无限流量套餐已死 —— 为何 agent 正在重写生成式 ai 的经济模式
github 和 anthropic 等供应商正从订阅制转向基于用量的计费，因为自主 agent 会消耗海量 token。这标志着随着行业难以将计算成本与商业价值对齐，无限流量定价模式的终结。
generative ai pricing is undergoing a structural shift as agentic workflows that run autonomously for hours render traditional flat-rate subscriptions unsustainable. github copilot is transitioning to usage-based ai credits starting june 2026, specifically targeting its agent and chat features which burn tokens far faster than simple code completions. anthropic reports that nearly half of its agentic tool calls are for software development, a sector with massive compute demands that legacy pricing cannot support. providers are now segmenting tokens by speed and specialization while treating usage as a proxy for value, despite the metric measuring activity rather than actual business outcomes.
