`gitai setup`¶

Save provider credentials and a default model for later commands.

gitai setup
gitai setup --provider gemini
gitai setup --provider openai --api-key sk-... --model openai/gpt-5
gitai setup --provider anthropic --skip-validation

Options¶

Option	Description
`--provider`	Provider to configure: `gemini`, `openai`, or `anthropic`.
`--api-key`	API key to save. If omitted, setup prompts securely.
`--model`	Default LiteLLM model for this provider.
`--validate / --skip-validation`	Validate the API key and selected model before saving. Validation is enabled by default.

Validation¶

When validation is enabled, gitai makes a small LiteLLM request using the selected provider, API key, and model. If the key is invalid, the command exits with an error and does not write the config file.
