[AI Large Models Move Toward Time-Based Pricing, 'Peak-Valley Pricing' Expected in the Future] According to CCTV Finance, as AI accelerates its integration into various industries, the token usage of large models continues to climb. Data shows that from July 27 to August 2, the weekly token usage of China's AI large models reached 28.13 trillion tokens, maintaining the global lead for 14 consecutive weeks. Reporters learned from multiple token supply platforms that token demand is currently in a phase of rapid growth, with supply falling short during peak periods. In response to the surging token demand and periodic computing power shortages, the pricing models of many large model enterprises are also evolving, shifting from 'usage-based billing' to 'refined and dynamic pricing.' Kimi has introduced four subscription plans ranging from 39 yuan to 559 yuan per month, while DeepSeek plans to raise the prices of its large model open interfaces. It is expected to launch 'peak-valley pricing' in the future, where peak periods—9:00 AM to 12:00 PM and 2:00 PM to 6:00 PM—will see prices double compared to regular times.
