II Agent

II-Agent is an open-source intelligent assistant designed to streamline and enhance workflows across multiple domains. It represents a significant advancement in how we interact with technology—shifting from passive tools to intelligent systems capable of independently executing complex tasks.

II-Agent Chat also feature within II-Agent that lets you work across multiple models and tools in one place. The web-hosted version comes with Gemini 3, Sonnet 4.5, and GPT-5 ready to use out of the box. You can connect your own API keys, switch models within a single thread, and use them alongside Claude Skills, GPT-5 Code Interpreter, and text file search.

Optional provider integrations

Some integrations (Google APIs, Anthropic, e2b code interpreter, etc.) are heavy and have many transitive dependencies. To keep development and CI installs fast and deterministic, these are provided as an optional extra named providers.

To install the providers extra locally (recommended when you need provider integrations), use the constraints.txt included in the repository to avoid pip resolver backtracking:

python -m pip install -e "[.providers]" -c constraints.txt

Or install both dev and providers when you need tests and provider integrations:

python -m pip install -e ".[dev]" -c constraints.txt
python -m pip install -e ".[providers]" -c constraints.txt

If you prefer not to install providers, the project will still work for most development tasks without them.
