-## 📈 Why This Matters for the Future of DevOps
+## 📈 The ROI Shift & Competitive Landscape
 
-For CTOs and engineering managers, the calculation is changing. The "value add" of a $200 tool is no longer just about ability, but about **ROI**.
+The "value add" of an AI coding tool is no longer just about its ability to generate code, but about its **ROI**. With the entry of GLM-4.7 into global marketplaces like **OpenRouter**, the pricing floor has been permanently lowered.
 
-If a $3 model can perform 90% of the tasks that a $200 model can, the justification for high-cost enterprise licenses evaporates. This pressure will likely force Western competitors to lower prices or significantly boost their feature sets to maintain market share.
