Billing FAQ

TLDR:

The cost of each Thread depends on the model you use
Most Threads will cost about $0.01 (1 cent) when running on the "Small" model, and $0.10 when running on the "Large" model (which is the recommended model for most Threads)

What is a Thread?

A Thread is defined as everything Lindy does after being triggered by an event or a user’s message. Threads encompass all the actions taken within that continuous sequence, including multiple steps or messages, until the process is complete.

The number of credits used per Thread depends on input & output length, complexity of the flow, the model used, and whether any premium actions are involved.

What is a credit?

Credits are the currency Lindy uses for billing. The number of credits Lindy uses depends on the following factors:

Thread length and complexity:

For example, Threads that process hundreds of rows of spreadsheet data are more complex and will require more credits than updating one spreadsheet row.

Premium actions:

We offer premium actions that incur additional costs compared to standard actions due to the vendors we use.

These actions include:

1. People Data Labs (our prospecting vendor)
2. Twilio
3. Lindy Knowledge Base (our Pro plan has 5M included indexed characters in the Lindy Knowledge Base)
4. Lindy Embed
5. Lindy Meeting Recording
6. Lindy Mail
7. Webhooks
8. Search the Internet

Model:

In each step of the workflow, you can select which Language Model Lindy uses to reason and take action. We offer models from top providers. Each model has a tradeoff between intelligence, speed, and price (the most intelligent models are slower and more expensive).

What happens once I run out of credits?

Once you run out of credits, Lindy will pause its operations and prompt you to upgrade. You will not be able to initiate new Threads or complete ongoing Threads until your account has sufficient credits.

We provide email notifications to alert you when your credit balance is low to help you manage your usage and avoid interruptions.
