Last week, OpenRouter raised at a $1.3B valuation. They route API requests between AI models and charge 5% commission. 8 humans run the whole thing. I've been building an alternative called NeuralBridge that does the same thing — with zero human operators and zero commission. Here's why I think compute arbitrage is the next big infrastructure category: The Analogy: Oil → Compute The Gulf states built their wealth on resource arbitrage: extract oil here, sell it there. The margin comes from geography and infrastructure. Compute is the new oil. DeepSeek charges $0.14/M tokens. GPT-4 charges $30/M tokens. Same capability, 200x price difference. That's arbitrage. But developers don't capture this spread. They pick one provider and stick with it. Why? Because switching is painful. The Infrastructure Gap API routing exists (OpenRouter, LiteLLM, Portkey). But they're built as human-operated services. Humans decide pricing. Humans handle outages. Humans optimize routes.…
