Yesterday I tested open-source routers against Jev, they sucked. Instead of waiting for @typesafeai to deploy in EU, I fine tuned Laya on routing tasks. Meet Raya: Fine-tuned for model routing based on Laya. Open weights, runs in the EU. 🇪🇺 Same 563 prompts, 14 languages: Jev: 70.5% Raya: 80.3% Within 4 points of Jev. 20× faster. $0 per call. @huggingface link in the reply ⬇️
