Can be executed in many different runtimes (including in browsers today, with a polyfill).
These optimizations are difficult to implement, frequently error-prone, and lead to inconsistent behavior across runtimes. Bun's "Direct Streams" optimization takes a deliberately and observably non-standard approach, bypassing much of the spec's machinery entirely. Cloudflare Workers' IdentityTransformStream provides a fast-path for pass-through transforms but is Workers-specific and implements behaviors that are not standard for a TransformStream. Each runtime has its own set of tricks and the natural tendency is toward non-standard solutions, because that's often the only way to make things fast.

Thinking Mode：选中 Ring 模型后，你会发现它多了一个“深度思考”的 toggle。这背后是基于 RLVR（Reinforcement Learning with Verifiable Rewards）训练的 Dense Reward 机制，能让模型在输出结果前，进行多步推理和自我反思。
他强调，未来用户不再需要逐个打开应用，而是通过一句话、一个指令，让 Agent 在后台完成所有跨应用的任务流程。
