI teams hemorrhaging money on expensive frontier models when cheaper alternatives would work just as well
Companies building AI agents and applications are forced to route all queries through expensive frontier models like Claude Fable or GPT-4, even when cheaper models could handle 80%+ of requests with identical or better results. Teams lack visibility into which model is actually needed for each task, wasting thousands monthly on overkill compute. Current solutions either require manual model selection or expensive A/B testing in production.

Hi HN, we built world-model-optimizer, an open source tool to continually improve a specialized model for an agent. 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 th...
