The Post-Training Era: Structural Reshaping of AI Hardware Demand (Collapse and Shift)

English summary

### The Post-Training Era: Structural Reshaping of AI Hardware Demand (Collapse and Shift) Time: 2026-07-31 17:43:35 Content: One-sentence summary: The AI hardware industry will not "die," but the era of "making money while lying down" is over. Core proposition: If large model companies shift their capital expenditure focus from pre-training to post-training, it essentially means: The AI industry moves from a "one-time massive compute investment" model to a "high-frequency, iterative, distributed compute consumption" model. This is not simply "demand decrease" or "demand increase," but a fundamental restructuring of demand composition—some hardware segments will face cliff-like declines, while others will see explosive growth. 1. Quantify first: The compute demand gap between pre-training and post-training. This is the foundational data for understanding all impacts.…
