ImageRequestPolicy 改为投影规则加可选单边上限加字节目标,投影是 pixel-budget 或 token-grid 的封闭联合。token 网格求解器放在 dsh-attachment 的 request-projection 里,deepSeekImageTokens 复用同一个求解器计价。DeepSeek 路由默认按 14 px patch、3:1 降采样、1024 token 上限的网格投影,每张请求图片加 4096 像素单边上限,字节目标提高到 2 MiB;显式 imagePixelBudget 与 pi-ai 路由仍走总像素预算。缩放只按长边给定,短边由编码器四舍五入,与投影预测一致。变换版本升到 request-image-v6。 Closes #3929
DeepSeek Harness
English | 中文
DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI.
It is built on an everything-is-a-plugin architecture and powered by Cordis, whose design is described in A Programming Paradigm for Spatiotemporal Composability.
Documentation: https://deepseek-harness.github.io/deepseek-harness/
Developer preview
DeepSeek Harness is in developer preview and iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.
Review the safety notice before running the project.
Run
Run from npm
Install Node.js, then run:
npx @deepseek-ai/dsh web
The command starts the Web UI at http://127.0.0.1:3080 by default and opens it in the default browser for a local launch. An SSH launch only prints the host URL because the SSH client or editor owns the local forwarded address. Pass --no-open to run the server without opening a browser. See Web UI guide.
Run from source
To run from a repository checkout:
git clone https://github.com/deepseek-ai/deepseek-harness.git
cd deepseek-harness
pnpm install
pnpm run build
pnpm dsh web
pnpm run build prepares the repository artifacts. pnpm dsh web uses those built artifacts without rebuilding.
Community and support
- Submit feedback or bug reports through GitHub Discussions.
- Add the
dsh-plugintopic to your plugin repository for discoverability. - Join DeepSeek Harness Discord community.
