Subconscious

How to use Deep Agents with Subconscious

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

Make Subconscious the model provider in my Deep Agents project.

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: read it from the SUBCONSCIOUS_API_KEY environment variable. Never commit the key or paste it into project files. If it is not set, ask me to create one at https://platform.subconscious.dev.

Follow these steps. Run commands and edit files yourself. If I already have agent code, change its model setup to match the example instead of adding a new file.

1. Install Deep Agents
Install the framework and its OpenAI-compatible client.
```bash
pip install -U deepagents langchain-openai
```

2. Create a Subconscious API key
Sign in at https://platform.subconscious.dev, create an API key, and export it so the tool can read it.
```bash
export SUBCONSCIOUS_API_KEY="your_key"
```

3. Point it at Subconscious
deepagents does not install langchain-openai for you. Always pass a model: the default falls back to an Anthropic model. use_responses_api=False keeps ChatOpenAI on Chat Completions, which is the OpenAI format Subconscious serves.
```python
import os
from deepagents import create_deep_agent
from langchain_openai import ChatOpenAI

model = ChatOpenAI(
    model="subconscious/glm-5.3-marathon",
    base_url="https://api.subconscious.dev/v1",
    api_key=os.environ["SUBCONSCIOUS_API_KEY"],
    use_responses_api=False,
)

agent = create_deep_agent(model=model, system_prompt="You are a careful research assistant.")
result = agent.invoke({"messages": [{"role": "user", "content": "Plan a 3-step study guide for Rust."}]})
print(result["messages"][-1].content)
```

4. Run it
Run the script.
```bash
python agent.py
```

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

To use Deep Agents with Subconscious, create a ChatOpenAI model with base_url="https://api.subconscious.dev/v1" and model="subconscious/glm-5.3-marathon", and pass it to create_deep_agent(model=...). Planning, subagents and file tools then all run on Subconscious, which is built for long agent runs.

Why run Deep Agents on Subconscious

No new SDK
Subconscious speaks OpenAI Chat Completions and Anthropic Messages, so the client you already use works with a base URL change.
Pay per token
No plan and no commitment: sign up, get an API key and pay for the tokens your agents use.
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.

Questions

Which Subconscious model should I use with Deep Agents?
Start with subconscious/glm-5.3-marathon, an open frontier coding model built for long agent runs. subconscious/deepseek-v4.1-flash-marathon is a cheaper, high-throughput alternative that also takes image input. Use the full model ID, including the subconscious/ prefix.
Is Deep Agents on Subconscious OpenAI- or Anthropic-compatible?
This guide connects Deep Agents 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 Deep Agents 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.
