How to use DeepSeek Harness with Subconscious

Let your AI do the setup. Paste this into Claude Code, Cursor, ChatGPT or any assistant.

Set up DeepSeek Harness to use Subconscious as its model provider.

Subconscious is an inference API for agents. It serves open models through OpenAI- and Anthropic-compatible endpoints, billed per token.
- OpenAI-compatible base URL: https://api.subconscious.dev/v1
- Anthropic-compatible base URL: https://api.subconscious.dev
- Model: subconscious/glm-5.3-marathon
- API key: `subc login` saves it for you. Do not ask me for it.

Follow these steps. Run commands and edit files yourself. For any step in a settings screen, tell me exactly what to click and what to enter.

1. Install the Subconscious CLI
subc is the open-source Subconscious CLI. It signs you in, stores your API key, and wires coding agents to the Subconscious API.
```bash
npm install -g subconscious-cli
```

2. Log in
This opens your browser to sign in or create an account, then saves your API key and a ready-to-use default profile on your machine.
```bash
subc login
```

3. Launch DeepSeek Harness
subc launches the DeepSeek Harness web UI with a temporary Subconscious provider populated from the live model catalog. If DeepSeek Harness is not installed, subc offers to install it first.
```bash
subc dsh
```

When you are done, confirm the tool is using subconscious/glm-5.3-marathon, then summarize what you changed.

To use DeepSeek Harness with Subconscious, install the Subconscious CLI with npm install -g subconscious-cli, run subc login, then run subc dsh. subc points DeepSeek Harness at the OpenAI-compatible Subconscious API, so it runs on open models like GLM-5.3 Marathon, billed per token.

Why run DeepSeek Harness on Subconscious

Long sessions stay fast
2x faster task completion on long tasks than standard open-model inference, especially past 200k tokens of context.
Context that keeps going
The OrangeLine runtime compresses the parts of context that stopped mattering, on the GPU, while the run continues. That gives a 5M+ token context window with no stop-and-compact pause.
Lower cost on long tasks
50% to 80% lower cost on long tasks, because the runtime processes far fewer tokens. Cached input bills at a steep discount, and agentic coding sees cache hit rates above 95%.
Your data stays yours
Prompts, inputs and outputs are not recorded, and nothing you send is used to train a model.

Questions

Which model does DeepSeek Harness use on Subconscious?
The default model on your subc profile, subconscious/glm-5.3-marathon unless you change it. subconscious/deepseek-v4.1-flash-marathon is a cheaper, high-throughput alternative that also takes image input. Run subc with no arguments and choose Set default model to switch.
Does subc change my DeepSeek Harness configuration?
subc launches the DeepSeek Harness web UI with a temporary Subconscious provider populated from the live model catalog. Any persistent change is a merge: subc never replaces your existing DeepSeek Harness config files.
Is DeepSeek Harness on Subconscious OpenAI- or Anthropic-compatible?
This guide connects DeepSeek Harness through the OpenAI-compatible Subconscious API. Subconscious serves both formats: OpenAI Chat Completions at https://api.subconscious.dev/v1 and Anthropic Messages at https://api.subconscious.dev.
How is DeepSeek Harness usage on Subconscious billed?
Per token by default, with no commitment. Heavy users can switch to a monthly token plan: a fixed price for a large daily token allowance shared across your team.
