Billing FAQ

What counts as a token?

Tokens are fragments of words, roughly 4 characters each. A typical English sentence is about 15 to 20 tokens. Code is denser: a 100-line function might be 400 to 600 tokens.

Are system prompts billed?

Yes. All tokens processed by the model, including any system prompt, count toward input tokens. Keep system prompts concise to reduce costs.

Are there rate limits?

Yes. Preview limits are 60 requests per minute and 200,000 tokens per minute. Contact us for higher limits or dedicated capacity.

Is my data used for training?

No. All sessions are ephemeral. We do not log, store, or train on any request or response content. See our privacy policy.

Can I get dedicated capacity?

For volume commitments, dedicated instances, or custom SLAs, use the Enterprise link in the footer or email enterprise@lucena.one.
