但2025年，这个核心逻辑出现了裂缝。DeepSeek的横空出世，彻底打破了“算力至上”的行业迷信——其开发的模型仅用2000块H800 GPU，就实现了与Meta Llama 3（使用1.6万块H100）同等的性能，训练成本仅需560万美元。
TransformStream creates a readable/writable pair with processing logic in between. The transform() function executes on write, not on read. Processing of the transform happens eagerly as data arrives, regardless of whether any consumer is ready. This causes unnecessary work when consumers are slow, and the backpressure signaling between the two sides has gaps that can cause unbounded buffering under load. The expectation in the spec is that the producer of the data being transformed is paying attention to the writer.ready signal on the writable side of the transform but quite often producers just simply ignore it.

更深层的转型，是工具化与服务化。平台不再仅仅因为撮合了一单交易而收费，而是围绕效率提升提供系统、工具与算法能力。当平台开始以管理系统、调度算法、数据分析等方式收费，其角色也随之从中介转向基础设施。
