All Chucki settings are centralized in the RAD Studio Options dialog under Tools -> Options -> Chucki.
General Settings (General)
Under Tools -> Options -> Chucki -> General you will find license management:

License
- Sign in with your Chucki license to activate all features
- Your license determines feature access and usage limits
- Enterprise licenses may include additional capabilities
Detailed configurations for inline completions, models, and chat can be found in the respective sections below.
Provider Sign-Ins and Agent Chat (Chat / Models)
Under Tools -> Options -> Chucki -> Chat you will find agent-specific settings including model sign-ins:

Here you can sign in to supported AI providers and configure local models for the Agent Chat:
Available Providers (Cloud)
- Claude Code: Anthropic’s specialized code model (requires separate installation — see below)
- GitHub Copilot: Access to Claude Sonnet, Claude Haiku, and GPT-5 models
- OpenAI: Access to GPT-5 Codex and other OpenAI models
- Google Gemini: Access to Google’s Gemini model via API key
Claude Code Installation
Claude Code is not bundled with the Chucki installer for licensing reasons and must be installed separately. For detailed instructions, see the Claude Code Installation Guide.
Installation options:
- WinGet (easiest on Windows): See Claude Code guide
- irm (Internet Resource Manager): See Claude Code guide
- npm (Node Package Manager): Use this if you’re on Windows ARM, as WinGet and irm have issues there. See Claude Code guide
Authentication:
Claude Code currently offers no simplified authentication in the IDE. You must authenticate yourself by:
- Direct CLI login: Run the Claude Code CLI and follow the authentication instructions (see Claude Code Guide)
- API Key: Alternatively, you can provide an API key
Local Models for Agent Chat
Local models can also be configured here:
- Click Add under “Local Models”
- Enter the URL of your local model server (e.g.,
http://localhost:1234/v1) - Click Check Connection — verifies connectivity and loads available models
- Select the desired model from the Name dropdown
- Save the configuration
Cloud Provider Sign-In
- Select your chosen provider
- Follow the authentication flow (browser login or API key entry)
- Authorize Chucki to use your account
- Once signed in, that provider’s models become available in the agent chat
See the Overview for details on each model’s capabilities and pricing.
Inline Completions (Completions)
Under Tools -> Options -> Chucki -> Completions you can configure Ghost Text and CodeInsight as well as local models for inline completions:

- Enable/disable inline completions

If you use a local model, click Check Connection to verify availability.
