DeepAgents：跨提供商默认启用提示缓存，降低Agent成本

two great callouts here, for agents that operate at sustainable cost, you need

1. the right model for the task 2. to make sure prompt caching is enabled

this is hard to support in an application because

1. the right model/provider for a task at this point can change on a weekly basis 2. APIs (including prompt caching specs) are different across providers

deepagents (general purpose, customizable harness) makes this easy because it:

1. is provider agnostic 2. enables prompt caching by default across providers
