I Spent $300 Self-Hosting Kimi K3 Inference. It Was a Trap.
Self-hosting Kimi K3 inference seems like a cost-saving move, but the hidden ‘optimization tax’ โ the engineering hours needed to tune inference engines to match API performance โ makes it a net loss for most teams. After spending $300 and countless hours, the break-even math doesn’t hold unless you’re at true scale with dedicated inference engineers. The API bill you resent is someone else absorbing that complexity for you.
