E.g. if you're using OpenAI, set the `OPENAI_API_KEY` environment variable: ```bash export OPENAI_API_KEY='your-api-key-here' ``` Then with [`uvx`](https://docs.astral.sh/uv/guides/tools/), run: ```bash uvx clai ``` Or to install `clai` globally [with `uv`](https://docs.astral.sh/uv/guides/tools/#installing-tools), run: ```bash uv tool install clai ... clai ``` Or with `pip`, run: ```bash pip install clai ... clai ``` Either way, running `clai` will start an interactive session where you can chat with the AI model. Special commands available in interactive mode: - `/exit`: Exit the session - `/markdown`: Show the last response in markdown format - `/multiline`: Toggle multiline input mode (use Ctrl+D to submit) - `/cp`: Copy the last response to clipboard ## Help ``` usage: clai [-h] [-m [MODEL]] [-a AGENT] [-l] [-t [CODE_THEME]] [--no-stream] [--version] [prompt] Pydantic AI CLI v...
