Scroll through your LinkedIn feed today, and you’ll notice a shift. The era of blindly routing every single piece of user input to a massive, bleeding-edge frontier model (like GPT-4o or Claude 3.5 Sonnet) is officially coming to a close.

As production AI applications scale, throwing a multi-billion parameter model at a trivial “Yes/No” classification task or basic text summarization is quickly becoming the enterprise equivalent of using a cargo ship to cross a swimming pool. It’s slow, it’s painfully expensive, and entirely unnecessary.
