ControlFlow is under active development

Pin to a specific version if you want to avoid breaking changes. However, we recommend frequent updates to get new features and bug fixes.

Install ControlFlow

Install ControlFlow with your preferred package manager:

# ControlFlow requires Python 3.9 or greater
pip install -U controlflow 

Provide an API Key

OpenAI

ControlFlow’s default LLM is OpenAI’s GPT-4o model, which provides excellent performance out of the box. To use it, you’ll need to provide an API key as an environment variable:

export OPENAI_API_KEY="your-api-key"

Anthropic

ControlFlow also ships with built-in support for Anthropic. To use an Anthropic model, you’ll need to provide an API key as an environment variable and configure the default LLM:

export ANTHROPIC_API_KEY="your-api-key"
export CONTROLFLOW_DEFAULT_LLM="anthropic/claude-3-5-sonnet-20240620"

Other Providers

ControlFlow supports many other LLM providers as well, though you’ll need to install their respective packages and configure the default LLM appropriately. See the LLM documentation for more information.
