## Configuration

You can configure the CLI to use a specific LLM model by adding or updating your API key:

```bash
tex config gemini-1.5-flash YOUR_MODEL_API_KEY

Replace gemini-1.5-flash with your preferred model name and YOUR_MODEL_API_KEY with your API key.

To list all configured models:

tex list

To remove a model:

tex remove gemini-1.5-creative

To select a model as the default:

tex select gemini-1.5-flash

Usage

Once installed and configured, you can start chatting or debugging commands:

Chat with the LLM

You can either use the chat subcommand or omit it entirely:

# Explicit subcommand
tex chat "Tell me about the solar system"

# Shortcut form (no subcommand)
tex "Tell me about the solar system"

Replace the quoted string with any query you'd like.
