Frequently asked questions
What counts as a token?

Tokens are the units AI models use to process text. Roughly 1 token = 4 characters of English text. A typical design request uses 500-2,000 tokens. Your monthly budget covers both input (your messages + tool schemas) and output (AI responses + tool calls).

Can I switch plans mid-month?

Yes. Upgrading takes effect immediately and you get the new token budget right away. Downgrading takes effect at the start of your next billing period. No prorated charges on downgrades.

What happens when I hit my token limit?

The AI assistant will let you know you've reached your limit. You can upgrade your plan instantly, or wait until your next billing period when your budget resets. Your work in ArchiCAD, Revit, or SketchUp is never affected.

What's the difference between BYOK and Pro?

BYOK (Bring Your Own Key) gives you all Pro features but you provide your own Anthropic/OpenAI API keys. You pay the providers directly for token usage, so there's no monthly token limit. Ideal if you already have API credits or want full cost control.

Do unused tokens roll over?

No, token budgets reset at the start of each billing period. This keeps pricing simple and predictable. If you consistently need more tokens, upgrading to the next tier is usually more cost-effective.

Which AI models can I use?

Free uses GPT-4.1-mini. Starter adds Claude Sonnet and GPT-4.1 with auto-escalation. Pro and BYOK unlock Claude Opus, the most capable model. The assistant automatically picks the best model for each task.
