Octoverse 2026:9 月超 40% PR 由 Agent 发起,Copilot 多模型使用升至 61%

  • 年度数据:过去 12 个月 GitHub 推送 179 亿次,超过 2024 与 2025 年合计;提交 343 亿次,合并 PR 13 亿个,Actions 运行 454 亿个作业。
  • Agent 占比:9 月超过 40% 的 PR 由 Agent 发起首版,较 3 月的 17% 提升;当月 Agent 发起 1.1 亿个 PR,约为 3 月的 6 倍。今年新建仓库中,带 Agent 配置文件的仓库平均提交量是无配置文件仓库的 8 倍。
  • Copilot 使用:55% 的 Copilot 月活用户使用 Agent 功能,较一年前 35% 提升;Copilot cloud agent 同比增长 230%。9 月 61% 自行选择模型的 Copilot 用户使用多个模型,付费用户用到 47 个不同模型,单一模型请求占比不超过 25%。
  • 开发者与语言:GitHub 开发者超过 2.25 亿;TypeScript、Python、Rust 的合并 PR 中 AI 参与比例约 40%–44%,Java、C#、C++ 约 21%–34%。
  • 行业意义:报告把 Agent 的使用从“是否采用”推进到 PR 发起、云 Agent 任务与多模型路由的占比;对工具链团队,审查、会话连续性与模型选择成本已成为与生成能力同等重要的指标。 🔗 Octoverse 2026 官方报告
