## One-line Takeaway

ByteDance Seed 把 Agent 能力放在办公生产力、GUI+MCP 工具协作和端到端 coding delivery 三个方向同时推进。

## What They Built or Claimed

Seed2.1 强调通用 Agent 和代码工程能力，使用 RL 提升 GUI/非 GUI 行动选择效率，并提出 CreativeWork 内部 benchmark 评估 Notion、Canva、Figma 等生产力场景中的 GUI 与 MCP 协同。

## Technical Signals

- architecture: model + GUI action space + MCP tools。
- tool use: GUI 与 MCP 工具协调。
- memory:
- evaluation: CreativeWork、ProgramBench、众包开发者反馈、内部评估。
- safety:
- deployment: productivity 和 coding scenarios。
- data: 真实代码仓库众包任务反馈。

## Evidence Quality

官方 Seed 博客，包含 benchmark、场景和评估方式，证据强；具体数据表需后续截图/原文复核。

## Gaps for Us

- 需要研究 GUI+MCP 的 Agent 工作流设计。
