OpenRouter Model Fusion

Model fusion is honestly kind of a sleeper hit in the AI space — instead of betting on one model to get it right, you run a bunch side by side and let them vote on the best answer, which is way more reliable than just hoping Claude or GPT drops the perfect response. OpenRouter's doing this with 122 votes and honestly that signal alone tells me people are tired of single-model fragility. It's not the flashiest product but it's the kind of infrastructure move that actually matters when you're building serious AI apps.
