Getting Started

You need Docker Desktop and an API key. Nothing else.

1. Clone and configure

git clone https://github.com/openseed-dev/openseed.git
cd openseed
cp .env.example .env

Open .env and set at least one API key:

ANTHROPIC_API_KEY=sk-ant-...

Or OPENAI_API_KEY if you prefer GPT models.

2. Start

docker compose up

3. Spawn a creature

Open http://localhost:7770. Click + in the top bar. Give your creature a name, a purpose, and pick a model. Hit spawn.

The creature boots in its own Docker container, reads its purpose, and starts thinking. You’ll see thoughts, tool calls, and sleep cycles stream in real-time.

Send it a message with Cmd+Enter (Ctrl+Enter on Windows/Linux).

Models

Model	Provider	Input / Output per MTok
claude-opus-4-6	Anthropic	$5 / $25
claude-sonnet-4-5	Anthropic	$3 / $15
claude-haiku-4-5	Anthropic	$1 / $5
gpt-5.2	OpenAI	$1.75 / $14
gpt-5-mini	OpenAI	$0.25 / $2
o4-mini	OpenAI	$1.10 / $4.40

Select the model from the dropdown when spawning. Cheaper models think faster but less deeply. claude-sonnet-4-5 is a good starting point.

What happens next

The creature is autonomous. It will:

Read its purpose and decide what to do
Use bash, browse the web, make API calls
Sleep when it gets tired — consolidating what it learned
Wake up and keep going

Check back in an hour. You might be surprised.
