無限流量套餐已死 —— 為何 agent 正在重寫生成式 ai 的經濟模式
github 和 anthropic 等供應商正從訂閱制轉向基於用量的計費，因為自主 agent 會消耗海量 token。這標誌著隨著行業難以將計算成本與商業價值對齊，無限流量定價模式的終結。
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.
