Model cost comparison: GLM-5.3 Flash undercuts Claude by nearly 10x

A test by AI/ML API compared image generation costs using the same prompt ("generate the Backrooms with a monster") across GLM-5.3 Flash, Claude 4.6 Opus, and Tencent's Hy4. While all models completed the task, costs varied significantly: GLM-5.3 Flash cost $0.03, Hy4 preview $0.13, and Claude 4.6 Opus $0.29. This illustrates why the concept of the "best model" is becoming less useful and why model routing will matter more.
