AI Providers

Claunity works with two AI sources: Claude API (Anthropic) and Claude Code (CLI subscription). You can switch between them at any time in Settings.

Claude API — Recommended

Claude is the primary and recommended provider for Claunity. It produces the most consistent action responses, follows multi-step instructions reliably, and handles long context (scripts, scene data, history) very well.

Model	Best for	Cost
claude-sonnet-4-6	Everyday use — best balance of speed, quality, and cost	$$
claude-opus-4-6	Complex tasks — large refactors, multi-file systems, Project Mode	$$$
claude-haiku-4-5	Simple tasks — quick questions, single-line fixes	$

Get your API key at console.anthropic.com. New accounts include free credits to get started.

Start with Sonnet

claude-sonnet-4-6 is the right choice for 90% of tasks. Switch to Opus only when you need maximum quality for a complex, long-running task.

Claude Code — No API key needed

If you have a Claude Pro or Claude Max subscription and use Claude Code CLI, you can use it directly inside Claunity — no API key, no per-token billing.

To use Claude Code mode:

Install Claude Code: npm install -g @anthropic-ai/claude-code
Log in: claude login
In Claunity Settings, set AI Source to Claude Code
Click Test Connection — Claunity checks for the claude binary

How Claude Code mode works

Claunity runs claude -p "..." as a subprocess and reads the output. It uses the same Claude model your subscription provides. Image input (Vision) is not available in Claude Code mode.
