How cost is calculated and billed
The cost for a customer to use Tonic Fabricate combines the basic access fee with the cost to make the LLM calls that are needed for AI features.
Elements of the Fabricate cost
Basic access
This is the flat monthly amount that is charged to Plus and Enterprise accounts.
It provides overall access to the application and its features.
AI usage and billing
Fabricate's AI features, such as the Data Agent, require calls to a large language model (LLM).
Fabricate uses Anthropic as its LLM provider for the Data Agent. Anthropic charges Tonic.ai for these calls to the Anthropic API.
The incurred cost is based on the volume and complexity of the processed data.
While the technical AI usage is measured in tokens, Tonic.ai tracks and bills usage in dollars.
Each account is granted a monthly AI usage allowance to cover standard AI activity.
If an account exceeds the monthly allowance:
Free accounts - Fabricate pauses access to AI features until the allowance resets at the start of the next month.
Plus accounts - Access to AI features is not interrupted. At the end of the month, Tonic.ai bills for the AI usage that exceeded the allowance.
Enterprise accounts - Access to AI features is not interrupted. Tonic.ai bills calculates and bills quarterly for the AI usage that exceeded the allowance.
The base charge for the additional AI usage is calculated as follows:
(Anthropic cost per token) x (Number of tokens)
The cost per token is based on the publicly listed API prices for Claude Sonnet 4.5 and Haiku 4.5.
Tonic.ai also charges a token fee of $0.50 for each 1 million tokens.
How the billing cycles work
Here is how the billing cycles work for each license plan.
Free plan
The Free plan does not allow any AI usage overages. Each month, Fabricate resets the AI usage allowance based on the account start date.
For example, a Free account starts on October 14.
If the account uses up its monthly allowance before November 13th, then AI features are paused until November 14, when the AI usage allowance is reset. Fabricate resets the AI usage allowance every month on the 14th.
Plus plan
For the Plus plan, the billing cycle is one month. Every month, the AI usage allowance is reset and the account is billed based on the account start date.
For example, a Plus account starts on November 15. On December 15, the AI usage allowance is reset, and the account is charged for the access fee and for any AI usage overage for between November 15 and December 14.
Every month on the 15th, the AI usage allowance is reset and the account is billed for the previous month.
Enterprise plan
For the Enterprise plan, the billing cycle is quarterly, and is based on calendar quarters. The monthly AI usage allowance is lined up to the calendar month.
For example, an account starts on October 21st.
On November 1, December 1, and January 1, Fabricate resets the monthly AI usage allowance.
Shortly after January 1, the account is charged for the platform fees for October through December, and for any AI usage overage from that time.
The next bill is sent after March 31, and covers the platform fees and additional AI usage for January through March.
