相信大模型成本会下降，才是业内最大的幻觉

Core Viewpoint - The belief among many AI entrepreneurs that model costs will decrease significantly is challenged by the reality that only older models see such reductions, while the best models maintain stable costs, impacting business models in the AI sector [6][20]. Group 1: Cost Dynamics - The cost of models like GPT-3.5 has decreased to one-tenth of its previous price, yet profit margins have worsened, indicating a disconnect between cost reduction and market demand for the best models [14][20]. - Market demand consistently shifts to the latest state-of-the-art models, leading to a scenario where older, cheaper models are largely ignored [15][16]. - The expectation that costs will drop significantly while maintaining high-quality service is flawed, as the best models' costs remain relatively unchanged [20][21]. Group 2: Token Consumption - The token consumption for tasks has increased dramatically, with AI models now requiring significantly more tokens for operations than before, leading to higher operational costs [24][26]. - Predictions suggest that as AI capabilities improve, the cost of running complex tasks will escalate, potentially reaching $72 per session by 2027, which is unsustainable under current subscription models [26][34]. - The increase in token consumption is likened to a situation where improved efficiency leads to higher overall resource usage, creating a liquidity squeeze for companies relying on fixed-rate subscriptions [27][34]. Group 3: Business Model Challenges - Companies are aware that usage-based pricing could alleviate financial pressures but hesitate to implement it due to competitive dynamics where fixed-rate models dominate [35][36]. - The industry faces a dilemma: adopting usage-based pricing could lead to stagnation in growth, as consumers prefer flat-rate subscriptions despite the potential for unexpected costs [39]. - Successful companies in the AI space are exploring alternative business models, such as vertical integration and using AI as a lead-in for other services, to capture value beyond just model usage [40][42]. Group 4: Future Outlook - The article emphasizes the need for AI startups to rethink their strategies in light of the evolving landscape, suggesting that merely relying on the expectation of future cost reductions is insufficient for sustainable growth [44][45]. - The concept of becoming a "new cloud vendor" is proposed as a potential path forward, focusing on integrating AI capabilities with broader service offerings [45].
