01DEEPSEEK / HARNESS 02
A coding agent distribution ready for DeepSeek Harness
Cocode combines DeepSeek Harness models, tools, skills, sandboxes, and sessions into desktop and terminal entry points you can use for real work.
Capabilities and limits follow the current release
02Direct answer
Start with what it is.
Cocode is an independent AI coding distribution built on the DeepSeek Harness developer preview. DeepSeek provides the model ecosystem, DSH provides the agent runtime, and Cocode provides GUI, TUI, and an inspectable workflow. It is not an official DeepSeek product.

- DeepSeek Harness
- Agent runtime currently in developer preview
- Cocode
- Independent GUI/TUI distribution built on DSH
- Cocode Nut
- Optional model-service entry point
Plugin-oriented runtime
Models, tools, skills, sessions, and sandboxes are composed through profiles.
Bring your own endpoint
Use an official DeepSeek key, a compatible endpoint, your own gateway, or Cocode Nut.
02Why it matters
Harness runs the agent; Cocode shapes the workflow
You get more than a model entry point: a workspace where sessions, files, terminals, browser tools, and diff previews sit together.
Developer preview, clearly labeled
The upstream Harness is still a developer preview and compatibility can change. Cocode makes the boundaries around versions, models, and runtime explicit.
↗
Clear boundaries make real development work easier to trust.
One Host across GUI and TUI
The desktop and terminal clients share Host scope, profiles, and session data so one task can move between entry points.

Clear boundaries make real development work easier to trust.
05Working flow
Move from setup to verification with a clear result at every step.
This is an executable, reviewable path through a real repository—not an abstract feature list.
- 01
Install and inspect the runtime
Run `cocode doctor` to verify the Host, configuration, terminal, and model entry point.
- 02
Open the workspace
Run `cocode` for TUI or open the desktop client and select the same project directory.
- 03
Choose a model service
Use Cocode Nut, your own DeepSeek-compatible key, a gateway, or a self-hosted endpoint.
- 04
Validate compatibility with a small task
Test reading, a small edit, and a check before committing to a longer tool-driven task.
06Use cases
Decide by the work you actually need to finish.
DeepSeek-powered repository understanding
Combine the model with files, search, and terminal output instead of pasting isolated snippets.
Continuous tool use
Read, edit, test, and review results inside one Session.
GUI and TUI collaboration
Use desktop for structure and diffs, then terminal for SSH, tests, and keyboard-first work.
07Before you start
Runtime requirements and compatibility boundaries
- Cocode is an independent distribution, not an official DeepSeek product
- DeepSeek Harness is a developer preview and compatibility may change
- Tool use, streaming, and protocol support depend on the selected endpoint and binding
- Keep configuration recoverable and run `cocode doctor` after upgrades

cocode09Facts and boundaries
Separate the product layers before judging compatibility.
Similar names do not mean identical roles. Versions, endpoints, and model bindings determine the final behavior.
| Capability | Status | Conditions and evidence scope |
|---|---|---|
| DSH runtime | Integrated | Cocode releases carry a matching runtime path; compatibility can change with the upstream preview. |
| DeepSeek models | Connectable | Use official, compatible, self-hosted endpoints, or Cocode Nut; capability depends on the model. |
| Tool calling | Conditional | The model, protocol, binding, and runtime must all support it. |
| Official relationship | Independent product | Cocode is not an official DeepSeek product or client. |
10Cocode perspective
Connecting DeepSeek does not make every capability compatible.
Cocode treats the model, protocol, tool calling, and runtime as four separate checks. A workflow is available only when those layers align.

06FAQ
Before you start, make the boundaries clear.
Is Cocode an official DeepSeek product?
No. Cocode is an independent distribution built on the DeepSeek Harness developer preview.
Can I use my own model key?
Yes. Cocode supports a DeepSeek-compatible API key, a self-hosted endpoint, a gateway, or Cocode Nut.
Are a DeepSeek model and DeepSeek Harness the same thing?
No. The model performs inference, while DeepSeek Harness organizes agent tools, skills, Sessions, and the runtime environment.
Why can the same DeepSeek model behave differently across endpoints?
Endpoints can expose different protocols, streaming behavior, tool calling, and context limits, so the model name cannot replace a capability test.
