Guides, tutorials, and insights about embeddings, RAG, and AI infrastructure.
We built "OpenRouter for embeddings" — then learned OpenRouter had quietly shipped embeddings months earlier. Here is the math that killed the paid model, and why the pivot to a free BYOK router and a model-comparison lab is the right one.
