Installation

Requirements

pip install arksim

ArkSim uses OpenAI by default. To use other providers, install the corresponding extra:

# Anthropic
pip install "arksim[anthropic]"

# Google
pip install "arksim[google]"

# All providers
pip install "arksim[all]"

git clone https://github.com/arklexai/arksim.git
cd arksim
pip install -e ".[dev]"

This installs in editable mode with test dependencies (pytest, pytest-asyncio).

arksim --help

You should see the available commands: simulate, evaluate, simulate-evaluate, show-prompts, examples, and ui.

You’re all set! Continue to the Quickstart guide to run your first simulation.
