More than a chat window
DSH is built for ongoing tasks: understand a repository, call tools, record results, and keep moving.

01DEEPSEEK HARNESS / DSH 06
DeepSeek Harness for real AI coding work
DeepSeek Harness (DSH) connects models, tools, context, and execution state; Cocode turns that runtime into a workspace you can start from the desktop or terminal.
Capabilities and limits follow the current release
Composable runtime parts
Models, tools, skills, sessions, sandboxes, and UI are composed through profiles instead of one fixed product shape.
Boundaries stay visible
Cocode makes versions, permissions, model access, and preview status explicit so an experimental runtime remains inspectable.
02Why it matters
DeepSeek Harness solves the runtime problem
A model can reason, but real coding work also needs a workspace, files, terminals, tools, permissions, sessions, and result history. DSH connects those responsibilities.
Cocode is a ready-to-run DSH distribution
Cocode provides defaults, a desktop GUI, a terminal TUI, and model-service options so developers can move from runtime components to a first task with less setup.
One task across GUI, TUI, and SSH
Review context and diffs on the desktop, then continue tests from a terminal or SSH session. Changing entry points does not split the task into separate chats.
06FAQ
Before you start, make the boundaries clear.
What is DeepSeek Harness (DSH)?
DeepSeek Harness is an agent runtime layer for composing models, tools, skills, sessions, sandboxes, and interfaces. It is not a single model or a fixed chat UI.
Is Cocode an official DeepSeek Harness product?
No. Cocode is an independent distribution built on the DeepSeek Harness developer preview.
What development work fits DSH?
It fits continuous coding tasks that require repository context, file edits, commands, tests, diffs, and a durable result trail.
