Copilot vs. raw API access: What are you actually paying for?
GitHub argues the choice between Copilot and raw model API access comes down to which layer of the system you need to own: the model call, or the workflow, policy, and harness around it.

The signal
#The question is: why pay for GitHub Copilot when the same models are available through an API? The answer depends on what work you need to own. Copilot plans include a monthly allocation of GitHub AI Credits; metered usage is calculated from input, output, and cached tokens at the listed rate. Raw API access and Copilot address different layers. Take a maintenance task: from a GitHub Issue, inspect the repository, change files, run the test suite in the terminal, and open a pull request. The model call is one step; the surrounding system needs the issue, the diff, repository instructions, permitted commands, and organization policies.
Why now
Why it matters
#当模型这一层的价差被抹平，「自建还是采购」的决策依据就必须换成「哪一层工作是你要自己拥有的」。这篇给出的分法可以直接搬到任何智能体平台的采购评估里。
Background
Technical context
#编码智能体的价值分布在两层：模型调用，以及围绕它的 harness——Issue 上下文、diff、仓库指令、命令白名单、组织策略与计费控制。前者可替换，后者是集成成本，通常被严重低估。
Audience
Who should care
#Next
Learning path
#- 先把自己团队的智能体任务拆成「模型调用」与「周边集成」两栏
- 再逐项判断哪一栏是你的核心竞争力、必须自己拥有
- 最后才比较价格——价格是结论，不是前提

#- 把「外壳」自建一遍，团队真实的年化成本是多少？
- 组织策略与命令白名单这类控制面，采购方案能满足合规要求吗？
- 如果模型供应商更换，自建外壳的迁移成本有多高？
